我尝试了各种方式，但似乎没有任何效果。这是我的詹金文件。

def ZIP_NODE
def CODE_VERSION
pipeline{
    /*A declarative pipeline*/

    agent {
        /*Agent section*/ 
        // where would you like to run the code 
        label 'ubuntu' 
        }
    options{
        timestamps()
        }
    parameters {
        choice(choices: ['dev'], description: 'Name of the environment', name: 'ENV')
        choice(choices: ['us-east-1', 'us-west-1','us-west-2','us-east-2','ap-south-1'], description: 'What AWS region?', name: 'AWS_DEFAULT_REGION')
        string(defaultValue: "", description: '', name: 'APP_VERSION')

        }
    stages{
        /*stages section*/
        stage('Initialize the variables') {
            // Each stage is made up of steps
            steps{
                script{
                    CODE_VERSION='${BUILD_NUMBER}-${ENV}'
                    ZIP_NODE='abcdefgh-0.0.${CODE_VERSION}.zip'
                }
            }                
        }
        stage ('code - Checkout') {
            steps{
                checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxx', url: 'http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.git']]]) 
            }  
        }

        stage ('code - Build'){
            steps{
                sh ''' 
                    echo ${JOB_NAME}
                    pwd
                    echo ${ZIP_NODE}
                    echo 'remove alraedy existing zip files'
                    rm -rf *.zip
                    zip -r ${ZIP_NODE} . 
                    chmod 777 $ZIP_NODE 
                ''' 
            }
        }
        stage('Deploy on Beanstalk'){
            steps{
                build job: 'abcdefgh-PHASER' , parameters: [[$class: 'StringParameterValue', name: 'vpc', value: ENV], [$class: 'StringParameterValue', name: 'ZIP_NODE', value: ZIP_NODE], [$class: 'StringParameterValue', name: 'CODE_VERSION', value: CODE_VERSION], [$class: 'StringParameterValue', name: 'APP_VERSION', value: BUILD_NUMBER], [$class: 'StringParameterValue', name: 'AWS_DEFAULT_REGION', value: AWS_DEFAULT_REGION], [$class: 'StringParameterValue', name: 'ParentJobName', value: JOB_NAME]]
            }
        }
    }

}

阶段脚本的输出（“初始化变量”）没有任何作用，它没有设置全局变量ZIP_NODE的值：

[Pipeline] stage
[Pipeline] { (Initialize the variables)
[Pipeline] script
[Pipeline] {
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage

然后我们进入阶段（代码-Build），我们没有得到ZIP_NODE的值。请参阅22:34:17的echo声明

[Pipeline] stage
[Pipeline] { (code - Build)
[Pipeline] sh
22:34:16 [abcdefgh-ci-dev-pipeline] Running shell script
22:34:17 + echo abcdefgh-ci-dev-pipeline
22:34:17 abcdefgh-ci-dev-pipeline
22:34:17 + pwd
22:34:17 /home/advisor/Jenkins/workspace/abcdefgh-ci-dev-pipeline
22:34:17 + echo
22:34:17 
22:34:17 + echo remove alraedy existing zip files

感谢@awefsome，我有一些观察，我想补充一下细节：当我使用下面的代码时，我得到了想要的输出，即ZIP_NODE的正确值：

 stage ('code - Build'){
            steps{
                sh "echo ${JOB_NAME} && pwd && echo ${ZIP_NODE} && echo 'remove alraedy existing zip files' && rm -rf *.zip && zip -r ${ZIP_NODE} . && chmod 777 $ZIP_NODE"
            }
        }

但是，当我使用下面的代码时，我没有得到ZIP_NODE的值：

stage ('code - Build'){
            steps{

                sh ''' 
                        echo ${ZIP_NODE}
                        echo ${JOB_NAME}
                        pwd
                        echo ${ZIP_NODE}
                        echo ${CODE_VERSION}
                        #rm -rf .ebextensions
                        echo 'remove alraedy existing zip files'
                        rm -rf *.zip
                        zip -r ${ZIP_NODE} . 
                        chmod 777 $ZIP_NODE 
                    '''
            }
        }
