if-statement - Jenkins 声明式管道。post块中的条件语句

Question

有一个 Jenkins 管道。构建成功时需要/想要发送电子邮件。将有关所有分支的电子邮件发送到maillist-1并将 master 分支的构建过滤到maillist-master。
我尝试使用if和when语句步骤，但它们都在 post 块中失败。

pipeline {
  agent ...
  stages {...}
  post{
    success{
      archiveArtifacts: ...
      if( env.BRANCH_NAME == 'master' ){
        emailext( to: 'maillist-master@domain.com'
                , replyTo: 'maillist-master@domain.com'
                , subject: 'Jenkins. Build succeeded :^) '
                , body: params.EmailBody
                , attachmentsPattern: '**/App*.tar.gz'
        )
      }
      emailext( to: 'maillist-1@domain.com'
                , replyTo: 'maillist-1@domain.com'
                , subject: 'Jenkins. Build succeeded :^) '
                , body: params.EmailBody
                , attachmentsPattern: '**/App*.tar.gz'
        )
      }
    }

}

如何实现想要的行为？

Answer 1

确实，您目前不能when在全局帖子块中使用。When必须在阶段指令中使用。

使用 是一个合乎逻辑的选择if else，但您需要在声明性管道中使用脚本块来完成这项工作：

pipeline {
    agent any

    parameters {
        string(defaultValue: "master", description: 'Which branch?', name: 'BRANCH_NAME')
    }

    stages {
        stage('test'){
            steps {
                echo "my branch is " + params.BRANCH_NAME
            }
        }
    }

    post {
        success{
            script {
                if( params.BRANCH_NAME == 'master' ){
                    echo "mail list master"
                }
                else {
                    echo "mail list others"
                }
            }
        }
    }
}

参数为主时输出：

[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] echo
my branch is master
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
mail list master
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

参数为'test'时的输出：

[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] echo
my branch is test
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] script
[Pipeline] {
[Pipeline] echo
mail list others
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: SUCCESS

或者为了让它更干净，您可以将脚本作为函数调用：

pipeline {
    agent any

    parameters {
        string(defaultValue: "master", description: 'Which branch?', name: 'BRANCH_NAME')
    }

    stages {
        stage('test'){
            steps {
                echo "my branch is " + params.BRANCH_NAME
            }
        }
    }

    post {
        success{
            getMailList(params.BRANCH_NAME)
        }
    }
}

def getMailList(String branch){
    if( branch == 'master' ){
        echo "mail list master"
    }
    else {
        echo "mail list others"
    }
}
