I want to create a PR to my git repository from a jenkins pipeline.
I know it's a bit revers flow than the general flow where we trigger jenkins job based on PRs.
But in my case, user will manually trigger a job & I will create clone an existing git repo. After that, will update some files (via the same job pipeline). And then I want these changes to be pushed to my github repo & have a PR ready to be reviewed by the devs.
Is there any way to do this ?
I am trying around hub but want to know if there's any other way of achieving this?

We are using Bitbucket cloud to host our repos and Jenkins for CI/CD.
I have setup a multibranch pipeline which has develop and release branches. I want to trigger develop branch whenever a PR is merged from the feature branches to develop a branch (In fact on any manual webhook edit).
Below are the cases I tried:
Setup Manage hook in Jenkin:
This creates a webhook in bitbucket and when PR is merged, build is triggered.
But when I disable the Repository Push option in the webhook, the build is not triggering on PR merge.
Setup the webhook manually:
In this case, the Jenkins logs show the branch name as PR-XY since not triggering the develop branch.
I have set up a regex to filter branches (only develop and release are allowed) and when I add regex like PR(.*) then build gets triggers from the PR section (not desired case).
I want the build to be triggered from the develop branch, not as the PR branch. I have followed most of the options available in the forums but it's not working. Any help regarding this will be appreciated.
I faced the same issue, it's look like most of jenkins plugins like bitbucket plugin does not trigger the pipeline on merge only. even though i set the bitbucket trigger options like this:
unless you add a check mark next to push option.
to solve this i used another Jenkins plugin called Bitbucket Push and Pull Request
just make sure to uninstall Bitbucket plugin if you have it.
so you can use this one as they mentioned in there docs.
and follow the setup instructions.
note: i only test it with normal pipeline job
I'm using Bitbucket as a git management repository solution, and I want automatically create PRs, when my feature branches builds are successful.
So, is there any way to set this up with a Jenkinsfile?
I recently made the transition from Subversion to Git for all my repos at work. However, with svn we had commit hooks in place so that our Jenkins job would run for whichever branch was checked into. Now, I'm trying to set this up using Gitlab and there appears to only be one place to add a web hook. It looks like any time something is checked into ANY branch, the web hook will run. Meaning if I have a branch_A associated with jenkins_job_A, something could be checked into branch_B and the commit hook for jenkins_job_A will still run. Is there a branch by branch way to configure these web hooks? Or is there some kind of script I can check into each branch that will act as a commit hook? Or (my fear) is this feature not supported in Gitlab?
I guess you set up GitLab to do a post commit request to http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>? In theory this should trigger the polling on all jobs that are configured with that URL, and in the polling step the jobs should decide whether they should build or not. In practice this will unfortunately cause all jobs to fire.
We worked around this issue by moving the Job configuration into a Jenkinsfile and then use a Multibranch Pipeline.
As an alternative you could also install the GitLab plugin for Jenkins and use the Jenkins integration in GitLab. This will allow you to trigger the correct jobs when commits are pushed on a branch. The downside is that it requires a per-job configuration.
To give some context the question is about GitLab and Jenkins setup.
I know how to setup a web hook, I know how to setup a job to be triggered by the hook. The problem is that I need to have multiple jobs and only a single entry-point (parent job) trigger for them.
The downstream jobs at the same time need to be git repo aware so I have to set repo url for them. This causes them to be triggered independently by the hook and I don't want that as this means that they are triggered twice.
On the other hand if I don't configure repo url on a downstream job and the parent job triggers it, it fails as it is not able to do a checkout.
I may try to hack around with some 'execute shell' build step, I believe it's not a valid way to go. Has anybody a good tip how to solve that?
For the reference here is the GitLab Jenkins plugin documentation according to which:
Plugin will parse the GitLab payload and extract the branch for which
the commit is being pushed and changes made. It will then scan all Git
projects in Jenkins and start the build for those that:
match url of the GitLab repo
match the configured refspec pattern if any
and match committed GitLab branch
I tried playing around with different settings, without a great result though.
For the project you want to get only local triggers, just enable Don't trigger a built on commit notification in the Additional behaviours of git plugin.
(https://github.com/elvanja/jenkins-gitlab-hook-plugin/issues/11#issuecomment-35385032, as you actually have discovered).
But a better solution could be to make your downstream jobs reference the repository locally cloned by main job (not sure if actually possible), so the plugin will never consider them for schedule a build, as the git url don't match.
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)
