Setting up a CI/CD pipeline in Jenkins for the repository ( AI Genereated)

 Setting up a CI/CD pipeline in Jenkins for the repository https://github.com/rehan02/exercise_java01 involves the following steps:

---

1. Prerequisites

• Jenkins Installed: Make sure Jenkins is installed and accessible.
• Jenkins Plugins:
  • Install the following plugins:
    • Git Plugin
    • Pipeline Plugin
    • Any relevant plugins for build tools like Maven or Gradle.
• Repository Access:
  • Ensure you have the credentials (username/password or token) to access the repository.
• Build Tool:
  • Ensure the project uses a build tool like Maven or Gradle. For Java, this is common.
• Environment:
  • Install Java and the relevant build tool on the Jenkins server.

2. Create a New Jenkins Job

1. Login to Jenkins.
2. Click on New Item in Jenkins dashboard.
3. Provide a name for the project and select Pipeline as the type. Click OK.

---

3. Configure Pipeline Script

Jenkins uses a Jenkinsfile to define the pipeline. Add a Jenkinsfile to your repository root, or define it directly in Jenkins.

Example Jenkinsfile for a Java Project Using Maven:

pipeline {
    agent any
    tools {
        maven 'Maven'  // Replace with your Maven installation name in Jenkins
        jdk 'JDK11'   // Replace with your JDK installation name in Jenkins
    }
    stages {
        stage('Checkout') {
            steps {
                git branch: 'main', url: 'https://github.com/rehan02/exercise_java01'
            }
        }
        stage('Build') {
            steps {
                sh 'mvn clean install'
            }
        }
        stage('Test') {
            steps {
                sh 'mvn test'
            }
        }
        stage('Deploy') {
            steps {
                echo 'Deployment steps go here!'
                // Add deployment commands like SCP, Docker, or Kubernetes deployment scripts.
            }
        }
    }
    post {
        success {
            echo 'Build and deployment succeeded!'
        }
        failure {
            echo 'Build or deployment failed!'
        }
    }
}

---

4. Configure Git Credentials

• Go to Manage Jenkins > Credentials.
• Add credentials for GitHub:
  • Username/password.
  • Or, better, use a personal access token.

---

5. Test the Pipeline

1. In the pipeline job, ensure the script is pointing to the Jenkinsfile in the repository or paste the above Jenkinsfile in the pipeline script section.
2. Click Build Now to trigger the pipeline.
3. Monitor the stages in the Jenkins console log.

---

6. Optional Enhancements

• Notifications:
  • Add notifications for build results (e.g., email or Slack).
• Quality Checks:
  • Integrate tools like SonarQube for code quality checks.
• Dockerize:
  • Use Docker containers for builds to ensure consistent environments.
• Artifact Storage:
  • Use tools like Nexus or Artifactory for managing built artifacts.

This configuration builds, tests, and sets a placeholder for deployment. Modify the Deploy stage as per your deployment environment. Let me know if you need help customizing it further!
