the redirection was not handled correctly, making maven go completely
crazy. Somehow eclipse did not complain too much, but building on the
command line was a nightmare, and the build server is under heavy
thunderstorm since a while now, with roughly half the playgrounds not
compiling.
This fix, together with cleaning my local ~/.m2/ repo, solved the problem
on my machine.
Hopefully the same happens automatically on the build server. If not,
deleting the ~/.m2/ of the server manually should do the trick.
