Artifactory plugin: java.lang.ClassNotFoundException: hudson.matrix.MatrixRun

XMLWordPrintable

      We handle several Jenkins instances and we updated them all from 2.46.2 to 2.121.2. The plugins were also updated immediately afterwards. *

      The Artifactory plugin, specifically, was updated from 2.13.0 to 2.16.0.

      After that, the UI job configuration of Freestyle jobs AND the execution of pipelines jobs started throwing the following Exception:

Finished: FAILURE

      We tried uninstalling/installing/reinstalling the Matrix Project plugin. No success.

      Downgrading Artifactory back to the previous version "fixes" the issue.

      Then we noticed a pattern: the issue happens in instances where the Git plugin is not installed. Installing the Git plugin in the faulty instances would "fix" them.

      ------

      The Artifactory pom file lists git as optional dependency. But we still do not understand how the absence of the Git plugin would cause a ClassNotFoundException related to hudson.matrix.MatrixRun.

      Artifactory does not declare any dependency to the Matrix Project plugin. So, we wonder whether it did become a hard dependency but no one detected it because... hey... git is a standard plugin nowadays....

      As mentioned above, having Artifactory + Matrix Project plugins installed still causes the issue. So we also wonder if the Artifactory plugin isn't – maybe – running with its own classloader somehow...

      Either way, making the Git plugin an explicit hard dependency of Artifactory should solve the issue....

       

      * Side-note: We tell the Jenkins admins to update their stuff more often to avoid those big-bang updates. Next time we will chop fingers off...
