```
public class JavaCore
extends Plugin
```
The plug-in runtime class for the Java model plug-in containing the core (UI-free) support for Java projects.
Like all plug-in runtime classes (subclasses of Plugin), this class is automatically instantiated by the platform when the plug-in gets activated. Clients must not attempt to instantiate plug-in runtime classes directly.

The single instance of this class can be accessed from any plug-in declaring the Java model plug-in as a prerequisite via JavaCore.getJavaCore(). The Java model plug-in will be activated automatically if not already active.

```
public static final java.lang.String COMPILER_CODEGEN_INLINE_JSR_BYTECODE
```
    Compiler option ID: Inline JSR Bytecode Instruction.
    When enabled, the compiler will no longer generate JSR instructions, but rather inline corresponding subroutine code sequences (mostly corresponding to try finally blocks). The generated code will thus get bigger, but will load faster on virtual machines since the verification process is then much simpler.
    
    This mode is anticipating support for the Java Specification Request 202.
    
    Note that JSR inlining is optional only for target platform lesser than 1.5. From 1.5 on, the JSR inlining is mandatory (also see related setting COMPILER_CODEGEN_TARGET_PLATFORM).

public static final java.lang.String COMPILER_PB_OVERRIDING_PACKAGE_DEFAULT_METHOD
```
    Compiler option ID: Reporting Attempt to Override Package Visible Method.
    A package visible method, which is any method that is not explicitly declared as public, protected or private, is not visible from other packages, and thus cannot be overridden from another package. Attempting to override a package visible method from another package introduces a new method that is unrelated to the original one. When enabling this option, the compiler will signal such situations as an error or a warning.

    When enabled, the compiler will issue an error or warning when public API mentions a type that is not accessible to clients. Here, public API refers to signatures of public fields and methods declared by a public type in an exported package. In these positions types are complained against that are either not public or not in an exported package. Export qualification is not taken into account.

    This issue occurs when a suppress warnings token (like, e.g., "unused") represents a group of problems, and some of the problems in that group are currently disabled (configured as "ignore"). In this situation the compiler may not know if none of the problems in that group could be found within the annotated code section.

    Compiler option ID: Annotation-based Null Analysis.
    This option controls whether the compiler will use null annotations for improved analysis of (potential) null references.
    
    When enabled, the compiler will interpret the annotation types defined using COMPILER_NONNULL_ANNOTATION_NAME and COMPILER_NULLABLE_ANNOTATION_NAME as specifying whether or not a given type includes the value null.
    
    The effect of these analyses is further controlled by the options COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT and COMPILER_PB_NULL_UNCHECKED_CONVERSION.

public static final java.lang.String COMPILER_NULLABLE_ANNOTATION_NAME
```
    Compiler option ID: Name of Annotation Type for Nullable Types.
    This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.
    
    If the annotation specified by this option is applied to a type in a method signature or variable declaration, this will be interpreted as a specification that null is a legal value in that position. Currently supported positions are: method parameters, method return type, fields and local variables.
    
    If a value whose type is annotated with this annotation is dereferenced without checking for null, the compiler will trigger a diagnostic as further controlled by COMPILER_PB_POTENTIAL_NULL_REFERENCE.
    
    The compiler may furthermore check adherence to the null specification as further controlled by COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT and COMPILER_PB_NULL_UNCHECKED_CONVERSION.
    
    This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

    This option defines a comma-separated list of fully qualified Java type names that the compiler may use to perform special null analysis.
    
    The annotation types identified by the names in this list are interpreted in the same way as the annotation identified by COMPILER_NULLABLE_ANNOTATION_NAME. The intention is to support libraries using different sets of null annotations, in addition to those used by the current project. Secondary null annotations should not be used in the project's own source code.
    
    JDT will never actively use any secondary annotation names from this list, i.e., inferred null annotations and content assist proposals mentioning null annotations are always rendered using the primary name from COMPILER_NULLABLE_ANNOTATION_NAME.
    
