OK, I'm getting the dependencies to resolve and I can amend the classpath, but I think I've hit a road block for multi module builds.
LifeCycleParticipant is only ever called once at the root. This means that if I have a project with 2 modules where ModuleB depends on ModuleA then I'm not going to be able extract and add ModuleA and it's classes when the LifeCycleParticipant executes because ModuleA will not have been built yet. Is there some way to get the LifeCycleParticipant called for every module of the build?
