I'm seeing the following exception in my jenkins log:
WARNING: hudson.triggers.TimerTrigger.run() failed for hudson.model.FreeStyleProject@3bb09a54[Test] java.lang.NullPointerException at hudson.triggers.TimerTrigger.run(TimerTrigger.java:55) at hudson.triggers.Trigger.checkTriggers(Trigger.java:283) at hudson.triggers.Trigger$Cron.doRun(Trigger.java:217) at hudson.triggers.SafeTimerTask.run(SafeTimerTask.java:51) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
I have been able to reproduce this by creating a new job in the disabled state. Waiting for a normal execution period to pass, then re-enabling the job. Each time the trigger fails until I re-save the project, then appears to trigger properly.
My project config is the following:
