Maven does not work with the new p2 repository

[Gabor Szarnyas]

For some strange reason, the p2 repository does not work from Maven. I noticed that you published a new version of EMFJson (ghillairet/p2@7d5c122), and this replaced the (compositeContent|compositeArtifacts).xml files with (compositeContent|compositeArtifacts).jar files (which contain the respective XML files). The JAR files seem fine and the repository contains dependencies required for building EMFTriple. However, Maven throws the following exception while building EMFTriple:

I tried it with both Maven 3.0.5 and 3.3.9.

The repository has been fixed.
