At line 651, the > call to 'workingDirectory(workspace)' returns null - because null was passed > in as a param from AbstractProject. This means that at line 657, the call to > !!workingDirectory.exists() results in a null pointer. > Suggested fix: remove the remotePoll, or make it require a workspace to do > the polling. > Stacktrace: > Sep 2, 2011 2:41:50 PM hudson.triggers.SCMTrigger$Runner runPolling > SEVERE: Failed to record SCM polling > java.lang.NullPointerException > at hudson.plugins.git.GitSCM.compareRemoteRevisionWith(GitSCM.java:657) > at hudson.scm.SCM._compareRemoteRevisionWith(SCM.java:354) > at hudson.scm.SCM.poll(SCM.java:371) > at hudson.model.AbstractProject.poll(AbstractProject.java:1305) > at hudson.triggers.SCMTrigger$Runner.runPolling(SCMTrigger.java:420) > at hudson.triggers.SCMTrigger$Runner.run(SCMTrigger.java:449) > at hudson.triggers.SCMTrigger.run(SCMTrigger.java:103) > at hudson.triggers.SCMTrigger.run(SCMTrigger.java:83) > at hudson.triggers.Trigger$1.run(Trigger.java:229) > at hudson.DependencyRunner.run(DependencyRunner.java:73) > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) > at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:303) > at java.util.concurrent.FutureTask.run(FutureTask.java:138) > at > java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) > at java.lang.Thread.run(Thread.java:662) -- This message is automatically generated by JIRA.
