Configure Global Settings:
After installing the plugin, configure global settings in Jenkins. Go to "Manage Jenkins" -> "Configure System." Look for the section titled "GitLab," and fill in the GitLab connection details.
Connection Name: A name for your connection.
GitLab host URL: The URL of your GitLab instance (e.g., https://gitlab.example.com).
Credentials: Add the GitLab API token or use username/password for authentication.
Create a New Jenkins Job:
Now, create a new Jenkins job that will be triggered by changes in your GitLab repository.
Click on "New Item" on the Jenkins homepage.
Enter a name for your project and choose the type of project (e.g., "Freestyle project" or "Pipeline").
In the "Source Code Management" section, select "Git."
Enter your GitLab repository URL.
In the "Build Triggers" section, check the box for "Build when a change is pushed to GitLab."
Set Up Webhook in GitLab:
To enable Jenkins to be triggered by GitLab events, you need to set up a webhook in GitLab.
In your GitLab project, go to "Settings" -> "Webhooks."
Enter the Jenkins URL followed by /gitlab-webhook/ (e.g., http://your-jenkins-url/gitlab-webhook/) in the "URL" field.
Set the webhook to trigger on push events.
Test the Integration:
Make a small change in your GitLab repository and push it. Check Jenkins to see if the build is triggered automatically. You should see the build details and console output in Jenkins.
Additional Tips:
Ensure that the Jenkins server can communicate with the GitLab server. Check firewall settings if necessary.
If you encounter any issues, check Jenkins and GitLab logs for error messages.
Make sure the Jenkins user has the necessary permissions to access the GitLab repository.
This should help you set up the integration between Jenkins and GitLab successfully. Adjust the settings based on your project's specific requirements.
