Trigger workflow on Github push - Pipeline plugin

Question

We are using the pipeline plugin with multibranch configuration for our CD. We have checked in the Jenkinsfile which works off git.

git url: "$url",credentialsId:'$credentials'

The job works fine, but does not auto trigger when a change is pushed to github. I have set up the GIT web hooks correctly.

Interestingly, when I go into a branch of the multibranch job and I click "View Configuration", I see that the "Build when a change is pushed to Github" is unchecked. There is no way to check it since I can not modify the configuration of the job (since it takes from parent) and the same option is not there in parent.

Any ideas how to fix this?

Answer 1

Before I start, I would like to emphasize that I had no previous experience with Jenkins so far, so there might be a bunch of better solutions out there.

What I wanted to achieve in a nutshell:

• After every push made to a Bitbucket repo(test2), on every branch,
  pull and build another Bitbucket repo(test1), from an identical
  branch name and right after that, build test2 using test1 as a
  dependency.

How I managed to achieve that?

• I started a new job with type 'Multibranch Pipeline'
• I added the following Jenkinsfile to test2:

pipeline {
    agent any
    stages {
        stage('build') {
            steps {
                dir('test1') {
                    git branch: BRANCH_NAME, url: '[e-mail]:user/test1.git', credentialsId: 'credentials_id'
                }
                sh('build_process')
            }
        }
    }
}

• I come across the issue that you can't set up a Bitbucket hook for pipelines

• I added Bitbucket Branch Source Plugin to Jenkins

• I selected Bitbucket at 'Branch Sources' when setting up the job

• I added credentials and put a checkmark to Auto-register webhook

• Under 'Scan Multibranch Pipeline Triggers' I put a checkmark to Periodically if not otherwise run, with an interval of 1 min

• I added a webhook to my Bitbucket repo

• I updated all my plugins, restarted Jenkins and it's ready to go

Other plugins I have installed: Bitbucket Plugin, Pipeline plugin. Hope this helps for somebody, I did manage to solve it this way after hours of struggling without the Bitbucket Branch Source Plugin.
