Hello Java Maven – Jenkins CI/CD Build

This project demonstrates how to build a simple Java application using Maven in Jenkins.
It is designed as an introductory Continuous Integration (CI) example, running either locally or on a remote server (e.g., AWS EC2).

---

📌 Project Overview

This repository contains:

• A basic Java HelloWorld application
• A pom.xml file for Maven build configuration
• Instructions to set up a Jenkins Freestyle job to build the application

The Jenkins job:

1. Clones this repository from GitHub.
2. Builds the project using Maven (clean package).
3. Optionally archives the generated .jar file as a build artifact.

⚙️ Setup Instructions

1. Clone the Repository

git clone https://github.com/TechnicalGaur/hello-java-maven.git
cd hello-java-maven

🚀 Jenkins Setup Guide

Step 1 – Install Jenkins (Docker Example)

docker run -d --name jenkins \ -p 8080:8080 -p 50000:50000 \ -v jenkins_home:/var/jenkins_home \ jenkins/jenkins:lts

Step 2 – Configure Maven in Jenkins

Go to Manage Jenkins → Tools → Maven installations

Add Maven (e.g., Maven 3.x) and check Install automatically

Step 3 – Create a Freestyle Job

New Item → Freestyle project → Name: hello-java-maven

Source Code Management:

-Select Git

-Repository URL: https://github.com/TechnicalGaur/hello-java-maven.git

Branch Specifier: */main (or */master if using master branch)

Build → Invoke top-level Maven targets:

Maven Version: Maven 3.x

Goals: clean package

Post-build Actions (Optional):

Archive artifacts: target/*.jar

Step 4 – Build the Job
