如何在Jenkins多分支管道作业中仅构建一个目录? [英] How to only build one directory in a Jenkins multi-branch pipeline job?

问题描述

我有一个叫做multibranch-test的github存储库，带有两个子目录Project1，Project2.

I have a github repo called multibranch-test with two sub-directories Project1, Project2.

PS C:\Repos\multibranch-test> tree . Folder PATH listing for volume Windows Volume serial number is 2085-6D3D C:\REPOS\MULTIBRANCH-TEST ├───Project1 └───Project2

PS C:\Repos\multibranch-test> tree . Folder PATH listing for volume Windows Volume serial number is 2085-6D3D C:\REPOS\MULTIBRANCH-TEST ├───Project1 └───Project2

每个子目录都有一个Jenkins文件和该项目的代码.

Each sub-directory has a Jenkinsfile and the code for that project.

在詹金斯，我有两个多分支管道工作-一个用于Project1，一个用于Project2.在Project1的配置中，如果在Project2的子目录中推送了提交，则我不希望通过推送通知或轮询来构建Project1.

In Jenkins I have two multibranch pipeline jobs - one for Project1 and one for Project2. In the configuration for Project1 I don't want a push notification or polling to build Project1 if a commit was pushed in sub-directory for Project2.

因此在Project1中，我配置了其他行为:

So in Project1 I have configured Additional Behaviours:

• 高级克隆行为:选中了浅克隆
• 稀疏签出路径设置为Project1#
• 轮询会忽略某些路径中的提交
  • 包含的区域: Project1/*
  • 排除的地区: *
  • Advanced clone behaviours: Shallow clone is checked
  • Sparse checkout path is set to Project1#
  • Polling ignores commits in certain paths
    • Included Regions: Project1/*
    • Excluded Regions: *

    发生的事情是，如果我将提交推送到子目录Project2中的主目录，则会同时构建 Project1和Project2作业.我只希望Project2构建.有人可以指出我做错了什么吗?

    What is happening is if I push a commit to master in sub-directory Project2, both Project1 and Project2 jobs get built. I only want Project2 to build. Can someone point out what I'm doing wrong?

    两个项目的Jenkinsfiles相似，如下所示:

    Jenkinsfiles for both Projects are similar and look like:

    #!groovy
    node  {
        stage ('checkout') {
            checkout scm
        }
    
        stage ('build') {
            dir ('Project1') {
                bat 'powershell -Command gci'
                bat 'powershell -Command gci env:'
                bat 'powershell -File .\\Project1.ps1'
            }
        }
    

    推荐答案

    这对我们来说是一个很大的麻烦，但是我们能够通过一些解决方法来解决它.

    This has been a big hassle for us, but we were able to solve it with some workarounds.

    我们有一个由GitHub提交钩子触发的Jenkins主工作.它找出自上次提交以来发生了什么变化，然后触发其他 service-specific Jenkins作业.

    We have a master Jenkins job that's triggered by a GitHub commit hook. It figures out what changed since the last commit, and then triggers other service-specific Jenkins jobs.

    我们还使用了一些其他约定(例如，服务，目录和Jenkins作业的命名约定)，但希望可以对某些人有所帮助.

    We have some other conventions we're using (like naming conventions for services, directories, and Jenkins jobs) that aren't specified here, but hopefully this will help someone out.

    以下是解决方案中每个组件的细分:

    Here's a breakdown of each component in the solution:

    1. monorepo中每个服务的Jenkins作业和相应的Jenkinsfiles.

    C:\REPOS\MULTIBRANCH-TEST\Project1\Jenkinsfile(此处为构建逻辑) C:\REPOS\MULTIBRANCH-TEST\Project2\Jenkinsfile(您的构建逻辑在这里)

    C:\REPOS\MULTIBRANCH-TEST\Project1\Jenkinsfile (your build logic here) C:\REPOS\MULTIBRANCH-TEST\Project2\Jenkinsfile (your build logic here)

    1. shell脚本，获取自上次提交以来更改的列表(改编自 C:\REPOS\MULTIBRANCH-TEST\change-sets.sh

           #!/usr/bin/env bash
       
           changeSets=(`git diff-tree --name-status HEAD`)
           for(( i=0; i<${#changeSets[@]}; i++))
           do
             if [ ${changeSets[$i]} == "M" ]
             then
               echo ${changeSets[$i+1]}
             fi
           done
       

       1. 基于GitHub提交钩子的Jenkins作业

       C:\REPOS\MULTIBRANCH-TEST\Jenkinsfile

           #!/usr/bin/env groovy
       
           pipeline {
               agent any
       
               stages {
       
                   stage('Define Services to Build') {
                       steps {
                           script {
       
                               def SERVICES_TO_BUILD = sh script:"./change-sets.sh", returnStdout: true
                               SERVICES_TO_BUILD.split("\n").each {
                                   echo "Triggering build for ${it}"
                                   try {
                                       build job: "${it}", propagate: false, wait: false
                                   } catch (ex) {
                                       echo "Failed to trigger build for ${it}: ${ex.message}"
                                   }
       
                               }
                           }
                       }
                   }
               }
           }
