jenkins - 如何使用 Jenkins Pipeline 插件实现 Post-Build 阶段？

Question

读完 Jenkins tutorial 后解释Pipeline插件，看来插件应该可以实现Post-Build步骤。然而，文档在具体说明方面相当有限。

例如我想知道如何实现:

• Run only if build succeeds
• Run only if build succeeds or is unstable
• Run regardless of build result

• 仅在构建成功时运行

  stage 'build'
  ... build
  ... tests
  stage 'post-build'
  ...
  

  (或将 -Dmaven.test.failure.ignore=false 添加到 MAVEN_OPTS)

• 仅在构建成功或不稳定时运行

  stage 'build'
  ... build
  try {
      ... tests
  } catch {
      ...
  }
  stage 'post-build'
  ...
  

  (或将 -Dmaven.test.failure.ignore=true 添加到 MAVEN_OPTS)

• 无论构建结果如何都运行 - 可以使用 try/catch/finally 来完成吗？

  try {
      stage 'build'
      ...
  } catch {
      ...
  } finally {
      stage 'post-build'
      ...
  }
  

(我注意到最终构建状态设置为成功，即使某些阶段(即“构建”)失败，因为它是基于最后一个阶段设置的。这是否意味着最终构建状态需要显式设置，即currentBuild.result = 'UNSTABLE'？)

最好的方法是在管道脚本中使用构建后操作。

Handling Failures
Declarative Pipeline supports robust failure handling by default via its post section which allows declaring a number of different "post conditions" such as: always, unstable, success, failure, and changed. The Pipeline Syntax section provides more detail on how to use the various post conditions.

Jenkinsfile(声明式管道)

pipeline {
    agent any
    stages {
        stage('Test') {
            steps {
                sh 'make check'
            }
        }
    }
    post {
        always {
            junit '**/target/*.xml'
        }
        failure {
            mail to: team@example.com, subject: 'The Pipeline failed :('
        }
    }
}
