Quick steps to build: 1. Install JDK 17. 2. Install Gradle (or use the Gradle wrapper if added). 3. Update versions in build.gradle if needed. 4. Run: `./gradlew build` 5. Drop the generated `build/libs/hellomod-1.0.0.jar` into your Fabric mods folder. Notes: - This is a minimal template. For a real mod, add textures (resources/assets/hellomod) and proper item models. - Adjust Fabric Loader / Fabric API versions in build.gradle to match the latest compatible versions if you encounter dependency issues.
