JavaMUG this Week: Building a Java-Helidon Application using Github Copilot
Tim.S
Ask GitHub Copilot to build you a Helidon application and it has to guess. Helidon SE or MP? Helidon 3 APIs or Helidon 4? HttpService or Jakarta REST? Explicit composition or CDI? Without framework-specific context it produces code that looks correct, quietly mixes two programming models, and doesn't compile.
That's not a model problem. It's a context problem, and it's fixable.
In this session we'll build a Helidon 4 application with Copilot from an empty directory, a small customer service with routing, configuration, health checks and tests. Along the way, the API changes that trip Copilot up most and how to write a skill for your own framework.
You'll leave able to install the skill, bootstrap a Helidon 4 project with it and write one for the framework your team actually uses.
Suren Konathala is a Senior Technical Program Manager at Microsoft with 26 years in software engineering and enterprise architecture. He wrote the java-helidon skill merged into GitHub's Awesome Copilot project and the Java examples in GitHub's official Copilot SDK cookbook, and contributes to OpenJDK, Jakarta EE, Apache Sling and Oracle Helidon. He writes for Oracle's Helidon publication, is an IBM Champion, IEEE Senior Member. He lives in Frisco.
We'll be meeting at Improving Enterprises, 5445 Legacy Dr #100, Plano, TX 75024
The pizza and networking start at 6:30pm and the meeting at 7pm. Come have a great evening of learning with your fellow local Java enthusiasts.
