Skip Default Checkout
Checkout Code
If you define a checkout stage in your Jenkinsfile, then Jenkins will first checks out the code on its own, and then it will follow the Jenkinsfile and pull the code for a second time.
pipeline {
agent any
stages {
stage('Checkout Code') {
steps {
git url: 'https://github.com/joseeden/test-project.git', branch: 'main'
sh "ls -lrt"
}
}
stage('Set Up Environment') {
steps {
sh "pip install -r requirements.txt"
}
}
}
}
This is because by default, Jenkins will pull the code for you. This means that it will connect to your code repository and checks it, before it proceeds to go through the instructions in the Jenkinsfile.
skipDefaultCheckout
If we don't want Jenkins to do a pre-checkout of the code, we can add the skipDefaultCheckout in the Jenkinsfile:
pipeline {
agent any
options {
skipDefaultCheckout()
}
stages {
stage('Checkout Code') {
steps {
git url: 'https://github.com/joseeden/test-project.git', branch: 'main'
sh "ls -lrt"
}
}
stage('Set Up Environment') {
steps {
sh "pip install -r requirements.txt"
}
}
}
}
This way it will proceed with the instructions on the Jenkinsfile without performing a pre-checkout of the code. You can also customize what Jenkins can pull from the code repository.
Remove any Checkout Stage
A more recommended way is to remove any checkout stage in the Jenkinsfile and let Jenkins perform the pre-checkout.
pipeline {
agent any
stages {
stage('Set Up Environment') {
steps {
sh "pip install -r requirements.txt"
}
}
}
}
