如何打印出Jenkinsfile中的class属性值？

pipeline {
    agent any
    stages {
        stage('Print Class') {
            steps {
                script {
                    def jenkinsfileClass = this.getClass().getSimpleName()
                    println "Jenkinsfile class: ${jenkinsfileClass}"
                }
            }
        }
    }
}

pipeline {
    agent any
    stages {
        stage('Print Class') {
            steps {
                script {
                    def jenkinsfileClass = this.getClass().getSimpleName()
                    echo "Jenkinsfile class: ${jenkinsfileClass}"
                }
            }
        }
    }
}
