### Importing the project into Eclipse

Elasticsearch builds using Gradle and Java 16. When importing into Eclipse you
will either need to use an appropriate JDK to run Eclipse itself (e.g. by
specifying the VM in [eclipse.ini](https://wiki.eclipse.org/Eclipse.ini) or by
defining the JDK Gradle uses by setting **Preferences** > **Gradle** >

7. Commit changes: `git commit -m 'Add amazing feature'`
8. Push to branch: `git push origin feature/amazing-feature`
9. Open a Pull Request

### Code Style

- Use Eclipse formatter configuration (`src/config/eclipse/formatter/java.xml`)
- Follow existing naming conventions
- Add comprehensive JavaDoc for public APIs
- Write unit and integration tests
