FWIW, I have encountered similar symptons with 0.21.0 on a build that
was fine with 0.20.0.

Nuking the local Maven repository fixed this issue, however. One
explanation for this might be a change in the metadata artifact's format
Tycho installs below ~/.m2/repository/p2, but that's just a wild guess.

Aside from that minor hiccup, Tycho 0.21.0 works fine (tested on Eclipse
Code Recommenders and a commercial project).

Best wishes,

Andreas
