Setup Jenkins GitHub Branch Source plugin

This page provides information on how to setup Jenkins GitHub Branch Source plugin with GitBucket to use the GitHub Organization template job.

tested with


  • Install Jenkins as http://jenkins:9090/
    • Install the NodeJS plugin
  • Install GitBucket as http://gitbucket:8080/

Create a repository on GitBucket and clone it

I will create a NodeJS project, to run simple build and tests

  • Create a group on GitBuket as eg http://gitbucket:8080/wey-yu/hello (my group is named "wey-yu")

  • Create a hello repository on GitBucket (in the wey-yu group) as http://gitbucket:8080/wey-yu/hello (and initialize this repository with a README file)

  • Now locally clone the repository (git clone http://gitbucket:8080/git/wey-yu/hello.git)

  • Create this repository structure:

    ├── index.js
    ├── Jenkinsfile
    ├── package.json
    ├── .gitignore
    └── tests
      └── test.js

Source code(s)


  "name": "hello",
  "description": "hello",
  "main": "index.js",
  "scripts": {
    "test": "./node_modules/.bin/mocha tests/**",
    "start": "node index.js"  
  "devDependencies": {
    "chai": "^4.1.1",
    "mocha": "^3.5.0"


'use strict';

const expect = require('chai').expect;

describe('# 42 is 42', () => {
  it('should equal 42', () => {




the Jenkinsfile tells to Jenkins what to do at each push of commit

node {
  stage('Checkout') {
      git url: env.GITBUCKET_URL + "/wey-yu/hello.git", branch: env.BRANCH_NAME
  stage('Build') {
      def nodeHome = tool name: 'nodejs', type: ''
      env.PATH = "${nodeHome}/bin:${env.PATH}"
      sh "npm install"
      sh "npm test"  

you can write what you want inside index.js

Push the repository to GitBucket

git add .
git commit -m "🚀 first version of hello"
git push origin master

Setup of the GitBucket repository

  • Create a user on GitBucket for Jenkins as indythebot (in fact whatever you want)
    • Add indythebot as a collaborator of repository wey-yu/hello
  • Add repository webhook http://jenkins:9090/github-webhook/ (⚠️ don't forget the / at the end of the url)
    • Choose application/json for Content type
    • Check Pull request
    • Check Push
    • ⚠️ Remark: currently the hook does not seem to trigger Jenkins on push or when pull request
  • Create personal access token for indythebot on http://gitbucket:8080/indythebot/_application

Setup of Jenkins

Configure system

  • Go to http://jenkins:9090/configure
  • At the Global properties section:
    • Check Environment variables
    • Add this variable: GITBUCKET_URL with this value: http://gitbucket:8080/git (⚠️ don't forget the /git at the end of the url), this variable is used by the Jenkins file
  • At the GitHub Enterprise Servers section: (add a record if the section is empty)
    • Type the API endpoint: http://gitbucket:8080/api/v3
    • Give a name to the endpoint: eg gitbucket
  • Save

Global Tool Configuration

  • Go to http://jenkins:9090/configureTools
  • At the NodeJS section, add a "NodeJS item":
    • Type the name, eg nodejs (⚠️ this value is very important, it's used in the Jenkinsfile)
    • Keep the default settings
      • Install automatically is checked
      • Install from choose the last version of NodeJS (or an other version if you need it)
  • Save

Create and setup a new Jenkins job

Initialize the job

  • Go to http://jenkins:9090/view/all/newJob
    • Type the name of the new job, use the name ou your wey-yu group (aka orgnization)
    • Select GitHub Organization
    • Click on the OK Button

Setup the job

  • At the Projects/GitHub Organization section:
    • Set the API endpoint with the gitbucket endpoint
    • Create a "Username with password" credential with indythebot as user and its password (so, the web token is probably useless) and then select this new credential
    • Type the name of the Owner: it's the name of the group (wey-yu)
    • Keep only the Discover branches behavior and select the all branches strategy
    • Check the Project Recognizers section: you should have a Pipeline Jenkinsfile record with Jenkinsfile value for the Script Path field
  • At the Scan Organization Triggers
    • ⚠️ Check the Periodically if not otherwise run checkbox, and set to 1 minute (because currently the web-hook seems not working correctly°
  • Save

Return to the hello repository

  • Go to the settings of the hello repository (http://gitbucket:8080/wey-yu/hello/settings/options)
  • Select the Branches tab
    • At the Protected branches section
      • Choose master branch
      • Check Protect this branch
      • Check Require status checks to pass before merging
        • Check continuous-integration/jenkins/branch
      • Check Include administrators
      • Click on Save changes

Test the settings

New Branch

  • create a new branch (wip-display-hello) from master in GitBucket
  • update the index.js file
  • commit the update
  • you will see a new branch in the Jenkins dashboard (http://jenkins:8080/job/wey-yu/job/hello/)

New Pull Request

  • create a pull request from the wip-display-hello branch
  • now, in the pull request Conversation tab, you can see that the pull request has been checked by Jenkins

Write a bad test

  • on the same branch (wip-display-hello) change the content of /tests/test.js to write a "bad" test:
    'use strict';
    const expect = require('chai').expect;
    describe('# 42 is 42', () => {
      it('should equal 42', () => {
  • commit your changes
  • return to the pull request
  • you can see that you cannot merge the pull request

That's all 😉

You can’t perform that action at this time.
