Added as a maven dependency to java-overlay
This was added to the tree a couple of years ago by ercpe. Unfortunately 2.2.3 was added with SLOT 0 when 1.2 in the overlay also uses this SLOT. I doubt they are compatible. The overlay only uses this for ancient Maven stuff that no one in their right mind would use now. All that will need to get cleaned up sooner or later but I'll close this now.
