See, for example: https://builds.apache.org/job/beam_PreCommit_MavenVerify/2530/ The list of modules is mostly grey (didn't run).
Some of these are modules that once existed, but have since been refactored away. Others were introduced in a pull request but were never actually committed. (e.g., the nicely typo'ed Apache Beam :: SDKs :: Java :: Microbenchamkrs) Google tells me I should be able to "Delete all disabled modules" ( https://issues.jenkins-ci.org/browse/JENKINS-4561), but I can't find that command. I *can* do things like configure PostCommits, etc. Am I missing something obvious? Thanks, Dan
