Crash due to wrong guava version

kie-services relies on guava 15.0 due to its dependency on "reflections0.9.10".
This results in the error listed below. It can be worked around by adding a dependency in your pom to use guava 10.0.1 (required by "sisu.plexus" but omitted). This removes version 15.0 from the deployment. I haven't experienced any issues so far but this might lead to other problems.
