[JIRA] [scripttrigger] (JENKINS-17566) Severe polling error when using script trigger

Sun, 05 May 2013 11:28:00 -0700

Hi,

I checked the new version. The trigger now definitely runs on the master, the corresponding messages are printed. But it still ends with "[ERROR] - Polling error", unfortunately it prints neither the exception or the stack trace to the log.

I then reviewed the xtrigger source code and noticed that the method that prints the stack trace is only printing the Exception message and the stack trace goes to System.err.

I then opened the servlet container's (winstones) output and found the root cause:

java.lang.NullPointerException
        at org.jenkinsci.lib.envinject.service.EnvVarsResolver.gatherEnvVarsNode(EnvVarsResolver.java:160)
        at org.jenkinsci.lib.envinject.service.EnvVarsResolver.getDefaultEnvVarsJob(EnvVarsResolver.java:89)
        at org.jenkinsci.lib.envinject.service.EnvVarsResolver.getEnVars(EnvVarsResolver.java:68)
        at org.jenkinsci.lib.envinject.service.EnvVarsResolver.getPollingEnvVars(EnvVarsResolver.java:36)
        at org.jenkinsci.plugins.scripttrigger.groovy.GroovyScriptTrigger.checkIfModified(GroovyScriptTrigger.java:140)
        at org.jenkinsci.lib.xtrigger.AbstractTrigger$Runner.run(AbstractTrigger.java:198)
        at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145)
        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
        at java.lang.Thread.run(Thread.java:722)



So the following things have to be checked:


    
	
  • What causes the NPE (maybe the EnvVarsResolver also uses the Node, which is offline). I run the script as system script - why is any node environment involved?
    • 
	
  • Fix the logging in the XTrigger lib to be more informative on unexpected Exceptions.
    •
