jenkins 管道 sh returnStatus 拋出異常

Question

我正在嘗試編寫一個 jenkins 聲明性管道代碼來執行一個 shell 腳本並捕獲代碼的退出狀態。 當我嘗試執行時，它會引發異常。

pipeline {
    stages {
        stage ('shcheck'){
            steps {
                echo 'Hello world - shcheck'
                status = sh(
                    returnStdout: true, 

                    script: '''#!/usr/bin/bash
                        echo 'testing sh'
                        exit 0
                    '''
                )

            }
        }

    }
}

執行此操作時，我得到以下執行：

我希望 0 存儲在 ' status ' 變量中。 我不確定我是否缺少任何插件或配置設置。

您的管道存在導致驗證失敗的語法錯誤。

1. 失蹤agent
   
2. status = sh ()需要放在script里面

固定代碼：

pipeline {
  agent any

  stages {

    stage ('shcheck'){
      steps {
        echo 'Hello world - shcheck'

        script {
          status = sh(
              returnStdout: true, 

              script: '''#!/usr/bin/bash
                  echo 'testing sh'
                  exit 0
              '''
          )
        }
      }
    }

  }
}
