Automatically commit code by Jenkins

When we need to release a product, we should change copyright, build version, release month, release note…
How to modify multiple files automatically?
I used a Jenkins pipeline project, the project is parameterized(string parameter) and regular expressions to implement.

1. Here is the string parameter for copyright:

   • Name: copyright

   • Default Value: 1995—2019

   • Description: Copyright format:1995—2019

     stage('change copyrigh') {
         steps {
             sh label: '', script: 'sed -i -E "s/(1995—[0-9]{4})/${copyright}/" 1033/AutoRun.ini'
         }
     }

2. Here is the string parameter for build version:

   • Name: build_version

   • Default Value: 1.2.2.1002

   • Description: build version format: 1.2.2.1002

     stage('change build version') {
         steps {
             sh label: '', script: 'sed -i -E "s/([0-9].[0-9].[0-9].[0-9]{4})/${build_version}/" 1033/AutoRun.ini'
         }
     }

3. Here is the string parameter for build version:

   • Name: release_month

   • Default Value: May 2019

   • Description: release month format: May 2019

     stage('change release month') {
         steps {
             sh label: '', script: '''
             sed -i -E "s/([a-z]* 20[0-9]{2})/${release_month}/" 1033/AutoRun.ini
             sed -i -E "s/([a-z]* 20[0-9]{2})/${release_month}/" 1033/MainMenu.ini
             '''
         }
     }

4. push change to Git

   stage('git push to Git') {
       steps {
           sshagent(['8dd766ba-ac0f-4302-afa8-bee59c726dee']) {
               sh("git add 1033/AutoRun.ini")
               sh("git add 1033/MainMenu.ini")
               sh("git commit -m 'Bld # ${build_version}'")
               sh("git push -u origin master")
           }
       }
   }

5. Whole Jenkins Pipeline looks like:

   pipeline {
       agent {
           label 'master'
       }
   
       stages{
           stage('git clone') {
               steps{
                   git branch: 'master',
                   credentialsId: '8dd766ba-ac0f-4302-afa8-bee59c726dee',
                   url: 'git@github.com:shenxianpeng/blog.git'
               }
           }
   
           stage('change copyrigh') {
           steps {
               sh label: '', script: 'sed -i -E "s/(1995—[0-9]{4})/${copyright}/" 1033/AutoRun.ini'
           }
           }
   
           stage('change release month') {
           steps {
               sh label: '', script: '''
               sed -i -E "s/([a-z]* 20[0-9]{2})/${release_month}/" 1033/AutoRun.ini
               sed -i -E "s/([a-z]* 20[0-9]{2})/${release_month}/" 1033/MainMenu.ini
               '''
           }
           }
   
           stage('change build version') {
           steps {
               sh label: '', script: 'sed -i -E "s/([0-9].[0-9].[0-9].[0-9]{4})/${build_version}/" 1033/AutoRun.ini'
           }
           }
   
           stage('git push to Git') {
               steps {
                   sshagent(['8dd766ba-ac0f-4302-afa8-bee59c726dee']) {
                       sh("git add 1033/AutoRun.ini")
                       sh("git add 1033/MainMenu.ini")
                       sh("git commit -m 'Bld # ${build_version}'")
                       sh("git push -u origin master")
                   }
               }
           }
       }
   }
