For anyone trying to build Hawkular and running into checkstyle issues
despite adding -Dcheckstyle.skip to the mvn command line, you may need
to add this as well to make sure it makes it to the recursive builds...
mvn blahblah '-Dsrcdeps.forwardProperties=srcdeps.*,revapi.skip
-Dcheckstyle.skip'
p.s. the revapi.skip is not relevant to checkstyle but if you happen to
hit a revapi issue it may help you out.
