java.lang.NullPointerException

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • I have a matrix based security setup where "authenticated" can do everything and anonymous can do nothing. In addition, I am using the template-project-plugin. In such a configuration polling the SCM will fail due to Hudson.getItem() returning {{null}}. The reason for that is that the authentication of the {{SCMTrigger.run}} method is null and therefore, jenkins assumes that this user is unauthenticated (anonymous) and therefore, does not have any permissions whatsoever. {noformat} ERROR: Failed to record SCM polling for java.lang.NullPointerException: project is null, at hudson.plugins.templateproject.ProxySCM.requiresWorkspaceForPolling(ProxySCM.java:179) at hudson.model.AbstractProject._poll(AbstractProject.java:1417) at hudson.model.AbstractProject.poll(AbstractProject.java:1387) at hudson.triggers.SCMTrigger$Runner.runPolling(SCMTrigger.java:420) at hudson.triggers.SCMTrigger$Runner.run(SCMTrigger.java:449) at hudson.util.SequentialExecutionQueue$QueueEntry.run(SequentialExecutionQueue.java:118) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) {noformat} Whether this is a bug in ProxySCM (and therefore the template plugin) or whether this is a general problem is hard for me to tell. I was able to work around the problem by giving "Job/read" permission to "anonymous" but IMHO the SCMTrigger should run as SYSTEM.
