## Development Commands

### Setup
```bash
mvn antrun:run          # Download OpenSearch plugins (required before first build)
mvn dbflute:download    # One-time setup for DBFlute
mvn dbflute:freegen     # Generate DBFlute source code
mvn license:format      # Add license headers
```

### Build

Clicking okay on the dialog will cause a copy of the `accepted-public-api-changes.json` containing your (properly sorted) addition to be downloaded.
You can then replace the existing file with this new downloaded version. 
### Java Toolchain
