How to lock multiple stages of declarative Jenkins pipeline?

Question

I want to run multiple stages inside a lock within a declarative Jenkins pipeline:

pipeline {
    agent any
    stages {
        lock(resource: \'myResource\         


        

Answer 1

If the resource is only used by this pipeline you could also disable concurrent builds:

pipeline {
    agent any
    options {
        disableConcurrentBuilds()
    }
    stages {
        stage('will_already_be_locked') {
            steps {
                echo "I am locked before I enter the stage!"
            }
        }
        stage('will_also_be_locked') {
            steps {
                echo "I am still locked!"
            }
        }
   }
}