    This option only has an effect if the option COMPILER_ANNOTATION_NULL_ANALYSIS is enabled.

    Compiler option ID: Name of Annotation Type for Non-Null Types.
    This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.
    
    If the annotation specified by this option is applied to a type in a method signature or variable declaration, this will be interpreted as a specification that null is not a legal value in that position. Currently supported positions are: method parameters, method return type, fields and local variables.
    
    For values declared with this annotation, the compiler will never trigger a null reference diagnostic (as controlled by COMPILER_PB_POTENTIAL_NULL_REFERENCE and COMPILER_PB_NULL_REFERENCE), because the assumption is made that null will never occur at runtime in these positions.
    
    The compiler may furthermore check adherence to the null specification as further controlled by COMPILER_PB_NULL_SPECIFICATION_VIOLATION, COMPILER_PB_NULL_ANNOTATION_INFERENCE_CONFLICT and COMPILER_PB_NULL_UNCHECKED_CONVERSION.

    Compiler option ID: Names of Secondary Annotation Types for Non-Null Types.
    This option defines a comma-separated list of fully qualified Java type names that the compiler may use to perform special null analysis.
    
    The annotation types identified by the names in this list are interpreted in the same way as the annotation identified by COMPILER_NONNULL_ANNOTATION_NAME. The intention is to support libraries using different sets of null annotations, in addition to those used by the current project. Secondary null annotations should not be used in the project's own source code.
    
    JDT will never actively use any secondary annotation names from this list, i.e., inferred null annotations and content assist proposals mentioning null annotations are always rendered using the primary name from COMPILER_NONNULL_ANNOTATION_NAME.

    This option defines a fully qualified Java type name that the compiler may use to perform special null analysis.
    
    If the annotation is applied without an argument, all unannotated types in method signatures and field declarations within the annotated element will be treated as if they were specified with the non-null annotation (see COMPILER_NONNULL_ANNOTATION_NAME).

    Depending on this option, the compiler will issue either an error or a warning whenever one of the following situations is detected:
    1. A method declared with a nonnull annotation returns a nullable expression.
    2. A nullable expression is passed as an argument in a method call where the corresponding parameter of the called method is declared with a nonnull annotation.
    3. A nullable expression is assigned to a local variable that is declared with a nonnull annotation.
    4. A method that overrides an inherited method declared with a nonnull annotation tries to relax that contract by specifying a nullable annotation (prohibition of contravariant return).
    5. A method that overrides an inherited method which has a nullable declaration for at least one of its parameters, tries to tighten that null contract by specifying a nonnull annotation for its corresponding parameter (prohibition of covariant parameters).
    6. A non-static field with a nonnull annotation is not definitely assigned at the end of each constructor.
    7. A static field with a nonnull annotation is not definitely assigned in static initializers.
    In the above an expression is considered as nullable if either it is statically known to evaluate to the value null, or if it is declared with a nullable annotation.

    2. An expression that is statically known to evaluate to a null value on some flow is passed as an argument in a method call where the corresponding parameter of the called method is declared with a nonnull annotation.

    When enabled, the compiler will issue an error or a warning whenever one of the following situations is detected:
    1. A method declared with a nonnull annotation returns an expression for which insufficient nullness information is available for statically proving that no flow will pass a null value at runtime.
    2. An expression for which insufficient nullness information is available for statically proving that it will never evaluate to a null value at runtime is passed as an argument in a method call where the corresponding parameter of the called method is declared with a nonnull annotation.
    3. An expression for which insufficient nullness information is available for statically proving that it will never evaluate to a null value at runtime is assigned to a local variable that is declared with a nonnull annotation.
    Unchecked null conversion is usually a consequence of using other unannotated variables or methods.

    Compiler option ID: Reporting problems detected by pessimistic null analysis for free type variables.
    Unless set to "ignore", type variables not affected by any explicit null annotation are pessimistically analyzed in two directions: When reading a value of this type, it is assumed to be nullable. When this type appears as the required type (i.e., at the left hand side of an assignment or variable initialization, or as the method return type against which a return statement is being checked) the type is considered to require the nonnull property.
    
