jenkins - 如何在多个代理上对Jenkins管道使用发布步骤？

Question

当使用每个阶段在不同代理上运行的Jenkins管道时，在开头使用agent none是good practice：

pipeline {
  agent none
  stages {
    stage('Checkout') {
      agent { label 'master' }
      steps { script { currentBuild.result = 'SUCCESS' } }
    }
    stage('Build') {
      agent { label 'someagent' }
      steps { bat "exit 1" }
    }
  }
  post {
    always {
      step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: "test@test.com", sendToIndividuals: true])
    }
  }
}

但是，这样做会导致在应发送电子邮件时导致 Required context class hudson.FilePath is missing错误消息：

[Pipeline] { (Declarative: Post Actions)
[Pipeline] step
Required context class hudson.FilePath is missing
Perhaps you forgot to surround the code with a step that provides this, such as: node
[Pipeline] error
[Pipeline] }

当我从 agent none更改为 agent any时，它可以正常工作。

如何在不使用 post的情况下使 agent any步骤起作用？

将执行邮件发送的step包装在node步骤中：

post {
  always {
    node('awesome_node_label') {
      step([$class: 'Mailer', notifyEveryUnstableBuild: true, recipients: "test@test.com", sendToIndividuals: true])
    }
  }
}
