Problem description

Hello, I'd like to trigger a job on Accepted Merge Request Events and Closed Merge Request Events. Accepted Merge Request Events correctly trigger the job but that's not the case for Closed Merge Request Events: the webhook is correctly sent by Gitlab, Jenkins answers with a 200 status code but does nothing.

[jdillard]

Have you checked the Jenkins log for the Gitlab plugin, in Jenkins > System Log > Gitlab plugin?

[scramboy]

Experiencing the same issue here, and the log in Jenkins is the same as @dsiragusa provided, i.e. no further log after MergeRequestBuildAction. This feels like the logic did not go beyond the isAllowedByConfig check in isExecutable function of MergeRequestHookTriggerHandlerImpl, and looking at the object_attributes in webhook payload, the action is close, so would the issue be related to that the Action model defines closed instead of close?

[scramboy]

In addition to the above observation, should the close action be part of the skipBuiltYetCheckActions list? My personal guess is that users triggering job execution on close action would very likely have done a 'prebuild merge' in the merge action already. This would cause job execution of close action to be skipped.

Still an issue 2 years later. Are there no plans for this to be fixed?

[shurkanTwo]

I am having the same issue.

Same issue here..

I've tried to enable this setting, and it worked

Approved Merge Requests (EE-only)

[briantist]

Can confirm that Approved Merge Requests (EE-only) works to allow closed events to trigger (unintuitively).

Unfortunately, this also makes "Approve" events trigger the job (but not revoking Approval for some reason), and this is undesirable.

And while the plugin does know the state change because GitLab sends it in the webhook, the plugin does not expose it to the pipeline in any variable.

Thus, a job triggered by an Approval looks identical to a job triggered by the MR being (re)opened, or a new commit being pushed, etc. Would prefer a way to trigger the job on closed/merged events without also triggering on Approval, but even if we wanted to check this in the job itself, there's no way to determine that the job was triggered by an approval vs. another event.

Additionally, the triggerOnlyIfNewCommitsPushed: true does affect close/(re)open events, and they won't trigger if this is set, however, it does not affect the Approved event at all. This is frustratingly inconsistent, and if anything it's the opposite effect of what I actually want.
