I have recently started using Jenkins Pipelines and have a multibranch job configured which is happily picking up Jenkinsfile on one of my branches.
I have seen in screenshots on posts\articles that Jenkins can report back to pull requests in GitHub the status of whether the branch has passed\failed checks performed in the pipeline.
I am not seeing any such feedback for my pull request I have opened, I can see in Jenkins it has triggered a pipeline build which has passed.
How can I get the notification to show the pipeline checks have passed in GitHub. Do I need to configure something else?
I found out this was simply down to me using the Git instead of GitHub sources option when configuring the multibranch pipeline job in Jenkins.
The docs for the GitHub Branch Source plugin gave me the clues!
I now get status messages on my pull requests showing whether pipeline checks are pending\failed\passed.
Check out the Github Pull Request Builder Plugin, it should do what you require: https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin

I currently have a fully functioning pipeline that's been deployed to a concourse server. It will receive push events from a github repo, and run the pipeline as such.
I have a webhook that's also able to talk from github to the concourseCI server.
It looks something like this:
https://concourse.myorganization.app/api/v1/teams/my_team/pipelines/git-repo-name/resources/git-repo-pull-requests/check/webhook?webhook_token=some_token
I have it dropped into the settings of the Github repo as a webhook, and it's returning 2xx after each push to a pull request. How can I get the status of the build in ConcourseCI to show up on the pull request like this
GitHub build status is independent from the webhook: the webhook goes from GitHub to Concourse, while here we need the opposite direction: from Concourse to GitHub. Also, it cannot be synchronous, since the webhook triggers a build that takes time to complete.
You need to signal the build status with a Concourse resource. The one I prefer (since I wrote it :-) is https://github.com/Pix4D/cogito.
I am using Jenkins Multibranch pipeline.
I've configured the APIs (github-webhook and ghprbhook) on GitHub.
Currently, If I click on "Scan Repository Now/Scan Repository Log" in Jenkins, the Jenkins will go through the GitHub and creates a new PR job in Jenkins if there are any PR on GitHub.
So I need to trigger this Multibranch pipeline whenever there is a Pull Request raised on GitHub. I want this pipeline to trigger automatically when there is a PR on GitHub.
What do I need to do to achieve this approach?
Is it possible to trigger Multibranch pipeline automatically whenever a PR is raised on GitHub?
To achieve this, I have selected only "Push and Pull Request" under "Let me select individual events" section of GitHub Webhooks.
PS: The GitHub branches are automatically detected in Jenkins.
Du you use the GitHub pull request builder plugin?
This Jenkins plugin builds pull requests from GitHub and will report the results directly to the pull request via the GitHub Commit Status API
When a new pull request is opened in the project and the author of the pull request isn't whitelisted, builder will ask Can one of the admins verify this patch?. One of the admins can comment ok to test to accept this pull request for testing, test this please for one time test run and add to whitelist to add the author to the whitelist.
If an author of a pull request is whitelisted, adding a new pull request or new commit to an existing pull request will start a new build.
A new build can also be started with a comment: retest this please.
I'm using Jenkins Multibranch pipeline. I've configured the APIs(github-webhook and ghprbhook) in GitHub. I want to trigger the Multibranch Pipeline whenever there is a Pull Request on GitHub (without using periodical option).
For example, if i create pull request on GitHub, then the Jenkins Multibranch pipeline should start scanning and build the Jenkinsfile automatically.
What do i need to do to achieve this?
I would love to try if there are any suggestions.
Under the webhook section, you can choose Let me select individual events option. Under that you can have push selected by default and also can select Pull Request which helps you to do wnat you are looking for Pull request opened, closed, reopened, edited, assigned, unassigned, review requested, review request removed, labeled, unlabeled, or synchronized.
To achieve this, I have selected "Send me everything" under GitHub Webhooks section.
Then I was able to trigger builds automatically whenever a PR is raised on GitHub.
As #RSharma mentioned, I have selected only "Push and Pull Request" under "Let me select individual events" section.
PS: The GitHub branches are automatically detected in Jenkins.
Using an organization type project in jenkins, I expected the pull requests to get automatically built.
I have a github webhook created in github settings. but nothing seems to be done?
Is there anything i need to put in my jenkinsfile to make this happen
It looks like the GitHubPullRequestBuilder is not compatible with Jenkins v2.0 pipeline jobs.
How do you configure a pipeline job to be triggered from a GitHub pull request event?
The documentation on this topic is sparse and I cannot find any examples of this. Or is it better to create a web-hook in GitHub to trigger the pipeline job on the PR event?
I had similar issue. Here’s what worked for me
Pre-req
Jenkins ver. 2+ (I was using Jenkins 2.60)
Github (or Githhub
enterprise) account
Your github and Jenkins must be able to talk to
each other.
