Jenkins won't trigger build after merging a pull request in GitHub

Question

So far triggering a build in Jenkins work's fine for creating a new pull request, pushing changes and leaving a comment like test this please however, when I hit green "Merge pull request" button in GitHub, I don't see any jobs running in Jenkins.

MY JOB SETTINGS

Refspec: +refs/pull/*:refs/remotes/origin/pr/*

Branch Specifier: origin/master or ${sha1}

Took [GitHub pull request builder plugin documentation][1] as reference.

GITHUB WEBHOOK LOGS

Log 1) Request X-GitHub-Event: pull_request Payload .... "action": "closed" ...

Log 2) Request X-GitHub-Event: push Payload .... "ref": "refs/heads/develop" ...

UPDATE

I have Pull request, Issue comment and Push events are enabled in GitHub Webhook Setting page.

Answer 1

Merge should be part of a regular push changed request and might not be handled by Pull Request Builder plugin but rather standard github plugin (as it is not a pull request anymore).

I don't know what type of job you are using (pipeline, DSL, ...), but ...

From your logs, I can tell that you have different branches where you push changes on merge, they are "develop" and "feature" while in branch specifier you have origin/master, so it will ignore changes to any of the other branches.

Answer 2

I had to create two different items. One for pull request builder and another for pull request merger.

Whole example/answer is here: Setup GitHub and Jenkins integration for pull request builder and merger

The difference is explained under bullet point 13 and 14. 14. Configure Jenkins project - Nation-Merge is the one solved my problem.

• Refspec is blank.
• Type origin/develop in "Branch Specifier" field.
• Tick "GitHub hook trigger for GITScm polling" option.
