Jenkinsfile里定义对象和函数，获取git提交人， 发送钉钉通知

自从开始使用Jenkinsfile作为Jenkins配置后就一发不可收，因为开发者自定义CI脚本实在太方便了。

比如，最近开发的以一个项目涉及多人，提交冲突挺多的，有的人自己没编译通过就提交了，导致后面的人被阻塞，所以我们需要告诉他： 提交失败了。

首先，Jenkinsfile应该怎么用呢， 参见： https://www.cnblogs.com/woshimrf/p/gitlab-with-jenkins.html

定义Jenkinsfile的时候想要钉钉通知，首先获取git提交人：

最外层：    class MyChange {     String author;     String msg;  }  @NonCPS  def getChanges()  {      def changeLogSets = currentBuild.changeSets      for (int i = 0; i < changeLogSets.size(); i++)      {          def entries = changeLogSets[0].items          for (int j = 0; j < entries.length; j++)          {              def entry = entries[0]              def change = new MyChange()              change.author = entry.author              change.msg = entry.msg              return change          }      }    }    然后在node节点里定义变量    ding_group_access_token = "c20d35654da77a99d8869e04xxxxxxxd1a81aasssa2"  ding_jenkinsUrl = "http://jenkins.ryan.com/view/我的view名称/"    最后在失败的时候通知：      stage('Compile And UnitTest') {      echo "2.Compile the code"      try {          sh "mvn clean install"      } catch (Exception ex) {          updateGitlabCommitStatus name: 'build', state: 'failed'          def change = getChanges()          dingTalk accessToken: "${ding_group_access_token}", imageUrl: '', jenkinsUrl: "${ding_jenkinsUrl}", message: "@所有人 构建失败@$change.author $change.msg" , notifyPeople: "$change.author"          throw ex;      } finally {        }        updateGitlabCommitStatus name: 'build', state: 'success'  }

最终Jenkinsfile可能是这个样子的

文件位置  my-project  - .deploy     - Jenkinsfile  - src

在jenkins里创建pipeline job, 并指定Jenkinsfile

Jenkinsfile

class MyChange {     String author;     String msg;  }  @NonCPS  def getChanges()  {      def changeLogSets = currentBuild.changeSets      for (int i = 0; i < changeLogSets.size(); i++)      {          def entries = changeLogSets[0].items          for (int j = 0; j < entries.length; j++)          {              def entry = entries[0]              def change = new MyChange()              change.author = entry.author              change.msg = entry.msg              return change          }      }    }    node {      properties([gitLabConnection('gitlab-bigdata')])        stage('Prepare') {          echo "1.Prepare Stage"          checkout scm          updateGitlabCommitStatus name: 'build', state: 'pending'          mvn_module = '多模块项目mvn子模块'          pom = readMavenPom file: "${mvn_module}/pom.xml"          k8s_label = "项目在k8s集群中的名称"          docker_host = "自己的docker私服"          ding_group_access_token = "c20d35654da77a99d8869e041xxxac7d6699xxxxxx"          ding_jenkinsUrl = "http://jenkins.ryan.com/view/job所在的view/"          //要部署的k8s集群, 默认是杭州(config-hangzhou), 可选上海(config-shanghai)          k8s_cluster_node = "config-hangzhou"          //部署环境          profile=""          if(env.BRANCH_NAME == 'dev') {              profile = "dev"              k8s_cluster_node = "config-dev"          }          if(env.BRANCH_NAME == 'test') {              profile = "test"              k8s_cluster_node = "config-shanghai"          }          if(env.BRANCH_NAME == 'master') {              profile = "prod"              k8s_cluster_node = "config-hangzhou"          }            img_name = "${pom.groupId}-${pom.artifactId}"          docker_img_name = "${docker_host}/${img_name}"          echo "group: ${pom.groupId}, artifactId: ${pom.artifactId}, version: ${pom.version}"          echo "docker-img-name: ${docker_img_name}"          script {              build_tag = sh(returnStdout: true, script: 'git rev-parse --short HEAD').trim()              build_tag = "${env.BRANCH_NAME}-${build_tag}"                currentBuild.displayName = BUILD_NUMBER + "_" +build_tag          }      }        stage('Compile And UnitTest') {          echo "2.Compile the code"          try {              sh "mvn clean install"          } catch (Exception ex) {              updateGitlabCommitStatus name: 'build', state: 'failed'              def change = getChanges()              dingTalk accessToken: "${ding_group_access_token}", imageUrl: '', jenkinsUrl: "${ding_jenkinsUrl}", message: "@所有人 构建失败@$change.author $change.msg" , notifyPeople: "$change.author"              throw ex;          } finally {            }            updateGitlabCommitStatus name: 'build', state: 'success'      }            if (env.BRANCH_NAME == 'dev' ||env.BRANCH_NAME == 'test' || env.BRANCH_NAME == 'master') {          stage('Build Docker Image') {              echo "4.Build Docker Image Stage"              sh "docker build -t ${docker_img_name}:${build_tag} " +                      " --build-arg JAR_FILE=target/${mvn_module}.jar " +                      " --build-arg profile=${profile} " +                      " -f ${mvn_module}/.deploy/Dockerfile ./${mvn_module}"          }            stage('Push Docker Image') {              echo "5.Push Docker Image Stage"              //sh "mvn deploy -Dmaven.test.skip=true"              sh "docker tag ${docker_img_name}:${build_tag} ${docker_img_name}:latest"              sh "docker tag ${docker_img_name}:${build_tag} ${docker_img_name}:${pom.version}"              withCredentials([usernamePassword(credentialsId: 'docker-register-sz-shuwei', passwordVariable: 'dockerPassword', usernameVariable: 'dockerUser')]) {                  sh "docker login -u ${dockerUser} -p ${dockerPassword} ${docker_host}"                  sh "docker push ${docker_img_name}:latest"                  sh "docker push ${docker_img_name}:${pom.version}"                  sh "docker push ${docker_img_name}:${build_tag}"              }          }              stage("Deploy to k8s - ${profile}") {              echo "6.
