Hi Rama Raju,
The following is what I got from the web.
Please check if this is what you are looking for.


Managing version control for a Yocto build system after integrating it
with Jenkins involves several steps to ensure smooth and automated
builds. Here’s a guide to help you get started:

1. Set Up Version Control System (VCS)

First, ensure your Yocto project is stored in a version control system
like Git, GitHub, or GitLab. This allows Jenkins to track changes and
trigger builds automatically.

2. Install Jenkins Plugins

Install the necessary plugins in Jenkins to integrate with your VCS.
For Git, you can install the Git Plugin. Navigate to Manage Jenkins >
Manage Plugins > Available, search for the Git Plugin, and install it.

3. Configure Jenkins to Use VCS

In Jenkins, go to Manage Jenkins > Configure System. Under the Git
section, set the path to the Git executable. This ensures Jenkins can
access Git commands1.

4. Create a Jenkins Job

Create a new Jenkins job for your Yocto project. Click on New Item,
select Freestyle project or Pipeline, and give your job a name.

5. Source Code Management (SCM) Configuration

In the job configuration, go to the Source Code Management section and
select Git. Enter your Git repository URL1.

6. Set Up Build Triggers

Under the Build Triggers section, you can set up triggers to
automatically start builds. Options include:

Poll SCM: Jenkins will periodically check for changes in the
repository and start a build if changes are detected.

Webhooks: Configure your Git repository to send a webhook to Jenkins
whenever changes are pushed, triggering a build immediately.

7. Add Build Steps

Add build steps to your Jenkins job to handle the Yocto build process.
You can use shell scripts or predefined build steps to execute the
Yocto build commands2.

8. Automate Testing

Configure Jenkins to run automated tests after each build. This
ensures that any issues are caught early, and the quality of the build
is maintained.

9. Monitor and Maintain

Regularly monitor the Jenkins builds and maintain the build scripts
and configurations to ensure everything runs smoothly.

Example Jenkinsfile for Yocto Build

Here’s an example of a Jenkinsfile for a Yocto build:

groovy

pipeline {
agent any
stages {
stage('Checkout') {
steps {
git url: 'https://github.com/your-repo/yocto-project.git'
}
}
stage('Build') {
steps {
sh './build.sh'
}
}
stage('Test') {
steps {
sh './test.sh'
}
}
}
post {
success {
echo 'Build and tests passed!'
}
failure {
echo 'Build or tests failed!'
}
}

Thanks and Regards,
Anoop
