Stop Jenkins Build - jenkins

We have recently moved to GitHub. But we are facing issue as,
whenever any user is making any commit to the file it is automatically triggering build in Jenkins.
Now the issue is, If more that one developer is working on same project and they are making the commit. so for every commit, Jenkins build is being triggered.
How can we stop this automatic build in Jenkins whenever commit is made?

If you have enabled Github webhook, disabled it.
or
if you have Poll SCM Turn ON disabled it on the Jenkins Job

Branch disabled in multibranch pipeline and reopened with Scan event

We have one project configured as multibranch pipeline project with branch filtered master and development. After few hours the master branch is disabled with a strikethrough symbol across its name and build option not available .
When clicked on "Scan Multibranch Pipeline", it enabled the branch and pipeline logs show "Branch ReOpened".
Initially we assumed it would be because of Option "Exclude branches included in pull request" but enabling "All branches" too is disabling the master branch time and time again.
Pipeline Logs are not providing any clear indication of whats happening causing it to disable .Please help .
Old topic but I faced the same error today but the solution was different.
The error was in the configuration of branch discovery
Discover branches > Strategy. I was using Exclude branches that are also filed as PRs
And there was a PR targeting this branch. Change for All branches did the trick.
This looks like a bug to me. First I'll go to http://[jenkins]/log/all to see if there are any interesting logs there, then I would open an issue on https://issues.jenkins.io/secure/Dashboard.jspa
Also this issue might be happening after a recent upgrade of jenkins plugins or jenkins itself, I would downgrade everything to try to get my jenkins back to the way it was, then upgrade the plugins one by one or few by few to try to isolate what is causing the issue.
Finally, if you have jobdsl scripts, I would check these scripts to see if there is not a script that when executed is recreating the job and overrides the disabled status
Not sure if you're using Bitbucket Branch Source plugin for hook on Jenkins, but I had the same issue on 737.vdf9dc06105be version. Everytime I pushed a change to branch (not pull request) it got disabled (strikethrough). Scan multibranch pipeline was restoring it until next push notification on webhook was performed.
Upgrading the plugin to 751.vda_24678a_f781 version resolved the issues:)

Prevent infinity loop builds when job push to github and triggers the webhook

I have a Github project with a webhook to trigger the build on Jenkins.
It works pretty well. I used the option "Trigger builds remotely" from Jenkins.
In the final steps of the build, it updates some files to update the package version, and submit it back to github.
This triggers a new build, generating an infinity loop of builds.
How to prevent this extra build to be triggered?
I tried the option "Polling ignores commits from certain users" to prevent builds from the bot user. but it seems to work only with the Polling process, and not the remote trigger.

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!

Jenkins builds are being triggered without a trigger

I inherited a project set up to use Jenkins. I set the trigger to poll SCM every 5 minutes and disabled the pre-existing build remotely trigger. So now the only trigger set for Jenkins is to poll SCM every 5 minutes. However jenkins is building the project everytime the project repo is updated and NOT on polling. The polling log specifically says that it won't build (due to the author of the commit being in the excluded list) but the project builds anyway, unrelated to the polling. There are no other triggers set.
I didn't find any scripts anywhere that could explain this behaviour.

Run Jenkins build for whichever branch was checked into on Gitlab

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.
