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" ...

Log 3) Request X-GitHub-Event: push Payload .... "ref": "refs/heads/feature/update-gitignore" ...

UPDATE

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

Solution 1

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.

Solution 2

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.

I have "GitHub plugin" installed and used ${sha1} for Branch Specifier but no luck.

Hmm that`s strange. Pull builds should disabled and branch build should start. Could your show settings screen?

Please see images above.

Fine! This is two different process build on pull request and build in branch change. We create two different builds and check "request scm on changes" or something like this
