NPE during Jenkins startup

    • jenkins 2.46 , splunk plugin 1.5.3

      Splunk plugin blocked Jenkins startup due to NPE. Am not what caused this though.

      Marking this as critical since this is blocking Jenkins startup i.e. when accessing jenkins home all we see is below NPE exception.

      I changed value of enabled to 'false' @ <jenkins_home>/com.splunk.splunkjenkins.SplunkJenkinsInstallation.xml to bring back jenkins.

       

      Below is stacktrace

          Hello,

          It happens also with 1.6.0 version of splunk plugin and jenkins version 2.7.4.

          Thank you,

          Alex

          We encountered this too but as we had multiple Jenkinses and not all suffered the NPE we were able to track it down to an extra newline in the <scriptContent> tag in the com.splunk.splunkjenkins.SplunkJenkinsInstallation.xml file. You can see the extra newline in the GUI too if you go to "Manage Jenkins", "Configure System", "Splunk for Jenkins Configuration",  "Advanced..." and " Customize Event Processing Command".

          So apparently 1.6.0 version can't handle empty lines in the scriptContent in the config whereas 1.5.2 could. For 1.5.3 I had to remove the whole scriptContent tag.

          When diffing the plugin code it seems like handling of legacy config was removed in 1.5.3.

          Same thing is happening to me on Jenkins 2.83, plugin version 1.5.3 or 1.6.0

          For anyone else troubleshooting this, the com.splunk.splunkjenkins.SplunkJenkinsInstallation.xml file is in the Jenkins home directory.