    Problems reported due to this pessimistic analysis are reported with the level given in this option.

    Annotation inheritance will use the effective nullness of the overridden method after transitively applying inheritance and after applying any default nullness (see COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_NAME) at the site of the overridden method.
    
    If different implicit null annotations (from a nonnull default and/or overridden methods) are applicable to the same type in a method signature, this is flagged as an error and an explicit null annotation must be used to disambiguate.

```
    Compiler option ID: Reporting Dropped Nonnull Parameter Annotations.
    When enabled, the compiler will issue an error or a warning against a parameter of a method that overrides an inherited method if all of the following hold:
    - The overridden method declares the corresponding parameter as non-null (see COMPILER_NONNULL_ANNOTATION_NAME).
    - The parameter in the overriding method has no null annotation.
    - The overriding method is not affected by a nullness default (see COMPILER_NONNULL_BY_DEFAULT_ANNOTATION_NAME).
    - Inheritance of null annotations is disabled (see COMPILER_INHERIT_NULL_ANNOTATIONS).
    This particular situation bears the same inherent risk as any unannotated method parameter, because the compiler's null ananysis cannot decide wither null is or is not a legal value for this parameter. However, the annotation in the overridden method suggests that the parameter should also be annotated as non-null. If that is not intended or possible, it is recommended to annotate the parameter as nullable, in order to make this (legal) change of contract explicit.

    When enabled, the compiler will issue an error or a warning against a method call if all of the following hold:
    - The method's declared return type is a type variable without any null annotation.
    - For the given invocation this type variable is substituted with a nonnull type.
    - The type declaring the method is provided by a third-party library.
    - No null annotations exist for this library type, neither in its class file nor using external annotations.
    This particular situation leverages the option to consistently substitute all occurrences of a type variable with a nonnull type, but it bears the risk that the library type may not be aware of null annotations thus lacking a necessary @Nullable annotation for a particular occurrence of a type variable.

    When a given line of code bears multiple tags, each tag will be reported separately. Moreover, a tag immediately followed by another tag will be reported using the contents of the next non-empty tag of the line, if any.
    
    Note that tasks messages are trimmed. If a tag is starting with a letter or digit, then it cannot be leaded by another letter or digit to be recognized ("fooToDo" will not be recognized as a task for tag "ToDo", but "foo#ToDo" will be detected for either tag "ToDo" or "#ToDo"). Respectively, a tag ending with a letter or digit cannot be followed by a letter or digit to be recognized ("ToDofoo" will not be recognized as a task for tag "ToDo", but "ToDo:foo" will be detected either for tag "ToDo" or "ToDo:").

  - addElementChangedListener
```
public static void addElementChangedListener(IElementChangedListener listener)
```
    Adds the given listener for changes to Java elements. Has no effect if an identical listener is already registered.
    This listener will only be notified during the POST_CHANGE resource change notification and any reconcile operation (POST_RECONCILE).
    
    For finer control of the notification, use addElementChangedListener(IElementChangedListener,int), which allows to specify a different eventMask.
    
    Parameters:
    
    listener - the listener
    
    See Also:
    
    ElementChangedEvent
  - addElementChangedListener
```
public static void addElementChangedListener(IElementChangedListener listener,
                                             int eventMask)
```
    Adds the given listener for changes to Java elements. Has no effect if an identical listener is already registered. After completion of this method, the given listener will be registered for exactly the specified events. If they were previously registered for other events, they will be deregistered.
    Once registered, a listener starts receiving notification of changes to java elements in the model. The listener continues to receive notifications until it is replaced or removed.
    
    Listeners can listen for several types of event as defined in ElementChangeEvent. Clients are free to register for any number of event types however if they register for more than one, it is their responsibility to ensure they correctly handle the case where the same java element change shows up in multiple notifications. Clients are guaranteed to receive only the events for which they are registered.
    
    Parameters:
    
    listener - the listener
    
    eventMask - the bit-wise OR of all event types of interest to the listener

                                                 throws JavaModelException
```
    Answers the project specific value for a given classpath container. In case this container path could not be resolved, then will answer null. Both the container path and the project context are supposed to be non-null.
    The containerPath is a formed by a first ID segment followed with extra segments, which can be used as additional hints for resolution. If no container was ever recorded for this container path onto this project (using setClasspathContainer, then a ClasspathContainerInitializer will be activated if any was registered for this container ID onto the extension point "org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer".
    
