jenkins - 如何在管道的后部分定义变量？

Question

我想在管道后部分的不同条件下使用一些通用值，因此我尝试了以下操作 -

1.

post {  
      script {
           def variable = "<some dynamic value here>"
      }
      failure{
           script{
                  "<use variable  here>"
           }
     }
     success{
          script{
                "<use variable  here>"
         }
    }
}

2

post {  
          def variable = "<some dynamic value here>"
          failure{
               script{
                      "<use variable  here>"
               }
         }
         success{
              script{
                    "<use variable  here>"
             }
        }
    }

但它导致编译错误。

你能建议我如何在 post 中声明一个变量吗？哪个部分可以跨条件使用？

Answer 1

您可以使用 always条件是 guaranteed to be executed before any other conditions喜欢 success或 failure .如果您想存储 String值，您可以使用 env变量来存储它(环境变量总是将给定的值转换为字符串)。或者，您可以在 pipeline 之外定义一个全局变量。然后使用 always 中的预期动态值对其进行初始化状况。考虑以下示例:

def someGlobalVar

pipeline {
    agent any

    stages {
        stage("Test") {
            steps {
                echo "Test"
            }
        }
    }

    post {
        always {
            script {
                env.FOO = "bar"
                someGlobalVar = 23
            }
        }

        success {
            echo "FOO is ${env.FOO}"
            echo "someGlobalVar = ${someGlobalVar}"
        }
    }
}

输出:

Running on Jenkins in /home/wololock/.jenkins/workspace/pipeline-post-sections

[Pipeline] { (Test)
