### Pydantic v1 y v2 en la misma app { #pydantic-v1-and-v2-on-the-same-app }

**No está soportado** por Pydantic tener un modelo de Pydantic v2 con sus propios campos definidos como modelos de Pydantic v1 o viceversa.

mvn test                       # Run tests
mvn formatter:format           # Format code
mvn license:format             # Update license headers

### Code Style

- 4 spaces (no tabs), opening brace on same line, max line length 120
- JavaDoc required for public APIs
- License headers required (Apache 2.0)

### Testing

- **Structure**: `src/test/java/org/codelibs/fess/crawler/`

### Aynı Uygulamada Pydantic v1 ve v2 { #pydantic-v1-and-v2-on-the-same-app }
