Jenkinsfile 同时检出多个 Git 仓库

前置

通常,在 Jenkinsfile 中使用 Git 仓库是这样的:

stage('Checkout git repo') {     steps {         checkout([             $class: 'GitSCM',             branches: [[name: 'develop']],             userRemoteConfigs: [[                 credentialsId:  'ssh-private-key-id',                 url: 'project-git-repo-url'             ]]         ])     } } 

以上写法的结果是远程 Git 仓库中所有内容都被检出到当前工作目录下,因此我们才能像下面这样(不用切换目录而)直接运行一些命令:

stage('generate version number') {     steps {         VERSION_NUBMER = sh(script: "git describe --always", returnStdout: true).trim()     } } 

将 Git 仓库检出到指定文件夹

如果要同时拉取多个 Git 仓库,面临的首要问题是如何将 Git 仓库检出到指定文件夹。对此,可以通过使用 $class: 'RelativeTargetDirectory' 解决,具体代码如下:

stage('Checkout git repo') {     steps {         checkout([             $class: 'GitSCM',             branches: [[name: 'develop']],             userRemoteConfigs: [[                 credentialsId:  'ssh-private-key-id',                 url: 'project-git-repo-url'             ]],             extensions: [[                 $class: 'RelativeTargetDirectory',                 relativeTargetDir: 'repo-folder'             ]]         ])     } } 

这样一来,远程 Git 仓库中所有内容将被检出到 ./repo-folder 文件夹下;后续我们若想在 Git 项目目录下操作,就需要先 cd ./repo-folder 了,例如:

stage('generate version number') {     steps {         VERSION_NUBMER = sh(script: "cd ./repo-folder && git describe --always", returnStdout: true).trim()     } } 

检出多 Git 仓库

在解决了将 Git 仓库检出到指定文件夹这一问题后,检出多 Git 仓库这一需求就稍显容易,下面以检出repoA、repoB、repoC三个仓库为例:

stage('Checkout multiple git repos') {     steps {         checkout([             $class: 'GitSCM',             branches: [[name: 'develop']],             userRemoteConfigs: [[                 credentialsId:  'ssh-private-key-id',                 url: 'project-git-repoA-url'             ]],             extensions: [[                 $class: 'RelativeTargetDirectory',                 relativeTargetDir: 'repoA-folder'             ]]         ])          checkout([             $class: 'GitSCM',             branches: [[name: 'develop']],             userRemoteConfigs: [[                 credentialsId:  'ssh-private-key-id',                 url: 'project-git-repoB-url'             ]],             extensions: [[                 $class: 'RelativeTargetDirectory',                 relativeTargetDir: 'repoB-folder'             ]]         ])          checkout([             $class: 'GitSCM',             branches: [[name: 'develop']],             userRemoteConfigs: [[                 credentialsId:  'ssh-private-key-id',                 url: 'project-git-repoC-url'             ]],             extensions: [[                 $class: 'RelativeTargetDirectory',                 relativeTargetDir: 'repoC-folder'             ]]         ])     } } 

上面👆代码的结果就是工作目录下有了 repoA-folderrepoB-folderrepoC-folder 三个文件夹。

同时

截止现在,还没有达到我们的最终目的。本文标题叫做“Jenkinsfile 同时检出多个 Git 仓库”,但现在我们仅仅做到了“多个”还没有做到“同时”,为此我们需要使用Jenkins Pipeline语法中的 parallel 关键字。

stage('Checkout multiple git repos at the same time') {     parallel {         stage('repoA') {             steps {                 checkout([                     $class: 'GitSCM',                     branches: [[name: 'develop']],                     userRemoteConfigs: [[                         credentialsId:  'ssh-private-key-id',                         url: 'project-git-repoA-url'                     ]],                     extensions: [[                         $class: 'RelativeTargetDirectory',                         relativeTargetDir: 'repoA-folder'                     ]]                 ])             }         }          stage('repoB') {             steps {                 checkout([                     $class: 'GitSCM',                     branches: [[name: 'develop']],                     userRemoteConfigs: [[                         credentialsId:  'ssh-private-key-id',                         url: 'project-git-repoB-url'                     ]],                     extensions: [[                         $class: 'RelativeTargetDirectory',                         relativeTargetDir: 'repoB-folder'                     ]]                 ])             }         }          stage('repoC') {             steps {                 checkout([                     $class: 'GitSCM',                     branches: [[name: 'develop']],                     userRemoteConfigs: [[                         credentialsId:  'ssh-private-key-id',                         url: 'project-git-repoC-url'                     ]],                     extensions: [[                         $class: 'RelativeTargetDirectory',                         relativeTargetDir: 'repoC-folder'                     ]]                 ])             }         }     } }
