I am relatively new to the CI/CD concept.
I am trying to clone a Github repository using declarative pipeline in Jenkins (without SCM).
If i do it without any credentials then I can see in the console output that Jenkins is already trying to clone that repo but it takes extremely long . I can already see that in the Jenkins workspace I have a folder with the name of my github repo but it only has a .git folder inside it and it takes forever but never pulls the repo. After searching on the internet I found out that the permissions of accessing the repository were missing.
Then i added the credentials of my Github repo in Jenkins. I have the following script.
pipeline {
agent any
stages {
stage('clone repo') {
steps {
withCredentials(usernamePassword(credentialsId :jenkins-user-github ,passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME' )){
// Get some code from a GitHub repository
bat("""
git config --global credential.username {GIT_USERNAME}
git config --global credential.helper "!echo password={GIT_PASSWORD}; echo"
git clone https://github.com/aakashsehgal/FMU.git
echo "pulled the code"
""")
}
}
}
}
}
But i get the following error:

Any idea what am i missing here ?
When utilising the username and password inside the stage, you have a syntax problem. Instead of only {GIT_USERNAME}, you ought to have used ${GIT_USERNAME}.
Having said that, you need to explicitly mention to which branch you need to check out. I assume you'd want to checkout to master branch by default. So use the below:
pipeline {
agent any
stages {
stage('Checkout') {
steps {
script {
// The below will clone your repo and will be checked out to master branch by default.
git credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git'
// Do a ls -lart to view all the files are cloned. It will be clonned. This is just for you to be sure about it.
sh "ls -lart ./*"
// List all branches in your repo.
sh "git branch -a"
// Checkout to a specific branch in your repo.
sh "git checkout branchname"
}
}
}
}
}
If you want to checkout to a specific branch by default then use the below in your pipeline stage. With the below part, you won't need to run git checkout command separately.
pipeline {
agent any
stages {
stage('Checkout') {
steps {
checkout([$class: 'GitSCM', branches: [[name: '*/branchname']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'jenkins-user-github', url: 'https://github.com/aakashsehgal/FMU.git']]])
sh "ls -lart ./*"
}
}
}
}
