I need to run jenkin plan branch from bitbucket merge event.I have configure the jenkin plan branch source behaviours to discover merging pull request and identified when the time i have save that configs the plan get activated. Then the second code merge happen plan will not invoke.
Jenkin can not identify branch indexing for Multibranch pipeline plans.Can some one help me with this issue.I do not need to config webhooks from bitbucket server.

In GitLab, whenever someone creates a Merge Request from some branch into master, I need that event to trigger a Jenkins job (Freestyle, yeah I know..) and pass the branch name as a parameter for the Jenkins build.
I've looked and it seems like the closest thing to it is the Jenkins CI integration in GitLab. Thing is, These are the options to configure in the Jenkins CI integration, and it doesn't seem like it allows to trigger it only when the Merge Request is for master or to pass any parameters.
Is it possible to configure it so that only if a Merge Request to master occurs it would trigger the Jenkins job with the source branch as a parameter? Is there another/better way of doing it?
Thanks ahead!

I have implemented webhook in Bitbucket with only Merge Option Enabled, But whenever i do merge , it is triggering all the multibranch pipelines having new commits.
Below is the URL for Webhook in Bitbucket
https://Jenkins-URL/multibranch-webhook-trigger/invoke?token=TokenName
Webhook is scanned using Basic Build strategies plugin in multibranch pipeline in Jenkins
May i know how to stop other pipelines from triggering whenever merge is done.
I have a Jenkins multibranch pipeline for github and currently it triggers builds whenever a branch is indexed. I have certain actions in my pipeline that I only want triggered whenever there are changes to a branch (on a webhook push). So I was wondering if there's a Jenkins environment variable that will allow me to distinguish between the two different type of builds. Or if there's a git solution to check when the last change was made to the branch and differentiate it that way
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')
}
I am currently using Cloudbees Jenkins Coreas my Jenkins solution.
I am using Jenkins Pipelines to write our Jenkins job configuration. These pipelines are stored in GitHub repositories. Each Jenkins job when created is connected to a GitHub Repository where the source code is pulled from, and that's where the Jenkinsfile is stored and Jenkins reads from.
Below are some high-level photos for how our Jenkins jobs are configured.
The advantage of the way these jobs are configured is the Jenkinsfile is always read from the master branch. Meaning if a rouge developer tries to remove stages from the Jenkinsfile from within there own branch, it doesn't matter because the Jenkinsfile is always read from the master branch (which is always protected).
However, the one massive drawback to this - is how do teams and developers who are devops engineerings make changes to the Jenkinsfile? For example, let's say a developer creates a branch called feature-jenkins-search and they edit the Jenkinsfile adding a new stage in the pipeline. Whenever they push these changes to GitHub to test - they can't test as it's always read from the master branch? Meaning devops engineerings have to work directly on the master branch? Surely this is not the best way to go and there is a better configuration to set?
We do want to still provide the security that if a developer is rougue and
You should really look into the Jenkins multi-branch pipeline feature. The Jenkins multi-branch pipeline allows to create a single configuration item in Jenkins (a bit like a folder) that can detect all the branches and pull requests in a GitHub repository with a Jenkinsfile and build them using automatically created jobs. Inside this multi-branch pipeline object when it is configured in Jenkins, you will find a number of jobs to build the various branches and pull-requests in the GitHub repository.
So your developers should maintain a Jenkinsfile in every branch they work on in GitHub to build that branch in your Jenkins server.
It is possible to make the Jenkinsfile do branch specific handling if required with conditional stages / when conditions in the Jenkinsfile pipelines in each branch.
You can lock down the master branch so that code and Jenkinsfile changes from other branches can only be merged with an approved PR (pull request). There is good integration between Jenkins and GitHub such that you can configure the master branch to only allow a PR to be merged if the PR is buildable in Jenkins. So if developers add new stages / processing to a Jenkinsfile on a branch being merged to master, it should be validated so that builds of your master branch are not broken.
There is a lot of configurability in the Jenkins multi-branch pipeline object for detection and handling of branches and it may be necessary to experiment to get it right for what you need with your team. If you cannot find this feature in Jenkins, it is probably because the correct Jenkins pipeline and GitHub related plugins are not installed.
You could also have a look at a similar Jenkins feature called the Jenkins GitHub Organization Folder which allows to detect and build all repos and branches at a GitHub Organization level. But when starting out, I would suggest to look into the multi-branch pipeline at the single repo level first.
These features are discussed in the Jenkins pipeline documentation. We use these features with our internal GitHub and Jenkins server and it works very well.
I think you will find the idea of using a single Jenkinsfile in the master branch to be used for building all branches is unworkable, as you have seen!
