NPE from support core plugin attaching bundle

XMLWordPrintable

      I encountered a support core null pointer exception while evaluating other things.

      The null pointer exception stack trace was:

          markewaite What version of support-core are you running ? I am pretty sure this is fixed in version 2.58, addressed by JENKINS-57602.

          As far as I can tell, I'm running support-core plugin 2.56 as contained in CJD 2.176.2.3 release 2.

          allan_burdajewicz I was preparing for a Jenkins World 2019 talk on Docker and Jenkins [as code] and found it while working on a pull request based on https://github.com/cloudbees-oss/cjd-jcasc-demo/tree/8909603c0befb598d90e5e1c316354040a5552eb . I was running in a Docker container using Docker for Windows (Linux container running on a Windows computer) using the changes in my proposed pull request https://github.com/cloudbees-oss/cjd-jcasc-demo/pull/9 .

          During startup, the console output reports that null pointer exception.

          CJD 2.176.2.3 ships with 2.56 indeed. So I assume this is fixed in 2.58. Let me try to reproduce the issue to confirm that.

          Confirmed that:

          Note: The remote FS is a mandatory field field in the UI but for not from JCasC. Although resiliency has been added to the support-core plugin in that regards, this could well be a bug with JCasC as suggested in https://github.com/jenkinsci/support-core-plugin/pull/179#issuecomment-510910195 ?

          Allan BURDAJEWICZ added a comment - Confirmed that: this is caused by the missing remoteFS for those 2 agents: https://github.com/cloudbees-oss/cjd-jcasc-demo/blob/1.3/jenkins.yaml#L82-L107 support-core:2.58 fixes this Note: The remote FS is a mandatory field field in the UI but for not from JCasC.
