Start a pipeline from another in Jenkins


Suppose you want to start automatically a Jenkins Pipeline from another.
Besides, suppose you want to pass some variables from the first to the second one.
How can you do it?

Example


You have Pipeline 1 and Pipeline 2, and want to start Pipeline 2 from Pipeline 1





Pipeline 1

def params=[]

pipeline {
    agent any

    stages {
        stage('Start pipeline2') {

            script {
                
                params.add(string(name: "field1", value: "value1")
                params.add(string(name: "field2", value: "value2")

                build(job: "path/to/pipeline2", parameters: params)
            }
}
    }


Pipeline 2

pipeline {
    agent any

    stages {
        stage('Read parameters') {

            script {
                
                for (p in params) {
                    print p.key
                    print p.value
            }
            }
}
    }
}
