Handle for a Java Project.
A Java Project internally maintains a devpath that corresponds to the project's classpath. The classpath may include source folders from the current project; jars in the current project, other projects, and the local file system; and binary folders (output location) of other projects. The Java Model presents source elements corresponding to output .class files in other projects, and thus uses the devpath rather than the classpath (which is really a compilation path). The devpath mimics the classpath, except has source folder entries in place of output locations in external projects.
Each JavaProject has a NameLookup facility that locates elements on by name, based on the devpath.

public IPackageFragmentRoot[] findUnfilteredPackageFragmentRoots(IClasspathEntry entry)

    Description copied from interface: IJavaProject
    
    In a Java 9 project, a classpath entry can be filtered using a IClasspathAttribute.LIMIT_MODULES attribute, otherwise for an unnamed module a default set of roots is used as defined in JEP 261. In both cases IJavaProject.findPackageFragmentRoots(IClasspathEntry) will not contain all roots physically present in the container.
    This API can be used to bypass any filter and get really all roots to which the given entry is resolved.

public IPackageFragmentRoot[] findPackageFragmentRoots(IClasspathEntry entry)
```
    Description copied from interface: IJavaProject
    
    Returns the existing package fragment roots identified by the given entry. A classpath entry within the current project identifies a single root.
    If the classpath entry denotes a variable, it will be resolved and return the roots of the target entry (empty if not resolvable).
    If the classpath entry denotes a container, it will be resolved and return the roots corresponding to the set of container entries (empty if not resolvable).
    The result does not include package fragment roots in other projects referenced on this project's classpath.

```
    Description copied from interface: IJavaProject
    
    Returns the first type (excluding secondary types) found following this project's classpath with the given fully qualified name or null if none is found. The fully qualified name is a dot-separated name. For example, a class B defined as a member type of a class A in package x.y should have a the fully qualified name "x.y.A.B". Note that in order to be found, a type name (or its top level enclosing type name) must match its corresponding compilation unit name. As a consequence, secondary types cannot be found using this functionality. To find secondary types use IJavaProject.findType(String, IProgressMonitor) instead.

  - getOutputLocation
```
public IPath getOutputLocation()

```
    Description copied from interface: IJavaProject
    
    Returns the default output location for this project as a workspace- relative absolute path.
    The default output location is where class files are ordinarily generated (and resource files, copied). Each source classpath entry can also specify an output location for the generated class files (and copied resource files) corresponding to compilation units under that source folder. This makes it possible to arrange generated class files for different source folders in different output folders, and not necessarily the default output folder. This means that the generated class files for the project may end up scattered across several folders, rather than all in the default output folder (which is more standard).
    
    Specified by:
    
    getOutputLocation in interface IJavaProject
    
    Returns:
    
    the workspace-relative absolute path of the default output folder

```
    Description copied from interface: IJavaProject
    
    Returns the raw classpath for the project, as a list of classpath entries. This corresponds to the exact set of entries which were assigned using setRawClasspath, in particular such a classpath may contain classpath variable and classpath container entries. Classpath variable and classpath container entries can be resolved using the helper method getResolvedClasspath; classpath variable entries also can be resolved individually using JavaCore#getClasspathVariable).
    Both classpath containers and classpath variables provides a level of indirection that can make the .classpath file stable across workspaces. As an example, classpath variables allow a classpath to no longer refer directly to external JARs located in some user specific location. The classpath can simply refer to some variables defining the proper locations of these external JARs. Similarly, classpath containers allows classpath entries to be computed dynamically by the plug-in that defines that kind of classpath container.
    
    Note that in case the project isn't yet opened, the classpath will be read directly from the associated .classpath file.
    
    Specified by:

    Description copied from interface: IJavaProject
    
    Returns the list of referenced classpath entries stored in the .classpath file of this java project. Clients can store the referenced classpath entries using IJavaProject.setRawClasspath(IClasspathEntry[], IClasspathEntry[], IPath, IProgressMonitor) If the client has not stored any referenced entries for this project, an empty array is returned.

```
    Description copied from interface: IJavaProject
    
    This is a helper method returning the resolved classpath for the project as a list of simple (non-variable, non-container) classpath entries. All classpath variable and classpath container entries in the project's raw classpath will be replaced by the simple classpath entries they resolve to.
    The resulting resolved classpath is accurate for the given point in time. If the project's raw classpath is later modified, or if classpath variables are changed, the resolved classpath can become out of date. Because of this, hanging on resolved classpath is not recommended.
    
