Class MavenClassLoaderModelLoader

java.lang.Object

org.mule.runtime.module.deployment.impl.internal.plugin.MavenClassLoaderModelLoader

All Implemented Interfaces:

ClassLoaderModelLoader, DescriptorLoader<ClassLoaderModel>

public class MavenClassLoaderModelLoader
extends Object
implements ClassLoaderModelLoader

This class is responsible of returning the BundleDescriptor of a given plugin's location and also creating a ClassLoaderModel TODO(fernandezlautaro): MULE-11094 this class is the default implementation for discovering dependencies and URLs, which happens to be Maven based. There could be other ways to look for dependencies and URLs (probably for testing purposes where the plugins are done by hand and without maven) which will imply implementing the jira pointed out in this comment.

Since:

4.0

Method Detail

getId

public String getId()

Specified by:

getId in interface DescriptorLoader<ClassLoaderModel>

load

public ClassLoaderModel load(File artifactFolder,
                             Map<String,Object> attributes)
                      throws InvalidDescriptorLoaderException

Given a plugin's location, it will resolve its dependencies on a Maven based mechanism. It will assume there's a ArtifactPluginDescriptor.REPOSITORY folder to look for the artifacts in it (which includes both JAR files as well as POM ones).

It takes care of the transitive compile and runtime dependencies, from which will take the URLs to add them to the resulting ClassLoaderModel, and it will also consume all Mule plugin dependencies so that further validations can check whether or not all plugins are loaded in memory before running an application.

Finally, it will also tell the resulting ClassLoaderModel which packages and/or resources has to export, consuming the attributes from the MuleArtifactLoaderDescriptor.getAttributes() map.

Specified by:

load in interface DescriptorLoader<ClassLoaderModel>

Parameters:

artifactFolder - File where the current plugin to work with.

attributes - a set of attributes to work with, where the current implementation of this class will look for MavenClassLoaderConstants.EXPORTED_PACKAGES and MavenClassLoaderConstants.EXPORTED_RESOURCES

Returns:

a ClassLoaderModel loaded with all its dependencies and URLs.

Throws:

InvalidDescriptorLoaderException
