1 if控制語句

使用一個簡單的If控制語句

pipeline {
    agent any    
    stages {
        stage('flow control') {
            steps {
                script {
                    if ( 10 == 10) {
                        println "pass"
                    }else {
                        println "failed"
                    }
                }
            }
        }
    }
}

2 多個stage嵌套的語法

   pipeline {
    agent any    
    stages {
        stage('Non-Parallel Stage') {
            steps {
                echo 'This stage will be executed first.'
            }
        }
        stage('Parallel Stage') {
            failFast true
            parallel {
                stage('並行一') {
                    steps {
                        echo "並行一"
                    }
