Jenkins to detect Pull Request from a forked branch in Bitbucket - jenkins

I have a bitbucket server that has a webhook configured with Jenkins.
Bitbucket has a master branch in it. I made changes in the local branch (let's call local_branch). When I git push --set-upstream origin local_branch this will create a forked branch in the bitbucket server.
My Jenkins cannot access the forked branch local_branch (which contains my changes) even though I added Jenkins as a user and give it read permission to my master branch. Unless I gave Jenkins read access to my forked branch, then my Jenkins can access the forked branch.
This is not intelligent if each one creates a forked branch and has to manually add Jenkins into the forked branch he/she created on the bitbucket server.
My goal is to let Jenkins trigger the job towards each person's forked branch whenever one creates a pull request from his/her forked branch on top of master branch.
Just wondering if anyone has ever encountered this.

Jenkins multibranch pipeline does not detect pull requests in Bitbucket server

I am having trouble getting Jenkins multibranch pipeline detect pull requests created in the Bitbucket server (private instance). I have setup the "Bitbucket server webhook to Jenkins" which is triggering the build on master, develop and feature branches except pull-requests. I have defined the build steps in Jenkisfile and can confirm the PR branch also includes the Jenkinsfile.
In the Jenkins configuration, I have enabled "Discover branches" under Branch Sources configuration
Pull Request isn’t a branch, it is usually something that is done prior to publishing to a branch. Usually, the pull request is approved, then published to the master branch.
Ok. After multiple trial and error and google search, I have managed to get the Jenkins Multibranch pipeline work with Bitbucket server. The key was to use 'Bitbucket' (from bitbucket branch source plugin) as the Branch source. Also, I had to include a dummy trigger in my Jenkinsfile for the Jenkins webhook to work from bitbucket
triggers {
bitbucketPush()
pollSCM('0 0 1 1 0')
}

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

Openshift - trigger Jenkins build on git push

I work with Openshift now and I have a problem.
I created an application server with Jenkins and when I push to the master branch of the git repository the Jenkins build is triggered automatically.
The point is that the build isn't triggered when I push to another branch (not master).
I've read topics like this one (How to configure Git post commit hook) and I do realize what the ways to make Jenkins build on git push are.
Unfortunately I haven't found any information about how this is done in the Openshift Jenkins. This mechanism is already implemented there and I simply want to replace the trigger from the "master" branch to another one.
How can I do it?
You can refer to the "Configuring Which Branch to Deploy" section from the following page:
https://developers.openshift.com/en/managing-deployments.html#configuring-which-branch-to-deploy

How to build the new branch pushed to github using Jenkins CI?

I've setup the Jenkins for the rails3 app to build the specs.
One can find many posts via google on how to setup the build trigger on the github push.
But what I want is to build the new remote branch pushed to Github.
e.g.
I've a repo origin/master. I cloned the repo, created a new branch, did some commits and pushed that branch to origin git push -u origin new_branch
Now I want the Jenkins to build this newly pushed branch on the origin.
If the build is successful, then Jenkins should merge it into origin/master automatically.
The Jenkins plugin has github, git plugin. But it requires to put the branch name. Instead I want to build the new_branch dynamically.
How can I setup such process?
If I remember correctly branch name is not a required entry. You need to test it, but I think if you do not fill it, Jenkins tests all new commit in the repo regardless which branch is affected.
But I recommend you do not merge automatically. You do not want that, trust me. :-)
It seems can not do that with only github and gitgub parameter plugin. If you specify branch_regex*** in Branch to build, Jenkins always build the latest commit in the bunch of branches that it saw. Must specify a branch in order Jenkins to build on the latest commit in that branch. I also see some answer with Multi Branch Pipeline but not sure how to deploy that way. There is no specific instruction at all.
