Method Detail

getId

public String getId()

Specified by:

getId in interface DescriptorLoader<ClassLoaderModel>

load

public final ClassLoaderModel load(File artifactFile,
                                   Map<String,Object> attributes,
                                   ArtifactType artifactType)
                            throws InvalidDescriptorLoaderException

Given an artifact location, it will resolve its dependencies on a Maven based mechanism. It will assume there's a 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:

artifactFile - 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 ArtifactDescriptorConstants.EXPORTED_PACKAGES and ArtifactDescriptorConstants.EXPORTED_RESOURCES

Returns:

a ClassLoaderModel loaded with all its dependencies and URLs.

Throws:

InvalidDescriptorLoaderException
