Is there any way to make Jenkins builds after each commit in any branch ?
Because i found in my project's configuration that Jenkins run build only after detecting commits in specific branch or in the default ( eq to master in git ).
PS: i'm using mercurial and Jenkins file.
Should i change project type ( new item type in Jenkins ) or are there any modifications in configs.
There are two things that you should check for this (I haven't work with Mercurial)
Does Mercurial has the option to create webhooks?
There is a jenkins plugin for Mercurial? (I think there is)
You must configure on the mercurial site the webhook pointing to Jenkins and give the point to the job you want to run, and on which events does it will fire. On the Jenkins side you must configure on the job who it will behave.
For example, with GitLab, the plugin has an option configured on the "Build Trigger" section where you configure the events and the branches that fires the job. In GitLab, in the repository you create the webhook, that is only a URL pointing to the Jenkins job.
I got this solution and it worked for me.
with Mercurial, we can use the "tip" keyword.The tip revision is the most recent changeset in the repository. It is the most recently changed head.

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
Jenkins provides lengthy documentation regarding how to specify which branches it will build from. https://plugins.jenkins.io/git/
None of that though answers this specific question, or if it does, I cannot seem to achieve this.
How to specify that Jenkins will use whichever branch is normally checked out when cloning, such as the default branch specified in Github
Does this even make sense or is this even possible?
EDIT: specifically what should go in the red circle to checkout the default branch in Github
Jenkins respects the default branch over HEAD. Also, it depends how you configure you Jenkins job if it's a mulit-branch pipeline then you don't need to specify which branch it should build, by default it will scan you GitHub repo and build the changes made on branch and it will trigger the build.
If it's pipeline job then you can specify which branch it should built by editing the job configuration on Jenkins job and specifying the particular branch name in the section Branches to build
I hope this is what you are looking for.
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.
I am migrating my old Jenkins free-style job to multi-branch pipeline. I also want to use GitLab hook with them.
My problem is the branch detection. I am doing it manually but I want it to be automatic: when a new branch is pushed to git, GitLab trigger a Jenkins job that trigger the branch detection if the branch parameter from GitLab is not known for Jenkins at the moment. Is this possible to do it or doesn't this exist?
FYI: I tried to launch the multi-branch pipeline job but Jenkins says:
ERROR: No parameterized job named XXX found.
Enable "Build Periodcally" in your multibranch job configuration and the branch indexing will automatically started.
What you really need is a branch source plugin for GitLab with webhook integration, which is tracked as an RFE in JIRA.
Failing that, use a plain Git branch source and configure GitLab to send Jenkins notifications to /git/notifyCommit (IIRC) as documented on the Git plugin wiki. Need specify only a url, no other details. The branch indexing this triggers should both detect new or removed branches, and changes to the head of an existing branch, and schedule builds accordingly.
You can set webhook in GitLab for push events and URL like http://<yourserver>/git/notifyCommit?url=<URL of the Git repository>.
See https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin#GitPlugin-Pushnotificationfromrepository
GitLab notifies Jenkins on push events which should trigger branch detection also for multibranch pipeline.
I didn't receive the answer I wanted and I ran into this issue today that answered the question :
https://github.com/jenkinsci/gitlab-plugin/issues/298
TLDR: Multi-branch pipeline are not supported yet to be triggered by gitlab commit easily. There is a workaround. Look at the link above.
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)
