Fixed synchronization issue.
Adding travis-ci configuration
Specify source, and target for maven build. Seems necessary
to build on travis-ci.org.
Reduce build platforms
It might help if I put the target and source version in the
compiler plugin configuration section...
Travis CI build failing in the gpg signing phase. This should
hopefully prevent it from executing that phase.
Update test data with correct hash and metadata information. This should
also make sure the build will pass.
