Prerequisites:

Before you begin, ensure you have met the following requirements:

• Java Development Kit (JDK): Ensure you have JDK 8 or higher installed. You can download it from Oracle's website or use OpenJDK. ☕
• Maven: Apache Maven is used for building the project. Download and install Maven from Maven's official website. 📦
• Apache Tomcat: A web server and servlet container for deploying the WAR file. Download it from Apache Tomcat's website. 🖥️
• Git: Required for cloning the repository. Install Git from Git's official website. 🧩

Getting Started:

1. Clone the Repository:

   git clone https://github.com/your-username/JavaLoginShowcase.git

2. Navigate to the Project Directory:

   cd JavaLoginShowcase

Deployment Instructions:

1. Build the Project:

   • Use Maven to clean and package the application into a WAR file:

     mvn clean package

   • This command will generate a WAR file in the target directory (e.g., target/JavaLoginShowcase.war). 📦

2. Deploy to Tomcat:

   • Copy the WAR file to the Tomcat webapps directory:

     cp target/JavaLoginShowcase.war $TOMCAT_HOME/webapps/

   • Restart the Tomcat server to deploy the WAR file:

     $TOMCAT_HOME/bin/shutdown.sh
     $TOMCAT_HOME/bin/startup.sh

3. Access the Application:

   • Once deployed, access the application through your web browser at:

     http://localhost:8080/JavaLoginShowcase

Java Application CI/CD Pipeline to Tomcat (Azure DevOps)

---

🚀 Purpose of This Repository

This repository demonstrates a CI/CD pipeline for a Java (Maven) application, with a focus on:

• Build and quality analysis
• Artifact packaging
• Automated deployment to a Tomcat server running on a Virtual Machine

⚠️ The application itself is intentionally simple.
🎯 The primary focus is on CI/CD pipeline design and deployment automation.

---

🏗️ Technology Stack

• Application: Java (Maven, WAR packaging)
• CI/CD: Azure DevOps Pipelines
• Code Quality: SonarQube / SonarCloud
• Deployment Target: Tomcat on Linux VM (SSH-based deployment)

---

🔄 CI/CD Pipeline Overview

The pipeline follows a multi-stage structure:

1️⃣ Build & Quality Analysis

• Maven build (clean verify)
• SonarQube static code analysis
• Artifact packaging (WAR file)

2️⃣ Linting

• StyleLint for frontend/static assets (non-blocking)

3️⃣ Deployment

• Download build artifacts
• Install Tomcat (if not present)
• Deploy WAR file to Tomcat webapps directory
• Restart Tomcat service
• Verify application availability

---

🧩 Pipeline Highlights

✅ Multi-stage Azure DevOps pipeline
✅ Artifact-based deployment strategy
✅ VM deployment using SSH tasks
✅ Separation of build and deploy concerns
✅ Realistic VM-based delivery flow

This mirrors how many legacy and hybrid enterprise systems are still deployed today.

---

🔐 Security Notes

• Secrets and tokens should be stored in Azure DevOps secure variables or service connections
• No credentials should be hardcoded in pipeline definitions

---

🎯 Why This Project Exists

This repository complements my other work focused on:

• Enterprise CI/CD pipelines
• Infrastructure as Code
• Cloud platform engineering

It represents VM-based application delivery, which remains relevant in many real-world environments.