    There is no assumption that the returned container must answer the exact same containerPath when requested IClasspathContainer#getPath. Indeed, the containerPath is just an indication for resolving it to an actual container object.
    
    Classpath container values are persisted locally to the workspace, but are not preserved from a session to another. It is thus highly recommended to register a ClasspathContainerInitializer for each referenced container (through the extension point "org.aspectj.org.eclipse.jdt.core.ClasspathContainerInitializer").
    
    Parameters:
    
    containerPath - the name of the container, which needs to be resolved
    
    project - a specific project in which the container is being resolved
    
    Returns:
    
    the corresponding classpath container or null if unable to find one.
    
    Throws:
    
    JavaModelException - if an exception occurred while resolving the container, or if the resolved container contains illegal entries (contains CPE_CONTAINER entries or null entries).

public static ClasspathContainerInitializer getClasspathContainerInitializer(java.lang.String containerID)
```
    Helper method finding the classpath container initializer registered for a given classpath container ID or null if none was found while iterating over the contributions to extension point to the extension point "org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer".
    A containerID is the first segment of any container path, used to identify the registered container initializer.
    
    Parameters:
    
    containerID - - a containerID identifying a registered initializer
    
    Returns:
    
    ClasspathContainerInitializer - the registered classpath container initializer or null if none was found.

```
public static IPath getClasspathVariable(java.lang.String variableName)
```
    Returns the path held in the given classpath variable. Returns null if unable to bind.
    Classpath variable values are persisted locally to the workspace, and are preserved from session to session.
    
    Note that classpath variables can be contributed registered initializers for, using the extension point "org.aspectj.org.eclipse.jdt.core.classpathVariableInitializer". If an initializer is registered for a variable, its persisted value will be ignored: its initializer will thus get the opportunity to rebind the variable differently on each session.
    
    Parameters:
    
    variableName - the name of the classpath variable
    
    Returns:
    
    the path, or null if none

    Helper constants have been defined on JavaCore for each of the option IDs (categorized in Code assist option ID, Compiler option ID and Core option ID) and some of their acceptable values (categorized in Option value). Some options accept open value sets beyond the documented constant values.
    
    Note: each release may add new options.

  - getResolvedClasspathEntry
```
public static IClasspathEntry getResolvedClasspathEntry(IClasspathEntry entry)
```
    This is a helper method, which returns the resolved classpath entry denoted by a given entry (if it is a variable entry). It is obtained by resolving the variable reference in the first segment. Returns null if unable to resolve using the following algorithm:
    - if variable segment cannot be resolved, returns null
    - finds a project, JAR or binary folder in the workspace at the resolved path location
    - if none finds an external JAR file or folder outside the workspace at the resolved path location
    - if none returns null
    Variable source attachment path and root path are also resolved and recorded in the resulting classpath entry.
    
    NOTE: This helper method does not handle classpath containers, for which should rather be used JavaCore#getClasspathContainer(IPath, IJavaProject).
    Parameters:
    
    entry - the given variable entry
    
    Returns:
    
    the resolved library or project classpath entry, or null if the given variable entry could not be resolved to a valid classpath entry

  - initializeAfterLoad
```
public static void initializeAfterLoad(IProgressMonitor monitor)
                                throws CoreException
```
    Initializes JavaCore internal structures to allow subsequent operations (such as the ones that need a resolved classpath) to run full speed. A client may choose to call this method in a background thread early after the workspace has started so that the initialization is transparent to the user.
    However calling this method is optional. Services will lazily perform initialization when invoked. This is only a way to reduce initialization overhead on user actions, if it can be performed before at some appropriate moment.
    This initialization runs across all Java projects in the workspace. Thus the workspace root scheduling rule is used during this operation.
    This method may return before the initialization is complete. The initialization will then continue in a background thread.
    This method can be called concurrently.
    
    Parameters:
    
    monitor - a progress monitor, or null if progress reporting and cancellation are not desired
    
    Throws:
    
    CoreException - if the initialization fails, the status of the exception indicates the reason of the failure

    Creates and returns a new classpath entry of kind CPE_CONTAINER for the given path. This method is fully equivalent to calling newContainerEntry(containerPath, new IAccessRule[0], new IClasspathAttribute[0], isExported).
    
    Parameters:

                                                boolean isExported)
```
    Creates and returns a new classpath entry of kind CPE_CONTAINER for the given path. The path of the container will be used during resolution so as to map this container entry to a set of other classpath entries the container is acting for.
    A container entry allows to express indirect references to a set of libraries, projects and variable entries, which can be interpreted differently for each Java project where it is used. A classpath container entry can be resolved using JavaCore.getResolvedClasspathContainer, and updated with JavaCore.classpathContainerChanged
    