On Github
create a github Personal Access Token (PAT) with relevant rights.
For your repo, create a webhook with
URL as YourJenkinsURL/github-webhook/
Choose ‘Let me select individual events’ and check ‘Pull Request’
Add a Jenkinsfile to the root folder of your repo. For testing purpose you could put content as a basic hello world like below
pipeline {
agent any
stages {
stage('Test') {
steps {
echo 'Hello World ...'
}
}
}
}
On Jenkins
Install GitHub Pull Request Builder plugin. (You also need “Github” plugin but that should normally be installed as part of Jenkins ver 2+)
Jenkins – Credentials
Add github Personal Access Token (PAT) as a ‘secret text’ credential.
Add github username-password as ‘username-password’ credential.
Manage Jenkins – Configure System
Github – Github Servers : This is part of the Github plugin. Add a github server. ‘API URL’ It will default to https://api.github.com. If you are using enterprise github, replace with enterprise github url followed by /api/v3. For credential select the PAT option. Test the connection. ‘Manage Hooks’ is checked.
GitHub Pull Request Builder : for ‘GitHub Server API URL’ use same url as specified in Github Server section. Leave ‘Shared Secret’ blank. For credentials use ‘username-password’ credential. Test credentials to ensure its working. In my settings, ‘Auto-manage webhooks’ was checked.
Pipeline Job
Create a new item using ‘Pipeline’ option. Note: This is the vanilla Pipeline job, not Multibranch Pipeline.
General Section: Check ‘Github Project’ – Project URL : Enter your github repo url
Build Triggers: Check ‘GitHub Pull Request Builder’
For ‘GitHub API credentials’ select option you set for GitHub pull request builder in ‘Manage Jenkins – Configure System’ screen
For admin list: add your username
Check Use github hooks for build triggering
Pipeline:
Select ‘Pipeline Script from SCM’. Note this assumes that the root folder of your repo will contain a ‘Jenkinsfile’
SCM: Select ‘Git’
Repositories – enter repo detail. For credentials use ‘username-password’ based credentials.
Click Advanced and add refspec as +refs/pull/*:refs/remotes/origin/pr/*
Branch – should be ${sha1}
Script Path: defaulted to Jenkinsfile, leave as is.
Lightweight Checkout - Uncheck this (https://github.com/jenkinsci/ghprb-plugin/issues/507)
That’s it. You are all set. Creating a PR on master branch of your repo should now trigger your Jenkins Pipeline job
Some observations
Redelivering the webhook payload of a PR from github does not trigger the pipeline but opening a new PR or even re-opening a closed PR on github, triggers the pipeline job
In Pipeline Job Configuration, if you choose “Pipeline Script” and paste your pipeline script in there, the job doesn't trigger !!!
The flow in a nutshell can go like this:
You create your pipeline as code and save it in a file called Jenkinsfile at the root dir of your project. That code should describe how your project will get built. See here for examples: https://jenkins.io/doc/pipeline/examples/
Then you should create a new "Multibranch Pipeline Project" item in your Jenkins. You should set this up so as to scan your repo of step 1.
Now whenever you get a new PR branch opened on your step 1 repo, the branch will be checked-out and will get built according to the Jenkinsfile instructions included with it. You can set up more conditions on what gets built and when if you want to.
Notes:
"Multibranch Pipeline Project" example documentation: https://jenkins.io/doc/book/pipeline-as-code/ (scroll down to Multibranch Pipeline Projects)
Keep in mind that getting the plugin to build a PR after commending on the PR does not work. There is a discussion analyzing this here: https://github.com/jenkinsci/gitlab-plugin/issues/298 There are workarounds (also described in that discussion) but they are quite messy to set up.
The most straightforward way to use Pipeline with GitHub pull requests is to put the script into your repository under the name Jenkinsfile and then install the GitHub Branch Source plugin. Documentation
Follow the Below Steps for Triggering Jenkins Job Automatically on Pull request generated on GitHub
Create a web hook on GitHub i.e. http:///generic-
webhook-trigger/invoke
Content Type :application/json
Select Pull Request as event Now github Configuration Part is done.
Jenkins Job Configuration
Download Generic Webhook Trigger in Jenkins
Git Hub Configuration On Jenkins
Git Hub Configuration
7.Select Generic Webhook Trigger on jenkins
8.Generic Webhook Trigger Configuration on Jenkinsand follow step 9
9.After doing step 7 Jenkins job will get trigger on PullRequest
10.Step 8 required to get information from Pull request Payload
11.Branch configuration inside Generic Webhook Trigger to get Branch details from Pull Request
