Jenkins / JENKINS-57397 Jenkins Build fails with “java.lang.NullPointerException”

Issue Type: Bug Assignee: Adharsh M Components: git-plugin, pipeline Created: 2019-05-10 09:29 Priority: Minor Reporter: Adharsh M   We have integrated Jenkins with Github to build jobs as and when PR is raised with the github pull request builder plugin. From yesterday when the job gets triggered we are seeing this failure "java.lang.NullPointerException" even before the pipeline starts to execute and the job reports the status to github as failed. Also in the console there is a log that mentions "Resuming build after jenkins restart" but there was no restart at the time when this job was triggered But in a little while the job starts executing and then passed the build again in jenkins? This happens often if we retrigger the job but not always!!! Any idea on why this is happening   Jenkins Console: Resuming build at Thu May 09 16:30:11 UTC 2019 after Jenkins restart [Pipeline] End of Pipeline Setting status of b9d1bd39cfae59d607b1a8060f2a8ae2fc180a1e to FAILURE with url https://JENKINS_URL/job/JOB_NAME/103/ and message: 'Build finished. ' java.lang.NullPointerException Finished: FAILURE

Re: Jenkins Build fails with “java.lang.NullPointerException” There aren't enough instructions for me to duplicate the problem and the null pointer exception stack trace is not included. Please check the Jenkins log and other locations to see if you can find the full stack trace.

Re: Jenkins Build fails with “java.lang.NullPointerException” We need either enough instructions to duplicate the problem or enough stack traces to identify the problem without duplicating it. Since the git plugin does not suppress exceptions, I'm reasonably confident that the issue is not in the git plugin. I suspect the exception is being thrown in the workflow CPS global lib plugin. That is the plugin which handles pipeline shared libraries. Have you made recent changes in the pipeline shared libraries that you are using? For example, if one of the shared libraries is causing a null pointer exception in its own code, that might cause the type of message you're seeing. I'll assign this to workflow-cps-global-lib plugin as a possible place for further investigation.
