something with maven itself, probably only fixable by upgrading to newer futur version.

duplicate of issue 158401, see there for the relevant maven issue.

will only be fixable after upgrading maven embedder binary to future 3.x version..

the fix/workaround in your projects is to define groupId of your project properly.