    A container is exclusively resolved by a ClasspathContainerInitializer registered onto the extension point "org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer".
    
    A container path must be formed of at least one segment, where:
    - the first segment is a unique ID identifying the target container, there must be a container initializer registered onto this ID through the extension point "org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer".
    - the remaining segments will be passed onto the initializer, and can be used as additional hints during the initialization phase.
    Example of an ClasspathContainerInitializer for a classpath container denoting a default JDK container:
```
 containerEntry = JavaCore.newContainerEntry(new Path("MyProvidedJDK/default"));

 <extension
    point="org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer">
    <containerInitializer
       id="MyProvidedJDK"
       class="com.example.MyInitializer"/>
 
```
    The access rules determine the set of accessible source and class files in the container. If the list of access rules is empty, then all files in this container are accessible. See IAccessRule for a detailed description of access rules. Note that if an entry defined by the container defines access rules, then these access rules are combined with the given access rules. The given access rules are considered first, then the entry's access rules are considered.
    
    The extraAttributes list contains name/value pairs that must be persisted with this entry. If no extra attributes are provided, an empty array must be passed in.
    Note that this list should not contain any duplicate name.
    
    The isExported flag indicates whether this entry is contributed to dependent projects. If not exported, dependent projects will not see any of the classes from this entry. If exported, dependent projects will concatenate the accessible files patterns of this entry with the accessible files patterns of the projects, and they will concatenate the non accessible files patterns of this entry with the non accessible files patterns of the project.
    
    Note that this operation does not attempt to validate classpath containers or access the resources at the given paths.
    Parameters:
    
    containerPath - the path identifying the container, it must be formed of at least one segment (ID+hints)
    
    accessRules - the possibly empty list of access rules for this entry
    
    extraAttributes - the possibly empty list of extra attributes to persist with this entry
    
    isExported - a boolean indicating whether this entry is contributed to dependent projects in addition to the output location

