Motivation

Concept of Pipeline plugins it requires save Jenkinsfile in root repository. Workflow Multibranch Plugin extend this idea to build all branches in repository. This is very easy for CI.

In company may be many modules in separate repositories (I have over 100). This is exactly modules. They may be build one Jenkinsfile. But save duplicate Jenkins file each repository makes very hard support.

This is plugin have Jenkinsfile in global Jenkins script store. And load is for all tasks.

The Jenkinsfile may load specified Jenkinsfile from SCM for build concrete module branch.

Basics

This plugin extend workflow-multibranch-plugin and differs only one option in configuration

How it works

Config files load in order:

Jenkinsfile from root in checkout
Jenkinsfile from global Jenkins script store
Jenkinsfile from UI - not realized

Configuration steps

Create job

Enter name and select job type:

Select build mode

In job options go to "Build Configuration" section and select "by default Jenkinsfile":

If your select option "by Jenkinsfile" task will also work as a Workflow Multibranch Plugin

Select other options

All other options fully equivalent with Workflow Multibranch Plugin

Create and save default Jenkinsfile

Write your default Jenkinsfile (Pipeline write tutorial) and go to "Managed files" in jenkins manage section:

Add new config file with Groovy type and Jenkinsfile name:

Write pipeline:

After change global scripts may require administrative approval

Usage sample

All modules builds default Jenkinsfile. This is libs and other dependencies. But have modules with specific build configurations (run hard tests, deploy to docker etc.) Default configurations sample:

#!groovy
node('builder-01||builder-02||builder-03') {
    try {
        stage('Checkout') {...}

        stage('Prepare') {...}

        def hasJenkinsfile = fileExists 'Jenkinsfile'
        if (hasJenkinsfile) {
            load 'Jenkinsfile' // Loading Jenkinsfile from checkout
        } else {
            stage('Build') {...}

            stage('Test') {...}
        }
        currentBuild.result = 'SUCCESS'
    } catch (error) {
        currentBuild.result = 'FAILURE'
        throw error
    } finally {
        stage('Clean') {...}
    }
}

Jenkinsfile in SCM example:

#!groovy
stage('Build') {...}

stage('Deploy and Tests') {...}
currentBuild.result = 'SUCCESS'