    Note that if the resolution creates duplicate entries (i.e. entries which are Object.equals(Object)), only the first one is added to the resolved classpath.
    Specified by:
    
    getResolvedClasspath in interface IJavaProject
    
    Parameters:
    
    ignoreUnresolvedEntry - indicates how to handle unresolvable variables and containers; true indicates that missing variables and unresolvable classpath containers should be silently ignored, and that the resulting list should consist only of the entries that could be successfully resolved; false indicates that a JavaModelException should be thrown for the first unresolved variable or container
    
    Returns:
    
    the resolved classpath for the project as a list of simple classpath entries, where all classpath variable and container entries have been resolved and substituted with their final target entries
    
    Throws:
    JavaModelException - in one of the corresponding situation:
    
    this element does not exist
    
    an exception occurs while accessing its corresponding resource
    
    a classpath variable or classpath container was not resolvable and ignoreUnresolvedEntry is false.

    Retrieve a shared property on a project. If the property is not defined, answers null.

  - readOutputLocation
```
public IPath readOutputLocation()
```
    Description copied from interface: IJavaProject
    
    Returns the default output location for the project as defined by its .classpath file from disk, or null if unable to read the file.
    This output location may differ from the in-memory one returned by getOutputLocation, in case the automatic reconciliation mechanism has not been performed yet. Usually, any change to the .classpath file is automatically noticed and reconciled at the next resource change notification event. However, if the file is modified within an operation, where this change needs to be taken into account before the operation ends, then the output location from disk can be read using this method, and further assigned to the project using setRawClasspath(...).
    The default output location is where class files are ordinarily generated (and resource files, copied). Each source classpath entry can also specify an output location for the generated class files (and copied resource files) corresponding to compilation units under that source folder. This makes it possible to arrange generated class files for different source folders in different output folders, and not necessarily the default output folder. This means that the generated class files for the project may end up scattered across several folders, rather than all in the default output folder (which is more standard).
    In order to manually force a project classpath refresh, one can simply assign the project classpath using the result of this method, as follows: proj.setRawClasspath(proj.readRawClasspath(), proj.readOutputLocation(), monitor) (note that the readRawClasspath/readOutputLocation methods could return null).
    
    Specified by:
    
    readOutputLocation in interface IJavaProject
    
    Returns:
    
    the workspace-relative absolute path of the default output folder

  - readRawClasspath
```
public IClasspathEntry[] readRawClasspath()
```
    Description copied from interface: IJavaProject
    
    Returns the raw classpath for the project as defined by its .classpath file from disk, or null if unable to read the file.
    This classpath may differ from the in-memory classpath returned by getRawClasspath, in case the automatic reconciliation mechanism has not been performed yet. Usually, any change to the .classpath file is automatically noticed and reconciled at the next resource change notification event. However, if the file is modified within an operation, where this change needs to be taken into account before the operation ends, then the classpath from disk can be read using this method, and further assigned to the project using setRawClasspath(...).
    
    Classpath variable and classpath container entries can be resolved using the helper method getResolvedClasspath; classpath variable entries also can be resolved individually using JavaCore#getClasspathVariable).
    
    Note that no check is performed whether the project has the Java nature set, allowing an existing .classpath file to be considered independantly (unlike getRawClasspath which requires the Java nature to be associated with the project).
    
    In order to manually force a project classpath refresh, one can simply assign the project classpath using the result of this method, as follows: proj.setRawClasspath(proj.readRawClasspath(), proj.readOutputLocation(), monitor) (note that the readRawClasspath/readOutputLocation methods could return null).
    
    Specified by:
    
    readRawClasspath in interface IJavaProject
    
    Returns:
    
    the raw classpath from disk for the project, as a list of classpath entries

```
    Description copied from interface: IJavaProject
    
    Sets the default output location of this project to the location described by the given workspace-relative absolute path.
    The default output location is where class files are ordinarily generated (and resource files, copied). Each source classpath entries can also specify an output location for the generated class files (and copied resource files) corresponding to compilation units under that source folder. This makes it possible to arrange that generated class files for different source folders to end up in different output folders, and not necessarily the default output folder. This means that the generated class files for the project may end up scattered across several folders, rather than all in the default output folder (which is more standard).
    Specified by:
    
    setOutputLocation in interface IJavaProject
    
    Parameters:
    
    path - the workspace-relative absolute path of the default output folder
    
    monitor - the progress monitor
    
    Throws:
    JavaModelException - if the classpath could not be set. Reasons include:
    
    This Java element does not exist (ELEMENT_DOES_NOT_EXIST)
    
    The path refers to a location not contained in this project (PATH_OUTSIDE_PROJECT)
    The path is not an absolute path (RELATIVE_PATH)
    The path is nested inside a package fragment root of this project (INVALID_PATH)
    The output location is being modified during resource change event notification (CORE_EXCEPTION)

