Thanks, this looks good overall. mvnd is registered as a commandlet, the NLS/help text is present, the shared MavenCommandlet extraction looks reasonable, and the full test suite passes locally for me.

I ran:

mvn clean test

I left one inline comment about the mvnd dependency metadata. I think this should be fixed before merging, because Java is currently not ensured as a dependency for mvnd 1.0.6.

Two smaller follow-ups:

• The test fixture should probably use MVND_VERSION=1.0.6 instead of MVN_VERSION=1.0.6.
• The testing instructions contain small copy/paste issues: mvnd--help should probably be mvnd --help.
