How to trigger jenkins build upon bitbucket pull request merged - jenkins

I looked at all other related questions and answers, didn't find anything solid, hence I'm opening a new question to look for your kind help, I've been working on this the whole day, any help I can get would be highly appreciated.
Here's my environment:
self-hosted jenkins server (Jenkins ver. 1.651.3) with git and bitbucket plugin installed.
https://bitbucket.org (I do not have a self-hosted bitbucket server)
What I want to do: to trigger jenkins build upon pull request got merged from feature branch to master branch.
Different setting combinations which I had tried:
jenkins: 'Build when a change is pushed to BitBucket' checked.
bitbucket: web hooks trigger: 'Repository push' checked.
Result: build was triggered successfully upon commit to master branch, but that's not what I want, but at least I know the communication between my jenkins server and bitbucket is fine.
jenkins: 'Build when a change is pushed to BitBucket' checked.
bitbucket: web hooks trigger: 'Repository push' checked, and Pull Request - 'Merged' checked.
Result: jenkins does not respond to the pull request merged action. I assumed it would work since I had the Pull Requst - 'Merged' checked in the web hooks trigger setting, and I did see the request was sent by bitbucket to my jenkins server, and it got 200 status code back from my jenkins server, but still, nothing happens.
jenkins: 'Build when a change is pushed to BitBucket' checked. And besides that, I installed another plugin called bitbucket-pullrequest-builder-plugin, and configured it according to the instruction.
bitbucket: web hooks trigger: 'Repository push' checked, and Pull Request - 'Merged' checked.
Result: with the help of bitbucket-pullrequest-builder-plugin, the build was indeed triggered upon pull request created. But the jenkins server polls the bitbucket repository constantly, and I didn't find a way to stop that, no way to trigger build ONLY upon merge neither...
I heard there's people says that you'll need to install a post-hook plugin on the bitbucket server in order to do what I want to do, but the thing is I dont host the bitbucket...

Based on some research you can have a few options as of today Nov 12 of 2017:
Use the generic post webhooks plugin that supports pull request trigger. And from jenkins pick it up with the generic webhooks plugin, then maybe do a secondary trigger from jenkins.
Upgrade the bitbucket server and webhooks to jenkins plugin. The server 4.13 does not work well with later webhooks to jenkins plugin. A paid version of the plugin probably is your best choice.
Or try bamboo that comes with the "plan banches" feature.

When you configure GIT - push, commit... etc hooks, be sure to check the JENKINS git selection, and set the BRANCH to check for (** specifies all branches) and most importantly,
USE localtunnel.me or similar to set your JENKINS online or it won't work.

Bitbucket Server : Merge check - Minimum successful builds not enabling merge even after the condition is satisfied

I have configured Bitbucket Server to work with Jenkins by enabling a Webhook in Bitbucket with the Jenkins URL and the event being - Pull request approved. So I want a build on Jenkins to be triggered when a pull request is approved by the named reviewer.
The Jenkins job is configured to be triggered remotely using a token and that token is specified in the Bitbucket Webhook along with the Jenkins URL. This is working as expected. The Jenkins job is triggered automatically as soon as the pull request is approved by the reviewer.
But, I have also configured a merge check for the project . The merge check is enabled for minimum successful builds and the number of builds to be successful is configured to be 1. So, I expect the merge button to be enabled as the reviewer has approved the pull request and the Jenkins build has run (also success). But unfortunately, the merge button is not enabled even after all this. I also triggered a build manually on the same commit ( was success too ) but with no success on the merge button being enabled. Please help me out. Thanks.
I had the same problem and here are the steps of how I fixed it.
Use Bitbucket and not Git as the source code management. But, Bitbucket seems to be only avaiable when creating a Multibranch Pipeline.
Now, that you use Bitbucket, install plugin Bitbucket Branch Source Plugin
Bitbucket appears to get the result of the build from Bitbucket Branch Source plugin
The plugin requires some configuration, this webpage helped me a lot.
We had the same problem, if in your case you have at least one failed build before the succesfull one, then you will not be able to merge until you push a new code to the PR branch. This answer comes after discussing it with Bitbucket's support team.

