Mickael switched the parent pom over to use Tycho 0.15.0 (which is in staging and should hit Maven Central later this week [1]). I've rebuilt [2] the version we have in the snapshots repo [3], so builds should all be good to use this updated pom. Note too that both the parent pom and target platform pom are now versioned 3.4.0.M1-SNAPSHOT in trunk. ** If you get a class cast exception running a build, it's because of this change. Rebuild your local copy of the parent pom and try again. ** -- Mickael, please don't apply this change to the 3.3.x branch yet. If we have a need to do so, we can, but IMHO we should just leave branch to minimal changes right now.
