Minor We were using the ability to trigger a pipeline job from the completion of a Freestyle job.
This worked on 2.43.1, but broke on 2.43.2. We upgraded to 2.43.3, just to make sure the problem was still there, and it is.
In the Logs, we get the following error / stacktrace when the Freestyle build that should trigger the Pipeline build completes:
May 27, 2017 8:57:33 PM WARNING hudson.model.listeners.RunListener report RunListener failed java.lang.NullPointerException at hudson.model.Result.isBetterOrEqualTo(Result.java:130) at jenkins.triggers.ReverseBuildTrigger.shouldTrigger(ReverseBuildTrigger.java:158) at jenkins.triggers.ReverseBuildTrigger.access$000(ReverseBuildTrigger.java:90) at jenkins.triggers.ReverseBuildTrigger$RunListenerImpl.onCompleted(ReverseBuildTrigger.java:277) at hudson.model.listeners.RunListener.fireCompleted(RunListener.java:211) at hudson.model.Run.execute(Run.java:1773) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:43) at hudson.model.ResourceController.execute(ResourceController.java:98) at hudson.model.Executor.run(Executor.java:405)
We are aware that Freestyle builds can not trigger upstream Pipeline builds, but Pipeline builds used to be able to be triggered by defining "Build after other project completes – and it is that functionality that is now an issue in Jenkins Core 2.43.2 and higher in the LTS series.