```
    Description copied from interface: IJavaProject
    
    Sets the classpath of this project using a list of classpath entries. In particular such a classpath may contain classpath variable entries. Classpath variable entries can be resolved individually (JavaCore.getClasspathVariable(String)), or the full classpath can be resolved at once using the helper method IJavaProject.getResolvedClasspath(boolean).
    A classpath variable provides an indirection level for better sharing a classpath. As an example, it allows a classpath to no longer refer directly to external JARs located in some user specific location. The classpath can simply refer to some variables defining the proper locations of these external JARs.
    If it is specified that this operation cannot modify resources, the .classpath file will not be written to disk and no error marker will be generated. To synchronize the .classpath with the in-memory classpath, one can use setRawClasspath(readRawClasspath(), true, monitor).
    Setting the classpath to null specifies a default classpath (the project root). Setting the classpath to an empty array specifies an empty classpath.
    If a cycle is detected while setting this classpath (and if resources can be modified), an error marker will be added to the project closing the cycle. To avoid this problem, use IJavaProject.hasClasspathCycle(IClasspathEntry[]) before setting the classpath.
    This operation acquires a lock on the workspace's root.
    Specified by:
    
    setRawClasspath in interface IJavaProject
    
    Parameters:

    Record a shared persistent property onto a project. Note that it is orthogonal to IResource persistent properties, and client code has to decide which form of storage to use appropriately. Shared properties produce real resource files which can be shared through a VCM onto a server. Persistent properties are not shareable.
    Shared properties end up in resource files, and thus cannot be modified during delta notifications (a CoreException would then be thrown).

A Java project is said to represent a module if any of its source package fragment roots (see IPackageFragmentRoot.K_SOURCE) contains a valid Java module descriptor, or if one of its classpath entries has a valid IClasspathAttribute.PATCH_MODULE attribute affecting the current project. In the latter case the corresponding module description of the location referenced by that classpath entry is returned.
    
    Specified by:
    
    getModuleDescription in interface IJavaProject
    
    Returns:
    
    the IModuleDescription this project represents.
    
    Throws:
    
    JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource
  - getOwnModuleDescription
```
public IModuleDescription getOwnModuleDescription()
                                           throws JavaModelException
```
    Description copied from interface: IJavaProject
    
    Returns the IModuleDescription owned by this project or null if the Java project doesn't own a valid Java module descriptor. This method considers only module descriptions contained in any of the project's source package fragment roots (see IPackageFragmentRoot.K_SOURCE). In particular any IClasspathAttribute.PATCH_MODULE attribute is not considered.
    
    Specified by:
    
    getOwnModuleDescription in interface IJavaProject
    
    Returns:
    
    the IModuleDescription this project owns.
    
    Throws:
    
    JavaModelException - if this element does not exist or if an exception occurs while accessing its corresponding resource
  - getPatchedModules
```
public java.util.List<java.lang.String> getPatchedModules(IClasspathEntry cpEntry)
```
  - getAutomaticModuleDescription
```
public IModuleDescription getAutomaticModuleDescription()
                                                 throws JavaModelException
```
    Throws:
    
    JavaModelException
  - setModuleDescription
```
public void setModuleDescription(IModuleDescription module)
                          throws JavaModelException
```
    Throws:
    
    JavaModelException
  - getManifest
```
public java.util.jar.Manifest getManifest()
```
  - determineModulesOfProjectsWithNonEmptyClasspath
```
public java.util.Set<java.lang.String> determineModulesOfProjectsWithNonEmptyClasspath()
                                                                                throws JavaModelException
```
    Description copied from interface: IJavaProject
    
    When compiling test code in a modular project that has non-source classpath entries which don't have the IClasspathAttribute.MODULE set, the module is assumed to read the unnamed module (which is useful for test-only dependencies that should not be mentioned in the module-info.java). When executing test code that was compiled like this, corresponding "--add-reads" options need to be passed to the java runtime. This method returns the list of modules on the project's classpath for which this is the case.
    
    Specified by:
    
    determineModulesOfProjectsWithNonEmptyClasspath in interface IJavaProject
    
    Returns:
    
    the set of module names
    
    Throws:
    
    JavaModelException - when access to the classpath or module description of the given project fails.
