Question

我正在尝试将变量值从一个阶段传递给jenkins的邮件正文。但是变量值不能反映出来。

如果我创建另一个阶段并调用变量，该代码将起作用。但不是在 notifyStatusChangeViaEmail方法块

下面是示例代码。

def variable
pipeline {
agent { label 'master' }
options {
   timestamps()
   timeout(time: 1, unit: 'HOURS' )
}
  stages{
      stage('Variable'){
  steps {
    script{
  variable = "Hi, Build is successful"
      }
   }
  }
 }
}

def notifyStatusChangeViaEmail(prevBuild) {
def subject
def body

if (currentBuild.previousBuild != null) {
    switch (prevBuild.result) {
        case 'FAILURE':
            emailext attachLog: true, body: "${variable}", recipientProviders: [[$class: 'CulpritsRecipientProvider']], subject: 'Build Status : Build is back to Normal', to: 'sumith.waghmare@gmail.com';
            break

        case 'UNSTABLE':
            emailext attachLog: true, body: "${variable}", recipientProviders: [[$class: 'CulpritsRecipientProvider']], subject: 'Build Status : Build is back to Normal', to: 'sumith.waghmare@gmail.com';
            break

        case 'SUCCESS':
            emailext attachLog: true, body: "${variable}", recipientProviders: [[$class: 'CulpritsRecipientProvider']], subject: 'Build Status', to: 'sumith.waghmare@gmail.com';
            break
    }
}
}

问题在于该变量未在函数范围内定义（this post解释了Groovy中函数范围的工作原理。）

要解决此问题，您会发现我要么将variable设为notifyStatusChangeViaEmail的参数，要么删除def variable语句，因为那样会使variable全局变量，因此该函数将能够访问它。

示例：

使变量为notifyStatusChangeViaEmail的参数：

pipeline {
agent { label 'master' }
options {
   timestamps()
   timeout(time: 1, unit: 'HOURS' )
}
  stages {
    stage('Send Email') {
      steps {
        script {
          def emailBody = "Hi, Build is successful"

          // I assume that prevBuild is defined somewhere already

          notifyStatusChangeViaEmail(prevBuild, emailBody)
        }
      }
    }
  }
}

def notifyStatusChangeViaEmail(prevBuild, emailBody) {
  if (currentBuild.previousBuild != null) {
    switch (prevBuild.result) {
        case 'FAILURE':
            emailext attachLog: true, 
                     body: emailBody, 
                     recipientProviders: [[$class: 'CulpritsRecipientProvider']], 
                     subject: 'Build Status : Build is back to Normal', 
                     to: 'sumith.waghmare@gmail.com';
            break

      //...
    }
  }
}

将variable用作全局变量：

// --> I deleted the "def variable" line <--


pipeline {
agent { label 'master' }
options {
   timestamps()
   timeout(time: 1, unit: 'HOURS' )
}
  stages {
    stage('Variable') {
      steps {
        script {
          // There is no "def" when you first assign a value to
          // `variable`, so it will become a global variable, 
          // which is a variable you can use anywhere in your file
          variable = "Hi, Build is successful"
        }
      }
    }
  }
}
def notifyStatusChangeViaEmail(prevBuild) {
if (currentBuild.previousBuild != null) {
    switch (prevBuild.result) {
        case 'FAILURE':
            emailext attachLog: true, body: variable, recipientProviders: [[$class: 'CulpritsRecipientProvider']], subject: 'Build Status : Build is back to Normal', to: 'sumith.waghmare@gmail.com';
            break

     //...
    }
  }
}

使用变量作为参数：
