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声明性管道为 post 指令提供了在阶段结束后执行代码 .在阶段运行之前，并且最重要的是在SCM结帐之前，是否有类似的事情要运行代码 ?

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，类似以下内容的东西:

For example something along the lines of:

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

这将在检出源代码之前清理构建的工作空间.

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

推荐答案

pre是一个很棒的功能，但尚不存在. skipDefaultCheckout和checkout scm(与默认结帐相同)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'
      }
    }
  }
}