                                              boolean isExported)
```
    Creates and returns a new classpath entry of kind CPE_LIBRARY for the JAR or folder identified by the given absolute path. This specifies that all package fragments within the root will have children of type IClassFile.
    A library entry is used to denote a prerequisite JAR or root folder containing binaries. The target JAR can either be defined internally to the workspace (absolute path relative to the workspace root), or externally to the workspace (absolute path in the file system). The target root folder can also be defined internally to the workspace (absolute path relative to the workspace root), or - since 3.4 - externally to the workspace (absolute path in the file system). Since 3.5, the path to the library can also be relative to the project using ".." as the first segment.
    
    e.g. Here are some examples of binary path usage
    - "c:\jdk1.2.2\jre\lib\rt.jar" - reference to an external JAR on Windows
    - "/Project/someLib.jar" - reference to an internal JAR on Windows or Linux
    - "/Project/classes/" - reference to an internal binary folder on Windows or Linux
    - "/home/usr/classes" - reference to an external binary folder on Linux
    - "../../lib/someLib.jar" - reference to an external JAR that is a sibling of the workspace on either platform
    Note that on non-Windows platform, a path "/some/lib.jar" is ambiguous. It can be a path to an external JAR (its file system path being "/some/lib.jar") or it can be a path to an internal JAR ("some" being a project in the workspace). Such an ambiguity is solved when the classpath entry is used (e.g. in IJavaProject.getPackageFragmentRoots()). If the resource "lib.jar" exists in project "some", then it is considered an internal JAR. Otherwise it is an external JAR.
    Also note that this operation does not attempt to validate or access the resources at the given paths.
    The access rules determine the set of accessible class files in the library. If the list of access rules is empty then all files in this library are accessible. See IAccessRule for a detailed description of access rules.
    
    The extraAttributes list contains name/value pairs that must be persisted with this entry. If no extra attributes are provided, an empty array must be passed in.
    Note that this list should not contain any duplicate name.
    
    The isExported flag indicates whether this entry is contributed to dependent projects. If not exported, dependent projects will not see any of the classes from this entry. If exported, dependent projects will concatenate the accessible files patterns of this entry with the accessible files patterns of the projects, and they will concatenate the non accessible files patterns of this entry with the non accessible files patterns of the project.
    
    Since 3.5, if the library is a ZIP archive, the "Class-Path" clause (if any) in the "META-INF/MANIFEST.MF" is read and referenced ZIP archives are added to the resolved classpath.
    Parameters:
    
    path - the path to the library
    
    sourceAttachmentPath - the absolute path of the corresponding source archive or folder, or null if none. Note, since 3.0, an empty path is allowed to denote no source attachment. and will be automatically converted to null. Since 3.4, this path can also denote a path external to the workspace.
    
    sourceAttachmentRootPath - the location of the root of the source files within the source archive or folder or null if this location should be automatically detected.

                                             IClasspathAttribute[] extraAttributes)
```
    Creates and returns a new classpath entry of kind CPE_SOURCE for the project's source folder identified by the given absolute workspace-relative path using the given inclusion and exclusion patterns to determine which source files are included, and the given output path to control the output location of generated files.
    The source folder is referred to using an absolute path relative to the workspace root, e.g. /Project/src. A project's source folders are located with that project. That is, a source classpath entry specifying the path /P1/src is only usable for project P1.
    
    The inclusion patterns determines the initial set of source files that are to be included; the exclusion patterns are then used to reduce this set. When no inclusion patterns are specified, the initial file set includes all relevant files in the resource tree rooted at the source entry's path. On the other hand, specifying one or more inclusion patterns means that all and only files matching at least one of the specified patterns are to be included. If exclusion patterns are specified, the initial set of files is then reduced by eliminating files matched by at least one of the exclusion patterns. Inclusion and exclusion patterns look like relative file paths with wildcards and are interpreted relative to the source entry's path. File patterns are case-sensitive can contain '**', '*' or '?' wildcards (see IClasspathEntry.getExclusionPatterns() for the full description of their syntax and semantics). The resulting set of files are included in the corresponding package fragment root; all package fragments within the root will have children of type ICompilationUnit.
    
    For example, if the source folder path is /Project/src, there are no inclusion filters, and the exclusion pattern is com/xyz/tests/**, then source files like /Project/src/com/xyz/Foo.java and /Project/src/com/xyz/utils/Bar.java would be included, whereas /Project/src/com/xyz/tests/T1.java and /Project/src/com/xyz/tests/quick/T2.java would be excluded.
    
