Hello,

I'm having a problem that seems pretty much identical to this one for the Gitlab Branch Source Plugin: https://github.com/Argelbargel/gitlab-branch-source-plugin/issues/45

I'm assuming the root issue is very similar, if not identical. On Github webhook triggers a number of branch indexing jobs are kicked off for builds in the current repo, as well as for other repos. I'm using BlueOcean.

Questions:

1) Is this a known issue?

2) Is there a workaround?

3) As a possible means to come up with a workaround, are there any variables I can latch onto that would give me visibility into the context so in my Jenkinsfile pipeline I can do the following on branch indexing:

currentBuild.result = 'NOT_BUILT'
error('Aborting build triggered by scan process')

This was a suggestion in the above Gitlab thread, only I'm not seeing an equivalent to `gitlabActionType` in the list of environment variables (output with "env"). It would be great if I could ignore builds from branch indexing as a short term workaround without disabling the webhooks entirely.
