Most of what I write is on TheServerSide.
If you ever wanted to feel like a professional while also secretly trusting the internet not to erase your work this guide walks you through using Git and GitHub with Maven inside Eclipse. It covers the essentials from local repo to remote push and automated builds with a dash of real world sarcasm and zero command line worship required.
Gather these bits like a practical hoarder. You will need Eclipse with EGit and Maven support installed, a Java JDK configured in Eclipse, and Git installed on your machine. Also set your Git user name and email with global config so your commits stop looking anonymous.
If you prefer the command line life then run these from your project folder.
git init
git add .
git commit -m "Initial commit"
If you like GUI magic use Eclipse Team menu to share the project with Git. EGit will create the local repository and wire up the project metadata for you. Either way commit messages should be human readable so future you does not rage.
Create a repository on GitHub using the website. Back in your terminal or in Eclipse add the remote and push the main branch.
git remote add origin <repository URL>
git push -u origin main
Use SSH keys or a personal access token for authentication. SSH keys are the least awkward once they are set up. A personal access token works well with HTTPS when your network or tooling refuses to behave.
Make sure your pom.xml contains the usual groupId artifactId and version. Declare dependencies for compilation and testing and add plugins for building packaging and reporting as needed. Keep the POM tidy so build automation does not develop an existential crisis.
pom.xmlEclipse has Maven support so you can update the project run Maven goals and resolve dependencies without leaving the IDE. Use the context menu Run As Maven build for specific goals and use Maven update to refresh Eclipse project settings from the POM.
The Team perspective and Git history views let you make commits stage changes and push without performing a ritual at the command line altar. That said knowing a few commands keeps you from being surprised when the GUI does something mysterious.
mvn clean package
mvn test
git branch feature/name
git checkout feature/name
git push -u origin feature/name
Create a feature branch for each unit of work then push it and open a pull request on GitHub for review. Protect the main branch with required checks and merge only after tests pass and reviewers stop asking for tiny changes.
Hook your GitHub repository to a CI system that runs Maven builds for every PR. This catches failures early and gives reviewers something boring to rely on. Use automated checks that run mvn test and a packaging step so merges do not surprise your release pipeline.
Keep commits focused and messages meaningful. Use the POM to centralize build configuration so local builds match CI. If you use the Maven wrapper include the wrapper files in the repo so colleagues do not invent new local Maven versions like they were collecting vintage stamps.
There you have it. With Git GitHub Maven Eclipse and a smidge of patience you can run a sane version control and build automation workflow for Java projects. Now go commit something that future you will thank you for.
