return null // If we already failed with these credentials, don't retry.
     }
    ```

    You may also skip the retry when you’ve hit an application-defined attempt limit:

    ```kotlin
    if (response.responseCount >= 3) {
      return null // If we've failed 3 times, give up.
    }
    ```

    This above code relies on this `responseCount` extension val:

Agora, se você verificar a documentação, ela exibirá todos os metadados adicionais:

### Ordem das tags { #order-of-tags }

A ordem de cada dicionário de metadados de tag também define a ordem exibida na interface de documentação.

Por exemplo, embora `users` apareça após `items` em ordem alfabética, ele é exibido antes deles, porque adicionamos seus metadados como o primeiro dicionário na lista.

Each platform and module has its own source directory under [platforms/](../platforms).
In these source directories, you will find the Gradle projects that make up the platform or module.

The platforms and modules are defined using a DSL in [settings.gradle.kts](../settings.gradle.kts)