Bitbucket webhook to trigger Jenkins job

I'm having trouble getting my webhook in bitbucket server to start a Jenkins job. I've read through the other answered questions on here and can't get it going.
Bitbucket setup:
No special plugins installed
In repository settings I have a webhook set up
URL: http://[my jenkins url]/bitbucket-hook/ (yes I have the trailing slash)
Repo Push event selected
Jenkins setup:
Bitbucket plugin installed
Created new job
Set SCM to Git and added repo details
Set branches to build to either ** or refs/heads/rob-jenkins (a branch in git)
Build when a change is pushed to bitbucket selected
What I do:
I make a change to a file in rob-jenkins branch, push and the job is not started in Jenkins.
What I see:
In bitbucket, repo settings, webhooks I can see the webhook fired as soon as the commit is pushed. It has a 200 http status code, response body is empty.
In Jenkins I've set up a logger for
com.cloudbees.jenkins.plugins.BitbucketHookReceiver
com.cloudbees.jenkins.plugins.BitbucketJobProbe
com.cloudbees.jenkins.plugins.BitbucketPayloadProcessor
com.cloudbees.jenkins.plugins.BitBucketTrigger
And when I look at those logs I can see only 1 entry from com.cloudbees.jenkins.plugins.BitbucketHookReceiver
Received commit hook notification : {"eventKey":"repo:refs_changed","date":"2018-05-22T12:18:11+1000","actor":{"name":"xxxxxx","emailAddress":"xxxxxx#xxxxxx.com","id":53,"displayName":"xxxxxx","active":true,"slug":"xxxxxxx","type":"NORMAL"},"repository":{"slug":"xxxxx","id":1,"name":"xxxxx","scmId":"git","state":"AVAILABLE","statusMessage":"Available","forkable":true,"project":{"key":"SS","id":2,"name":"xxxxx","description":"xxxxxx","public":false,"type":"NORMAL"},"public":false},"changes":[{"ref":{"id":"refs/heads/rob-jenkins","displayId":"rob-jenkins","type":"BRANCH"},"refId":"refs/heads/rob-jenkins","fromHash":"1d9ad42fa404c893853094b0072e5b839f787589","toHash":"9bf7dc873f355259e4338ee80afbd246ecbb48a9","type":"UPDATE"}]}
There are no other entries in the log.
In the job itself, the BitBucket Hook Log screen just says "Polling has not run yet."
No idea why it isn't triggering the Jenkins job... what am I missing?
I've tried setting the Poll SCM manually and that didn't make a difference.
I've done a manual build and it works fine
as commented by #tomas-bjerre the resolution was to use a different plugin
I would recommend using thie plugin instead: github.com/jenkinsci/generic-webhook-trigger-plugin – Tomas Bjerre yesterday
No plugin needed. Just add a post-recieve hook under your repo in Bitbucket. On Jenkins, under Build Triggers, Trigger builds remotely (e.g., from scripts) Trigger builds remotely (e.g., from scripts) and specify an Authentication Token. A bash or python script can be used for the hook. Anytime a git push is run (not just a commit), you trigger a build!

How can I get Jenkins builds to report failures back to Bitbucket server?

