Fred Bricon commented on JBIDE-14396:
-------------------------------------

For the moment, the m2e-forge plugin I hacked has no official support anywhere. That was a quick'n dirty workaround for your issue.
We *may* be able to have m2e discover such a plugin if, for instance, it was mapped to the forge-maven-plugin AND some forge-maven-plugin goal was participating to an [interesting maven execution phase|https://docs.sonatype.org/display/M2ECLIPSE/Project+build+lifecycle+mapping#Projectbuildlifecyclemapping-Introducenotionsof%22interesting%22and%22notinteresting%22mojoexecutions]

> This can be solved by manually adding required projects in the workspace as classpath dependencies of the JUnit launch configured for the project being tested, but this is obviously not right, and should be configured automatically by the M2E integration.
