In a Groovy class:

private final Script script;

public MyClass(Script script) {
    this.script = script;
}

public myMethod() {
    this.script.env.test = "prout"
    this.script.println(this.script.env.test)

    this.script.properties([
       this.script.parameters([
            this.script.string(defaultValue: "${MY_VALUE}", description: 'the value', name: "${the_name}", trim: true),
            this.script.password(defaultValue: "${MY_PASSWORD}", description: 'the password', name: "${the_password}", trim: true)
        ])
    ])
}

In the pipeline:

stage('My Stage') {
    steps {
        script {
            MyClass toto = MyClass(this);
           toto.myMethod();
        }
    }
}

Anecdote : Pour appeler un job local, le step s'appelle "build", mais pour appeler un job distant c'est triggerRemoteJob... C'est quand même pas très homogène...

Ce job appelle un autre job en passant des paramètres :

pipeline {

    stages {
...

        stage('TRIGGER OTHER JOB') {
            steps {
                script {
                    println " ========== TRIGGER NEXT JOB ========== "
                    build job: 'other-job/master', parameters: [[$class: 'StringParameterValue', name: 'PROUT', value: "TRUC" ]]
                }
            }
        }

    }

}

Ce job récupère des paramètres :

pipeline {

    parameters {
        string(name: 'PROUT', defaultValue: 'VALUE', description: 'Received from previous job')
    }

    stages {

        stage('HELLO WORLD') {
            steps {
                script {

                    println " ========== HELLO WORLD II WITH ${PROUT} ========== "
                }
            }
        }

    }

}

Apparemment, faire simple c'est compliqué.

Comme j'ai pas envie de le faire plusieurs fois, je le met ici, en flat :

println " release version is now ${version} "

println " ========== CLONE REPO ========== "

    String[] numbersInVersion = currentVersion.split("\\.")
    String minorVersion = numbersInVersion[2]
    int newMinorNumber = Integer.parseInt(minorVersion) + 1
