Jenkins 流水线语法 02 片段生成器和声明式语法生成器

Pipeline 开发工具

片段生成器

有些pipeline代码不是自己去写的，是要工具帮我们生成的，只需要知道怎么生成就行了

Jenkins会安装很多插件，有些插件会为你提供一些方法，也就是代码化的方法让你去使用片段生成器（下面就是安装好的插件为我们提供的所有功能）

流水线代码片段生成器， 非常好用。在这里可以找到每个插件以及Jenkins内置的方法的使用方法。使用片段生成器可以根据个人需要生成方法，有些方法来源于插件，则需要先安装相关的插件才能使用哦。

使用checkout生成器-gitlab代码

checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: 'dc735f39-1cef-4a12-a499-6c873b82adcc', url: '{ agent any stages { stage('getCode') { steps { checkout([$class: 'GitSCM', branches: [[name: '*/master']], extensions: [], userRemoteConfigs: [[credentialsId: 'dc735f39-1cef-4a12-a499-6c873b82adcc', url: ' } } }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on build-01 in /data/cicd/jenkinsagent/workspace/pipeline-test[Pipeline] {[Pipeline] stage[Pipeline] { (getCode)[Pipeline] checkoutThe recommended git tool is: NONEusing credential dc735f39-1cef-4a12-a499-6c873b82adccCloning the remote Git repositoryAvoid second fetchChecking out Revision dc647d4ef52aadabf75db582393156decc4ca6a3 (refs/remotes/origin/master)Commit message: "Update version"First time build.

使用sh生成器生成shell脚本

pipeline { agent any stages { stage('getCode') { steps { sh 'pwd' } } }}Started by user adminRunning in Durability level: MAX_SURVIVABILITY[Pipeline] Start of Pipeline[Pipeline] nodeRunning on Jenkins in /var/jenkins_home/workspace/pipeline-test[Pipeline] {[Pipeline] stage[Pipeline] { (getCode)[Pipeline] sh+ pwd/var/jenkins_home/workspace/pipeline-test[Pipeline] }[Pipeline] // stage[Pipeline] }[Pipeline] // node[Pipeline] End of PipelineFinished: SUCCESS

pipeline { agent any stages { stage('getCode') { steps { script{ sh ''' date pwd echo "hh" ''' } } } }}

stages { stage('build') { steps { // One or more steps need to be included within the steps block. } }}
