How to Create Java Project with Maven in Eclipse - Step by Step Guide

If you are not using Maven for managing dependency and creating a build for your Java project, then you are definitely missing something. Being an ardent fan of ANT, I started with Maven quite late, but once I started, I haven't looked back. Maven makes it so easy to add new open-source JAR files, building and testing your project that you wouldn't look back. By the way, like all the things starting is difficult. I spent countless hours will creating my first Java project using Maven and Eclipse, but those were days with older Eclipse IDE. Now with Eclipse Juno and indigo, you get inbuilt support of Maven, which means it's a lot easier to start working with the Maven-based Java project in Eclipse IDE.

In this article, we will see step by step guide for setting up Maven for Eclipse, updating Maven proxy settings, Installing M2Eclipse plugin and finally creating Maven-based Java project in Eclipse.

Btw, if you are just starting with Maven, I suggest you to first go through a comprehensive Maven course like Apache Maven: Beginner to Guru to learn some fundamentals. It will not only help you to build and deploy your Java and Spring Boot projects using Maven but also learn Maven itself in depth.




How to Setup Maven in Eclipse?

Before creating a Java project using Maven in Eclipse, you first must set up your Eclipse with the correct plugin. If you are starting it fresh then you can follow below steps

1) Download Eclipse IDE, both Juno and Indigo will work.

2) Install Maven Integration for Eclipse Plugin, you can install this by searching for it on Eclipse Market Place.

3) Restart Eclipse

When you install Maven plugin, they come with bundled apache Maven and they create Maven repository in your User directory like C:\Users\YourUserName\.m2\repository. This means you don't need to manually download and install Apache Maven by yourself.

By the way, if you are running under proxy than, you need to update Maven's settings.xml file, without this Maven will not be able to download dependencies and plugins when required.

To update Maven's Internet connection proxy settings, you can edit the following block of Maven settings.xml. This file can be found inside C:\apache-maven-3.1.0\conf\settings.xml or your specific download folder if you are not using embedded Maven, otherwise in location C:\Users\YourUserName\.m2\settings.xml.

        http
        proxyuser
        proxypass
        proxy.host.net
        80
        local.net|some.host.com



Once you are done with your changes, you can save settings.xml, but remember to click the update settings button on Eclipse, otherwise, your changes will not be picked up by Eclipse and you will spend countless hours on mysterious Maven issues, which hardly direct you here.

2. How to Create a Maven-based Java project in Eclipse?

Now, we are ready to start. It's very easy to create a Maven-based Java project, once you have set up Maven and installed Maven Integration plugin for Eclipse. Here are the steps to follow

1) Create New Project, and choose Maven -> Maven Project

2) Select simple archetype and default workspace location, you can choose any workspace location or archetype but for this demo, default settings are good enough.

3) Put meta details for a project like groupId, artifactId, project name, etc.

4) Done, your project is created, you can view them in Project Explorer.



That's all folks. You can see how easy it is to create a Maven-based Java project in Eclipse. You can also follow the same steps if you are still using Eclipse Indigo. The key thing is to install the Maven Integration Plugin for Eclipse, also known as M2Eclipse. This makes your life much easier, and once you start working with Maven, you will not going to turn back, because Maven does a fantastic job on managing dependencies, downloading JAR files and libraries.

Enjoy working with Java, Maven, and Eclipse and let me know if you face any issue while creating a Maven-based Java project in Eclipse IDE.
