CI/CD - 环境搭建(4) - 自动更新Next Release Version

前面已经实现最基本的当有Code Commit，会自动运行Jenkins Job，并把Artifact Upload到Artifactory上去。这中间的Version是手动来更改的，最好也跟着一并做成全自动化的。

Goal

Build成功后，自动更新Verion Number在Pom文件，并上传至Github。

Implementation

1. 通过Shell Script对Pipeline做了一些修改，增加获得Version，更改Version，上传Github

   node {
      def mvnHome
      
      stage('Checkout and Preparation') { // for display purposes
         // Get some code from a GitHub repository
         git credentialsId: 'ee7a726b-e672-424d-9b78-e8015668d55a', url: 'git@github.com:yongfeiuall/artifactory-maven-example.git'
         // Get the Maven tool.
         // ** NOTE: This 'M3' Maven tool must be configured
         // **       in the global configuration.           
         mvnHome = tool 'M3'
      }
      
      stage('Get current version') {
           sh "'${mvnHome}/bin/mvn' help:evaluate -Dexpression=project.version | grep -e '^[^\\[]' > version.out"
           version = readFile("version.out").trim()
           echo "Version is ${version}"
   		sh 'cat version.out |awk -F "-" \'{print $1}\' > release.out'
           release = readFile("release.out").trim()
   		echo "Release version is ${release}"
           
           sh 'cat release.out|awk \'{n=split($1,A,".");i=2;major=A[1];while(i<n) major = major "." A[i++];print major}\' > major.out'
           sh 'cat release.out|awk \'{n=split($1,A,".");print A[n]}\' > minor.out'
           major = readFile("major.out").trim()
           minor = readFile("minor.out").trim() as Integer
       }
   	
      stage('Build') {
         // Run the maven build
         sh "'${mvnHome}/bin/mvn' clean install -DskipTests"
      }
      
      stage('Results') {
         archive 'target/*.jar'
      }
       
       stage('Update pom with next development version') {
           sh "'${mvnHome}/bin/mvn' versions:set -DnewVersion=${major}.${minor+1}-SNAPSHOT -DoldVersion=* -DgroupId=* -DartifactId=* -DgenerateBackupPoms=false"
           sh script:'git status'
           modifiedFiles = sh(returnStdout: true, script: "git ls-files -m").trim()
           echo modifiedFiles
           if(modifiedFiles) {
               echo "commit required"
               fileAdded = sh(returnStdout: true, script: "git add .")
               sh(script: "git commit -m 'RELEASE_BUILD: changing to next development'")
               sh(script: "git push --set-upstream origin master")
             
               echo "commit completed"
           } else {
               echo "commit not required"
           }
       }
   }

2. 运行Jenkins Job
   

3. Github验证
