Subject Re: Problems building the current master

Probably all Flink dev's have the "flink-compiler" jar in their local ".m2"
directory.
Also on travis, we are caching the ".m2" directory to improve build times.
Maybe it would make sense to disable that on travis to detect those issues
in the future.
I'll try it out to see how it affects the build time.