    Additionally, a source entry can be associated with a specific output location. By doing so, the Java builder will ensure that the generated ".class" files will be issued inside this output location, as opposed to be generated into the project default output location (when output location is null). Note that multiple source entries may target the same output location. The output location is referred to using an absolute path relative to the workspace root, e.g. "/Project/bin", it must be located inside the same project as the source folder.
    
    Also note that all sources/binaries inside a project are contributed as a whole through a project entry (see JavaCore.newProjectEntry). Particular source entries cannot be selectively exported.
    
    The extraAttributes list contains name/value pairs that must be persisted with this entry. If no extra attributes are provided, an empty array must be passed in.
    Note that this list should not contain any duplicate name.
    
    Parameters:
    
    path - the absolute workspace-relative path of a source folder
    
    inclusionPatterns - the possibly empty list of inclusion patterns represented as relative paths
    
    exclusionPatterns - the possibly empty list of exclusion patterns represented as relative paths
    
    specificOutputLocation - the specific output location for this source entry (null if using project default ouput location)
    
    extraAttributes - the possibly empty list of extra attributes to persist with this entry

```
    Creates and returns a new classpath entry of kind CPE_VARIABLE for the given path. The first segment of the path is the name of a classpath variable. The trailing segments of the path will be appended to resolved variable path.
    A variable entry allows to express indirect references on a classpath to other projects or libraries, depending on what the classpath variable is referring.
    
    It is possible to register an automatic initializer (ClasspathVariableInitializer), which will be invoked through the extension point "org.aspectj.org.eclipse.jdt.core.classpathVariableInitializer". After resolution, a classpath variable entry may either correspond to a project or a library entry.
    
    e.g. Here are some examples of variable path usage
    - "JDTCORE" where variable JDTCORE is bound to "c:/jars/jdtcore.jar". The resolved classpath entry is denoting the library "c:\jars\jdtcore.jar"
    - "JDTCORE" where variable JDTCORE is bound to "/Project_JDTCORE". The resolved classpath entry is denoting the project "/Project_JDTCORE"
    - "PLUGINS/com.example/example.jar" where variable PLUGINS is bound to "c:/eclipse/plugins". The resolved classpath entry is denoting the library "c:\eclipse\plugins\com.example\example.jar"
    The access rules determine the set of accessible class files in the project or library. If the list of access rules is empty then all files in this project or library are accessible. See IAccessRule for a detailed description of access rules.
    
    The extraAttributes list contains name/value pairs that must be persisted with this entry. If no extra attributes are provided, an empty array must be passed in.
    Note that this list should not contain any duplicate name.
    
    The isExported flag indicates whether this entry is contributed to dependent projects. If not exported, dependent projects will not see any of the classes from this entry. If exported, dependent projects will concatenate the accessible files patterns of this entry with the accessible files patterns of the projects, and they will concatenate the non accessible files patterns of this entry with the non accessible files patterns of the project.
    
    Note that this operation does not attempt to validate classpath variables or access the resources at the given paths.
    Parameters:
    
    variablePath - the path of the binary archive; first segment is the name of a classpath variable
    
    variableSourceAttachmentPath - the path of the corresponding source archive, or null if none; if present, the first segment is the name of a classpath variable (not necessarily the same variable as the one that begins variablePath)
    
    variableSourceAttachmentRootPath - the location of the root of the source files within the source archive or null if variableSourceAttachmentPath is also null
    
    accessRules - the possibly empty list of access rules for this entry

```
    Returns an array of classpath entries that are referenced directly or indirectly by a given classpath entry. For the entry kind IClasspathEntry.CPE_LIBRARY, the method returns the libraries that are included in the Class-Path section of the MANIFEST.MF file. If a referenced JAR file has further references to other library entries, they are processed recursively and added to the list. For entry kinds other than IClasspathEntry.CPE_LIBRARY, this method returns an empty array.
    When a non-null project is passed, any additional attributes that may have been stored previously in the project's .classpath file are retrieved and populated in the corresponding referenced entry. If the project is null, the raw referenced entries are returned without any persisted attributes. For more details on storing referenced entries, see IJavaProject.setRawClasspath(IClasspathEntry[], IClasspathEntry[], IPath, IProgressMonitor).
    
