Despite not listing Maven as a dependency, Gerrit Trigger depends on the Maven Integration plugin.

When I disable the Maven Integration plugin, Jenkins still triggers on a new Gerrit patch set, but when the build is done, Jenkins fails to report back to Gerrit with the following error message:

INFO: SpECTRE_simple_Gerrit #3 main build action completed: SUCCESS

When I enable the Maven Integration plugin, Gerrit Trigger works perfectly and reports back to Gerrit.
