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.
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)
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.
