[FIXED] How to load a Groovy script from a git repo in a Jenkinsfile that is in a different git repo

Issue

So I have a groovy script called "deployer.groovy" that is in a git repository called "jenkins-pipeline-library". (https://github.com/xyzDev/jenkins-pipeline-library) there is nothing else in this repository just this groovy file in the main branch.

Also, I have a Jenkinsfile that is in a different git repository. I cannot put both of these file in a same Git repository.

(because im not allowed to, the idea is to be able to run this deployer.groovy by using Jenkinsfile so that people dont see the content of the deployer.groovy but be able to use it)

I am trying to load this deployer.groovy in my Jenkinsfile and then run it.

Is there any way to do this? Please any suggestions would be highly appreciated.

Solution

Official documentation

Extending with Shared Libraries is the documentation that I would recommend for you to understand and achieve what you need.

Explanation

Jenkins configuration: Go to jenkins-url/configure -> Global Pipeline Libraries in this section you can setup the library: using libraries, retrieval method

Library repository: Shared library repository should have the .groovy files in specific folder structure, for your use case you need this:

(root)
+- vars
|   +- foo.groovy               # for global 'foo' variable
|   +- MyDeclarativePipeline.groovy  # for global 'MyDeclarativePipeline' variable

vars/foo.groovy

#!/usr/bin/env groovy

def test() {
  // define logic here
}
def deployInternal() {
  // define logic here
}

vars/MyDeclarativePipeline.groovy

#!/usr/bin/env groovy

def call() {
    /* insert your pipeline here */
    pipeline {
        agent any
        stages {
            stage('Test') {
                steps {
                    // input the logic here or
                    foo.test()
                }
            }
            stage('Deploy Internal') {
                steps {
                    // input the logic here or
                    foo.deployInternal()
                }
            }
        }
    }
}

Jenkinsfile:

@Library('my-shared-library') _

MyDeclarativePipeline()

Note: instead of MyDeclarativePipeline() you can insert the pipeline {...} block which was defined in MyDeclarativePipeline.groovy
