1. Create a New Jenkins Job (Freestyle Project)

1. Log into Jenkins: Open your browser and navigate to your Jenkins URL (e.g., http://localhost:8080).
2. Create a New Job:
   • Click "New Item" on the Jenkins dashboard.
   • Enter Item Name: e.g., HelloMaven-CI. Don’t change the project name (if a project with this name already exists then delete the existing project),
   • Select "Freestyle project" and click "OK".

2. Configure Source Code Management (SCM)

Scroll to the "Source Code Management" Section:

• Select "Git".
• Repository URL: Enter your repository URL: https://github.com/devops-ds/your-maven-project.git
• Credentials: If the repository is private, click "Add" and provide the necessary credentials. (Not needed for the given public repository).
• Branch Specifier: (e.g., */main or */master). Use */main if you are using above link.

3. Add Build Steps

1. Scroll Down to the "Build" Section.

2. Add the Maven Build Step: Click "Add build step" and select "Execute shell".

   Configure the Shell Command:

   To find the full path to your mvn executable on open terminal in Ubuntu and run:

   which mvn
   

   

   The output will give you the full path (e.g., /usr/bin/mvn or /opt/maven/bin/mvn). Use this path in the command below in Jenkins Build Action Shell.

   #/path/to/your/maven/bin/mvn clean package
   # Example:
   /usr/bin/mvn clean package
   

3. Add the Ansible Deployment Step: Click "Add build step" again and select "Execute shell" (or "Execute Windows batch command" on Windows).

   Configure the Shell Command: In the command box, add a command to trigger your Ansible playbook.

   Note: It is highly recommended to upload your hosts.ini and deploy.yml files to your GitHub repository alongside your project code. This simplifies referencing them in Jenkins and keeps your automation code version-controlled.

   If your files are in the root of your repository (follow this command if you are using given github link), the command would be:

   ansible-playbook -i hosts.ini deploy.yml
   

   If you are not storing them in GitHub, use the full paths:

   ansible-playbook -i /path/to/hosts.ini /path/to/deploy.yml
   

   Note:

   • Replace /path/to/hosts.ini with the full path to your Ansible inventory file if not in GitHub.
   • Replace /path/to/deploy.yml with the full path to your Ansible deployment playbook if not in GitHub.
   • This command will run after the successful Maven build step.
