Re: [m2e-users] Project configurator to inject new dependencies to a bui

[Igor Fedorenko <igor@xxxxxxxxxxxxxx>]

I believe build extensions are injected, but m2e does not implement full
maven build lifecycle inside workspace (does not really make sense) and
not all build extensions get a chance to do their thing.

Assuming you are still talking about a build extension that provides
AbstractMavenLifecycleParticipant implementation to inject additional
dependencies, you should be able to invoke this implementation using
ILifecycleMapping2 and a subclass of DefaultMavenDependencyResolver,
which will lookup required component(s) from the project realm and
execute them before delegating to m2e default dependency resolution
logic. Beware that I have not actually tried this, so m2e may need some
fixing to make this work.
