有没有办法在声明性 Jenkins 管道中运行预结帐步骤? [英] Is there a way to run a pre-checkout step in declarative Jenkins pipelines?

问题描述

Jenkins 声明式管道 提供 post 指令以在阶段完成后执行代码.是否有类似的事情来运行代码在阶段运行之前，最重要的是，在 SCM 结帐之前?

Jenkins declarative pipelines offer a post directive to execute code after the stages have finished. Is there a similar thing to run code before the stages are running, and most importantly, before the SCM checkout?

例如:

pre {
    always {
        rm -rf ./*
    }
}

这将在签出源代码之前清理我的构建工作区.

This would then clean the workspace of my build before the source code is checked out.

推荐答案

pre 是一个很酷的功能想法，但还不存在.skipDefaultCheckout 和 checkout scm(与默认 checkout 相同)是键:

pre is a cool feature idea, but doesn't exist yet. skipDefaultCheckout and checkout scm (which is the same as the default checkout) are the keys:

pipeline {
  agent { label 'docker' }
  options {
    skipDefaultCheckout true
  }
  stages {
    stage('clean_workspace_and_checkout_source') {
      steps {
        deleteDir()
        checkout scm
      }
    }
    stage('build') {
      steps {
        echo 'i build therefore i am'
      }
    }
  }
}
