These docs state that Guice Modules annotated with @Named will be loaded and configured automatically by Sisu. I think the actual loading is done by org.eclipse.sisu.space.QualifiedTypeBinder but it only seems to work when running tests via the maven-plugin-testing-harness and not when actually running the plugin.
I've tried to add various different artifacts to compilation including sisu.inject, sisu.inject.extender and plexus-container-default but cannot get the Modules to be loaded, and consequently the Mojo fails to instantiate with com.google.inject.ProvisionException: Unable to provision
I'm working on a simple project to reproduce, I'll update the ticket with a link to it. If I can provide more information, or if I'm just missing something simple please let me know. Thanks
