if you look at AbstractMavenLifecycleParticipant source file:
/**
* Invoked after MavenSession instance has been created.
*
* This callback is intended to allow extensions to inject execution
properties,
* activate profiles and perform similar tasks that affect MavenProject
* instance construction.
*/
// TODO: This is too early for build extensions, so maybe just remove it?
public void afterSessionStart( MavenSession session )
throws MavenExecutionException
{
the TODO seems exactly what you're facing
and if you have a look at place where it is used, ie
DefaultMaven.doExecute(...), you'll see that this method happens really too
early to be able to do anything about this problem
IMHO, you'd better use afterProjectsRead(...) method, which should have the
right classloader prepared
and we should probably change the "TODO" into javadoc, since this shuld be
documented limitation
WDYT?
