public class Loader
extends java.lang.Object

Bootstrap a raven installation, allows a non raven aware loader to create a repository structure etc and boot into an artifact class loader driven world view without having to actually have raven installed to begin with. Also handles splash screen management and a few other conveniences.

targetGroup - Group ID of the Maven2 artifact to bootstrap from

targetArtifact - Artifact ID of the Maven2 artifact to bootstrap from

targetVersion - Version of the Maven2 artifact to bootstrap from

className - Class name to return from the target artifact

listener - a RepositoryListener that will be informed of repository events

Returns:

Class object loaded by raven as specified by the arguments to this method call

Throws:
