How to push code back to git in a Jenkins Pipeline script? - jenkins

Question

How can I check out code from git like this
stage('Checkout code') {
checkout scm
}
and modify the repository in the subsequent phase? Things like a git tag or a version commit.

Answer 1

Best I could come up with.
stage('Stage Checkout') {
checkout([
$class : 'GitSCM',
branches : scm.branches,
doGenerateSubmoduleConfigurations: scm.doGenerateSubmoduleConfigurations,
extensions : [] + [
$class : 'LocalBranch'
],
userRemoteConfigs : scm.userRemoteConfigs,
])
}
//do git stuff
stage('Push Version Back to Git') {
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: 'jenkins', usernameVariable: 'GIT_AUTHOR_NAME', passwordVariable: 'GIT_PASSWORD']]) {
sh 'echo ${GIT_AUTHOR_NAME} pushing '
sh 'git config --global user.email "user#test.com"'
sh 'git config --global user.name "Jenkins"'
sh 'git config --global push.default simple'
sh('git push https://${GIT_AUTHOR_NAME}:${GIT_PASSWORD}#github.com/a/a.git')
}
}

Having it as follows made it working to me. And another thing to remember is, if your password or username contains any special characters, make sure that they have been saved in the credentials with the encoded characters. Other it's never gonna work.
This happened to me too and I wasted hours... Crazzzy...
pipeline {
// ..
stages {
stage('Clone') {
steps {
sh "git config --global user.email 'root#my-domain.com'"
sh "git config --global user.name 'My Name'"
sh 'git config --global push.default simple'
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: '123123ghghjg13123', usernameVariable: 'GIT_AUTHOR_NAME', passwordVariable: 'GIT_PASSWORD']]) {
sh('git clone https://${GIT_AUTHOR_NAME}:${GIT_PASSWORD}#my-repo.git')
}
}
}
stage('Build') {
steps {
// ...
}
}
stage('Publish') {
steps {
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: '123123ghghjg13123', usernameVariable: 'GIT_AUTHOR_NAME', passwordVariable: 'GIT_PASSWORD']]) {
sh('git push https://${GIT_AUTHOR_NAME}:${GIT_PASSWORD}#my-repo.git --tags -f --no-verify')
}
}
}
}
}