My work is running Jenkins and Bitbucket Server (so instead of the bitbucket cloud, they host their own bitbucket version). I am used to having passing/failing builds on github and bitbucket cloud immediately reporting back on PRs and branches as to whether the build passed or failed. I want to give that gift to my team in the current environment. How do I get PRs in Bitbucket server to receive success/failure of builds from Jenkins?
[Figure 1 just shows an example of the functionality I want, operational on PRs in github+codeship]
While the Webhook to Jenkins for Bitbucket can help notify Jenkins to poll whenever there is a commit, you still need to be mindful of the “lazy ref updates” in Bitbucket (described in this thread)
We had to implement something that would do a get to the REST API for the pull-request/*/changes before the call to the Jenkins /git/notifyCommit url.
The last Jenkins URL /git/notifyCommit comes from the Jenkins Git plugin.
See more at "Configuring Webhook To Jenkins for Bitbucket".
Once Jenkins is properly called, you can then, as mentioned in "Notify build status from Jenkins to Bitbucket Server", use the "Jenkins Stash Pullrequest Builder", from nemccarthy/stash-pullrequest-builder-plugin.
The bitbucket server has build-status API. It stores a build-status for particular commit, there is no separate PR build status. The PR build status is a build status of the head commit in this PR.
You can implement yourself the rest api call to update the build status or to use one of the existing plugins. We use Post Webhooks for Bitbucket bitbucket plugin in conjunction with Bitbucket Branch Source jenkins plugin.
You could you use BitBucket REST API to achieve this ?
Here the how-to update commits with the build status :
Updating build status for commits
Commit status are then shown in Pull Request and on branches
you can setup Stash notifier plugin , it workds perfectly with BitBucket and notifies build status to branch and pull request

How to trigger jenkins build upon bitbucket pull request merged
(2 answers)
Closed 5 years ago.
I have a Jenkins job which I want to trigger when I evaluate a pull request on Bitbucket. The Jenkins job is correctly configured (by the looks of it) with the 'Poll SCM' option checked.
I have setup the 'Bitbucket Server Webhook to Jenkins' as follows. When I click on 'Trigger Jenkins' as part of the configuration check, it works well. Corresponding logs on the Jenkins server show up properly.
Now, when I receive a pull request, I would want to trigger the same Jenkins job. However, which I click on the 'Trigger Build' option, nothing happens. The Jenkins job is not triggered. I dont see correspnding logs on the Jenkins server. No logs on the bitbucket server as well.
Where am I going wrong?
I am using an 'Atlassian Bitbucket v4.7.1' evaluation installation and a Jenkins 1.651 installation.
Just tried bitbucket 4.13 with webhook to jenkins for bitbucket 3.0.1 plugin. Follow the instruction on the plugin site, you need to install the git plugin on the jenkins side, enable git checkout and make sure it works, and enable polling of scm. The jenkins version used is pulled from docker hub with tag jenkins/jenkins:lts.
If the above does not work for you, from my reading you can have a few options as of today Nov 12 of 2017:
Use the generic post webhooks plugin that supports pull request trigger. And from jenkins pick it up with the generic webhooks plugin, then maybe do a secondary trigger from jenkins.
Upgrade the bitbucket server and webhooks to jenkins plugin. The server 4.13 does not work well with later webhooks to jenkins plugin. A paid version of the plugin probably is your best choice.

Github Jenkins plugin with Github Enterprise

I have a Jenkins server with the following github plugins:
github-api
github
github-pull-request
I want to trigger a build after a merge (from a PR). This is because I have some build chains that I don't execute when building a PR so after a merge I need to create new deployment packages.
In the enterprise github there doesn't seem to be the same interface (as regular github) for webhooks I don't seem to be able define what events the github plugin (webhook) should listen for so I think its just the default 'push' event. Is this done somewhere else or is it a limitation of the enterprise version?
UPDATE
I have the github plugin working now but its builds for every push if I check the box. This disucssion https://groups.google.com/forum/#!topic/jenkinsci-users/gew5gWVDxw8 suggests that I should be able to use the git scm and github plugin together. Github plugin will register a change, scm plugin will poll server to determine if this change was tho the watched branch. I also tried this suggestion How can I make Jenkins CI with git trigger on pushes to master?
When I try and configure this no branch is ever built!
At least for me it's not exactly clear from your question what you actually exactly want.
It sounds like you only want builds to be triggered if there are some new commits on github on a specific branch.
If this is all you're looking for, you can just setup a webhook (Jenkins (Github Plugin)).
In you Jenkins job, just specify the branch you're tracking (Branches to build).
Assuming you setup github's hoock to jenkins correctly, this should trigger your build job on each commit on github enterprise.
If your hook doesn't seem to work: To check if and what your github server actually would send to your jenkins server, you can temporarily replace the url to your jenkins server in github's webhook with something like requestb.in (this will let you inspect github's hook payload)
