Pipeline P4_CHANGELIST populated from Jenkinsfile changelist, not from repo p4sync mappings in Jenkinsfile

      I am noticing an odd issue where our P4_CHANGELIST number is populated per the last set of changes to the Jenkinfs file, but not for any 'p4sync' calls in the Jenkinsfile itself.

      As an example, here's the initial Jenkinsfile sync snippet, notice the changelist "961423". From here on out, the P4_CHANGELIST variable will have that as it's changelist number.

      [... snip ...]
P4 Task: reverting all pending and shelved revisions.
... p4 revert /home/jenkins/jobs/build-tip/workspace%40script/... +
... rm [abandoned files]

... p4 sync /home/jenkins/jobs/build-tip/workspace%40script/...#none +
... rm -rf /home/jenkins/jobs/build-tip/workspace%40script

P4 Task: syncing files at change: 961423
... p4 sync -p /home/jenkins/jobs/build-tip/workspace%40script/...@961423 +

P4 Task: saving built changes.

... p4 client -o jenkins-build-tip +
... p4 info +

... p4 info +
... done
[... snip ...]

      A little farther in my build, I have my actual repo mappings. Here's the sync log from it:

      [... snip ...]

[... snip ...]

      In the case above, I would expect P4_CHANGELIST to be 968942, as it is the newest changelist for the repo at that point in the Jenkinsfile. If I were to have a workflow step right after my p4sync call that did something like this:

      sh "echo ${env.P4_CHANGELIST}"

      I would want the output to be '968942', but right now, it outputs '961423'.
