@tpbradt I was about to write a different reply, but I realized I'm not positive I understand what config you have set up for the plugin. Can you please attach a screenshot of the Jenkins job config where the plugin is configured?

@tpbradt you will need to add the screenshot via the GitHub issue web page, not replying to the email.

Done. Edited original comment above.

@tpbradt and what URL are you using for the webhook on the GitLab side, to trigger this build?

http://devbld:(key)@jenkins.ops.cld/project/fe/mr/app-pld

...with the key masked out. Just to make it clear, we have our own gitlab locally.

@tpbradt if you're still having this issue, can you follow the instructions in the User Support part of the README and attach logs from the plugin when you see a rebuild that should not happen?

Here is a log from me reproducing just now. We have done some updates recently to our tools:
Gitlab plugin version: 1.5.3
Gitlab version: 10.5.4-ee
Jenkins version: 2.110

rebuild.log

(Job config screenshot visible)

@tpbradt I can reproduce this. I'll see if I can figure out what the problem is. But I'm surprised no one else has seen it.

@tpbradt what events have you set up in the webhook configuration in GitLab? Pushes and/or Merge Requests?

Is there a workaround for this? Both "Never" and "Push to Source Branch" options for "Rebuild Open Merge Requests" do not work.

@mmehra can you show me your webhook configuration from GitLab? Have you set up hooks for both pushes and MRs, or just MRs? Please follow the instructions in the User Support section of the README to increase debug logging for the plugin, and then attach those logs after you reproduce this issue.

I realize this is somewhat of a thread hijack, but I am hitting the same issue as @mmehra: rebuilds are not happening at all: I have tried
Rebuild open Merge Requests: On push to source branch
and
Rebuild open Merge Requests: On push to source or target branch

I have not tried pushing to the target branch to see if that triggers, but but pushes to the source branch do not trigger builds.

This is version 1.5.9 of the gitlab plugin, and version 2.141 of Jenkins.

@omehegan Just figured out the issue (in my case).

These triggered builds:

• Build trigger on merge request creation
• Build trigger on merge request comment
  This did not:
• Build trigger on new push to existing open merge request.

I looked at my config again, and realized I had it set to ignore WIP merge requests (which I was using since it was a test MR). So, now the bug is: why is it triggering builds on create and note when "ignore" is checked. :)

@jkugler how were you marking the MRs as being WIP?

@omehegan The subject started with WIP: per the GitLab convention. i.e. https://docs.gitlab.com/ee/user/project/merge_requests/work_in_progress_merge_requests.html

Hello,

i read through this issue and issue #636. However I don't seem to find a solution for my problem.

Versions:

• GitLab Plugin Version 1.5.9 (aso tested Version 1.5.10)

• GitLab Community Edition 11.03

• Jenkins Version 2.121.2

Jenkins Trigger Config:

• Push Event (for commiting on source branch without having created an MR; not necessary!!!)

• Opened Merge Request Events (for creating an MR)

• Rebuild open Merge Requests: On push to source or target branch (for pushing on an open MR/ merging MR)
  (I actually activated all triggers, but would logically just need those.)

GitLab Webhooks

• Push Events

• Merge Requests Events

What I want to do:
I'm working with a Jenkins pipeline and would like it to be triggered when creating an MR, pushing on an open MR, merging the MR (and ideally when commiting on source branch without having created an MR before; not required tho).

What happens:
The Push Event (triggerAcionType: PUSH) triggers whenever Im commiting on the source branch (with and without open MR) and when I merge my source branch into master (with and without open MR).
Creating a merge request (triggerAcionType: MERGE) on GitLab triggers the pipeline as well. Commiting on an open MR (triggerAcionType: MERGE) triggers the pipeline too, using the described trigger configuation. However as I'm using Push Events too, I have two Pipelines getting triggered. That blocks Jenkins unnecessarily. Merging the MR doesnt trigger the pipeline with following message:

Last commit in Merge Request has already been built in build #251

Result:
I would like to just use the MR triggeres, as I dont necessarily need to build without having a MR opened and having two Pipelines triggered is not sufficient. However the MR Event doesn't trigger when merging.

Question:

• Is there a workaround to trigger the merge with a MR (triggerAcionType: MERGE)?
• Would a merge of a MR build the master (like the Push Event) or just rebuild the source branch? That' s how I understand the log message that I quoted above.

Thank you and please let me know, if Im missing Information, logs.

Do we have any updates? I got the same problem and its very important for us because "when build job" configuration is the main idea of plugin.

@tpbradt what events have you set up in the webhook configuration in GitLab? Pushes and/or Merge Requests?

@omehegan Sorry I never got back to you. We trigger webhooks on merge request only.

Look like I get this problem when json include "state" : "opened" and "action" : "update" with TriggerOpenMergeRequest.never

I found the code which do this bug. On my jenkins I installed snapshot version and if you wanna, after some time, I can create Merge Request for project.
p.s. I'm not sure that all my changes was correctly, but this bug is resolved into my snapshot.

I have built a snapshot with the change from #869 which should fix the issue of builds getting triggered even when "Rebuild open merge requests" is set to "Never." For those affected by that issue, please try this and let us know if it fixes the problem. http://repo.jenkins-ci.org/snapshots/org/jenkins-ci/plugins/gitlab-plugin/1.5.12-SNAPSHOT/gitlab-plugin-1.5.12-20181217.052605-2.hpi

@GoWithTheFlo95 it sounds like your issue would be resolved if we fix #636. Do you agree?

@omehegan Just tried the build you provided 2 days ago and I can confirm it fixes the issue for me

@omehegan sorry for the late Reply, but yes this would fix my problem.

@omehegan Any update on when the fix will be merged ?

I'm experience the same issue when Accept the merge on GitLab, it is not trigger a new job on jenkins I'm using gitlab 12.5.8 jenkins 2.229 git plugin 4.2.2 gitlab_plugin 1.5.13

Do you have any idea about when it will be solved ?

Hi
Any plan to finish and release this fix?
