We have a multibranch pipeline job set up to scan a git repo (which
contains Jenkinsfile at its root) for branches and create branch-specific
jobs for each branch discovered. The Jenkinsfile on a branch specifies:
triggers {
cron('@midnight')
}
and this indeed runs nightly at midnight. However, when I delete the above
block and commit the Jenkinsfile to my branch, it appears to have no
effect. Last night the build still ran at midnight. This is my problem.
I confirmed the change by looking on the branch job configuration page and
indeed see an empty BuildTriggers section. There are no triggers specified
and none of the trigger checkboxes are checked.
Please confirm whether this is indeed the way I am supposed to disable a
trigger specified in a multibranch pipeline Jenkinsfile.
Also, note that in the top-level pipeline job configuration, BranchSources
is set up so "All branches get same properties" and set the property
"Suppress Automatic SCM Triggering" because we only want builds to be done
nightly for now, and not as a result of commits. Also, "Scan Multibranch
Pipeline Triggers" is configured to scan our repo every minute for branch
changes. I assume this means that it also scans and applies any changes to
Jenkinsfiles (e.g. our trigger {} changes) to the branch job. I believe
this to be happening, bc as I've said, the job configuration page seems to
have reflected our change to the Jenkinsfile in SCM. But the build still
was triggered last night at midnight.
Please let me know if you know what's going wrong here, or have any
suggestions for troubleshooting this.
Thanks,
Tim
