Finished: FAILURE

Job definition is included as config.xml

I'm reasonably confident this was working correctly before I upgraded to GitHub Branch Source Plugin 2.5.3, but it may not have been checked for several weeks. Thus, it could have been broken by an earlier change, not specific to 2.5.3.

The job requires credentials and is part of a Docker image definition that I use for testing.  I can share temporary access to that repository with one or two others if necessary.

As far as I can tell, the same problem is also visible in GitHub Branch Source 2.5.1 and 2.5.2.

GitHub Branch Source Git plugin 2 4 . 5.3 0 pre-release reports a class cast exception when scanning in a multibranch pipeline definition for the hello-world-plugin.
I'm reasonably confident this The code that is throwing that exception was working correctly before I upgraded to GitHub Branch Source Plugin 2 added in [089a6ec|https://github . 5 com/jenkinsci/git-plugin/pull/696/commits/089a6ecf41c5a928dc78ecfc1024ad2029955afe] as part of [pull request 696|https://github . 3, but it may not have been checked for several weeks com/jenkinsci/git-plugin/pull/696] .   Thus, it could have been broken by an earlier change, not specific   I suspect that more logic is needed in [this line|https://github.com/jenkinsci/git-plugin/pull/696/commits/089a6ecf41c5a928dc78ecfc1024ad2029955afe#diff-8dfe27475624ffa72985974b8348bffdR54] to 2 check that the passed in SCMSourceContext is a GitSCMSourceContext before setting the pruneRefs value . 5.3.

The job requires credentials and is part of a Docker image definition that I use for testing.  I can share temporary access to that repository with one or two others if necessary.

As far as I can tell, The failure does not seem to be related to the same problem is also visible in GitHub Branch Source 2 plugin . 5.1 and 2.5.2.
