groovy - How to create methods in Jenkins Declarative pipeline?

Question

In Jenkins scripted pipeline we are able to create methods and can call them.

Is it possible also in the Jenkins declarative pipeline? And how?

Answer 1

Newer versions of the declarative pipelines support this, while this was not possible before (~mid 2017). You can just declare functions as you'd expect it from a groovy script:

pipeline {
    agent any
    stages {
        stage('Test') {
            steps {
                whateverFunction()
            }
        }
    }
}

void whateverFunction() {
    sh 'ls /'
}
