        File pluginFile = (pluginArtifact != null) ? pluginArtifact.getFile() : null;
        if (pluginFile == null) {
            throw new IllegalStateException("plugin main artifact has not been resolved for " + getId());
        }

And you only have to declare them once.

Do mesmo modo, você pode sobreescrever o `HTTPException`.

Por exemplo, você pode querer retornar uma *response* em *plain text* ao invés de um JSON para os seguintes erros:

```Python hl_lines="3-4  9-11  22"
{!../../docs_src/handling_errors/tutorial004.py!}
```

/// note | "Detalhes Técnicos"

```Python
from datetime import date

from pydantic import BaseModel

# Объявляем параметр user_id с типом `str`
# и получаем поддержку редактора внутри функции
def main(user_id: str):
    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python

from dirty_equals import IsDict
from fastapi.testclient import TestClient


@pytest.fixture(name="client")
def get_client():
    from docs_src.bigger_applications.app.main import app

    client = TestClient(app)
    return client


def test_users_token_jessica(client: TestClient):
    response = client.get("/users?token=jessica")
    assert response.status_code == 200

        String version = artifact.getVersion();
        String qualifier = formatDate(timestamp, true) + '-' + buildNumber;
