sthomps,
What base Eclipse install are you using – is it STS4, or have you installed STS4 into Eclipse? I ask because this isn’t one of our CodeMix processes and looks like it’s part of the newer versions of Spring Tool Suite. It would also be strange to have this show only if CodeMix is enabled, quite sure that would be running regardless of CodeMix status, but this is something we can check.
When you say “building Maven projects”, do you mean a maven based build initiated through Eclipse, or them being built by/within the IDE? I’m assuming the latter, but would like to be sure.
