When run via timers or Github pull requests (SCM triggers), Jenkins fails intermittently about 50% of the time with a java.io.Exception while attempting to parse the Git changelog.
The same job runs fine when triggered manually.

[JENKINS-48608] NPE when empty JIRA site is saved
That's interesting, do you have a JIRA site configured and working in other builds?
Anupam Sengupta
added a comment - Not really. We do use JIRA, but JIRA is currently not configured in this particular Jenkins instance for any build.

Anupam Sengupta
added a comment - warden, I have now deleted the JIRA config block in the system settings. The build when triggered manually works fine, but will wait and confirm back tomorrow on the scheduled build status (as that is the one which was failing till now).

added a comment - warden, the nightly build on schedule also ran fine after the deletion of the empty JIRA block.
So looks like that was the failure cause. Thanks for the pointer in resolving the issue.

Based on that stack trace element at JiraSite line 289, I suspect this is an issue with the Jira plugin, not with the git plugin.
