Pydantic also has [`BeforeValidator`](https://docs.pydantic.dev/latest/concepts/validators/#field-before-validator) and others. 🤓

        String distribution = System.getProperty('tests.distribution', 'default')
        // The distribution can be configured with -Dtests.distribution on the command line
        project.testClusters.matching { it.name.equals("integTest") }.configureEach { testDistribution = distribution.toUpperCase() }

There are some additional dependencies you might want to install.

Additional optional Pydantic dependencies:

* [`pydantic-settings`](https://docs.pydantic.dev/latest/usage/pydantic_settings/) - for settings management.
* [`pydantic-extra-types`](https://docs.pydantic.dev/latest/usage/types/extra_types/extra_types/) - for extra types to be used with Pydantic.