    Parameters:
    
    libraryEntry - the library entry whose referenced entries are sought
    
    project - project where the persisted referenced entries to be retrieved from. If null persisted attributes are not attempted to be retrieved.
    
    Returns:
    
    an array of classpath entries that are referenced directly or indirectly by the given entry. If not applicable, returns an empty array.

    After running a method that modifies java elements, registered listeners receive after-the-fact notification of what just transpired, in the form of a element changed event. This method allows clients to call a number of methods that modify java elements and only have element changed event notifications reported at the end of the entire batch.
    
    If this method is called outside the dynamic scope of another such call, this method runs the action and then reports a single element changed event describing the net effect of all changes done to java elements by the action.
    
    If this method is called in the dynamic scope of another such call, this method simply runs the action.
    
    Parameters:
    
    action - the action to perform
    
    monitor - a progress monitor, or null if progress reporting and cancellation are not desired
    
    Throws:
    
    CoreException - if the operation failed.

public static void setClasspathContainer(IPath containerPath,

                                         IClasspathContainer[] respectiveContainers,
                                         IProgressMonitor monitor)
                                  throws JavaModelException
```
    Bind a container reference path to some actual containers (IClasspathContainer). This API must be invoked whenever changes in container need to be reflected onto the JavaModel. Containers can have distinct values in different projects, therefore this API considers a set of projects with their respective containers.
    containerPath is the path under which these values can be referenced through container classpath entries (IClasspathEntry#CPE_CONTAINER). A container path is formed by a first ID segment followed with extra segments, which can be used as additional hints for the resolution. The container ID is used to identify a ClasspathContainerInitializer registered on the extension point "org.aspectj.org.eclipse.jdt.core.classpathContainerInitializer".
    
    There is no assumption that each individual container value passed in argument (respectiveContainers) must answer the exact same path when requested IClasspathContainer#getPath. Indeed, the containerPath is just an indication for resolving it to an actual container object. It can be delegated to a ClasspathContainerInitializer, which can be activated through the extension point "org.aspectj.org.eclipse.jdt.core.ClasspathContainerInitializer").
    
    In reaction to changing container values, the JavaModel will be updated to reflect the new state of the updated container. A combined Java element delta will be notified to describe the corresponding classpath changes resulting from the container update. This operation is batched, and automatically eliminates unnecessary updates (new container is same as old one). This operation acquires a lock on the workspace's root.
    
    This functionality cannot be used while the workspace is locked, since it may create/remove some resource markers.
    
    Classpath container values are persisted locally to the workspace, but are not preserved from a session to another. It is thus highly recommended to register a ClasspathContainerInitializer for each referenced container (through the extension point "org.aspectj.org.eclipse.jdt.core.ClasspathContainerInitializer").
    
    Note: setting a container to null will cause it to be lazily resolved again whenever its value is required. In particular, this will cause a registered initializer to be invoked again.
    
    Parameters:
    
    containerPath - - the name of the container reference, which is being updated
    
    affectedProjects - - the set of projects for which this container is being bound
    
    respectiveContainers - - the set of respective containers for the affected projects
    
    monitor - a monitor to report progress

    Compile the given module description in the context of its enclosing Java project and add class file attributes using the given map of attribute values.
    In this map, the following keys are supported
    IAttributeNamesConstants.MODULE_MAIN_CLASS
    
    The associated value will be used for the ModuleMainClass attribute.
    
    IAttributeNamesConstants.MODULE_PACKAGES
    
    If the associated value is an empty string, then the compiler will generate a ModulePackages attribute with a list of packages that is computed from
    
    all exports directives
    all opens directives
    the implementation classes of all provides directives.
    If the associated value is not empty, it must be a comma-separated list of package names, which will be added to the computed list.
    No other keys are supported in this version, but more keys may be added in the future.
