Inspiration
While learning Java, I noticed that one of the biggest struggles for beginners is understanding compiler errors. Most error messages are written in technical language, and beginners often don’t understand what actually went wrong in their code. Instead of learning programming concepts, students spend a lot of time searching for solutions online. This inspired me to build something that could automatically detect errors and explain them in simple language.
What it does
Smart Java Debug Helper automatically detects errors in Java code and helps beginners understand them. Whenever a user pushes code to the repository, the project’s automated pipeline compiles the Java files and checks for syntax or compilation errors. If an error is detected, the system generates an explanation in simple, beginner-friendly language and suggests how to fix it. This makes debugging easier and faster for students who are just starting to learn Java.
How we built it
This project was built using GitLab’s CI/CD pipeline along with AI assistance. The pipeline automatically compiles Java files using a JDK environment and stores any error messages. If errors are found, the system creates an issue in the repository and sends the error message for explanation. The goal was to create a simple but useful workflow where beginners can push their code and immediately understand what went wrong.
Challenges we ran into
The biggest challenge was setting up the automated pipeline correctly and making sure the system could detect errors properly. Integrating AI features with the project and configuring triggers was also difficult because it required learning new tools and features in a short time. Since this was my first solo hackathon project, understanding how everything works together was a challenge, but it also helped me learn a lot.
Accomplishments that we're proud of
The biggest accomplishment is building a working AI-based debugging assistant from scratch as a beginner. Even though it started as a simple idea, the project now automatically detects errors and helps beginners understand them. Completing the full workflow — from writing the idea to building the pipeline and testing it — was something I’m really proud of.
What we learned
Through this project, I learned how CI/CD pipelines work, how automated error detection can be implemented, and how AI can be used to improve the learning experience for beginners. I also learned how to structure a project properly, write documentation, and work independently on a complete idea from start to finish.
What's next for Smart-Java-Debug-Helper
In the future, this project can be improved by supporting runtime errors, adding support for more programming languages, and making the explanations even more interactive. It can also be turned into a beginner-friendly learning tool that helps students understand programming errors step by step instead of feeling frustrated by them.
