舞台和后行动之间詹金斯管道中变量的范围

Question

我有遵循用于自动化测试运行的管道代码，其中IM面临一个问题，在该问题中，阶段部分中定义的变量并试图在post Action部分中使用该变量的值，但是问题出现在此处，而变量的值则为null。因此，我怀疑这与变量范围有关。有人可以指导我解决这个问题吗？

请找到我的代码片段

import java.text.SimpleDateFormat
env.JenkinsAgent = 'JenkinsNode'
env.StartTime
env.EndTime

pipeline 
    {
    agent {label """'${JenkinsAgent}'"""} 
    stages 
        { 
       stage ('Execute Test Run & Notify Users')
            {
            steps 
                {
                script 
                    {
                    env.StartTime = new Date ()
                    env.StartTime = (env.StartTime.getTime())
                    echo "Epoch Timestamp - Start time is: ${StartTime} "
                    bat label: '', returnStdout: true,script: "Run.bat"
                    echo "LoadTest Execution completed" 
                    env.EndTime = new Date ()
                    env.EndTime = (env.EndTime.getTime())
                    echo "Epoch Timestamp - End time is: ${EndTime} "
                    }
                }
            post // action to be taken based on the above steps success or failure
            {
            success
                {
                script 
                    { 
                    currentBuild.result = 'SUCCESS'
                    echo "Load Test executed Successfully"
                    mail bcc: ' ',
                    body: """Test completed. Start time is ${StartTime} and End time is ${EndTime}""", 
                    cc: """${EmailCC}""", 
                    from: 'Jenkins', 
                    mimeType: 'text/html', 
                    replyTo: '',
                    subject: """Jenkins Alert: Stage : Execute Load Test completed""", 
                    to: """${EmailTo}"""
                    }
                }
            failure
                {
                script 
                    {
                    currentBuild.result = 'FAILURE'
                    error('Aborting the build.')
                    }
                }   
            }    
        }
    } // stages  
} //pipeline

如果要在阶段之间使用变量，则需要将它们定义为全局变量。请参阅以下管道。

// Global variable
def globalVar = "Initial Value"

pipeline {
    agent any

    stages {
        stage('Build') {
            steps {
                script {
                    echo "Printing initial values : ${globalVar}"
                    // Reassigning a value
                    globalVar = "New value"
                }
            }

            post {
                success {
                    echo "${globalVar}"
                }
            }
        }
    }
}
