So, you could upgrade Pydantic to the latest version 2, and change the imports to use the `pydantic.v1` submodule, and in many cases it would just work.

		} else {
			nonIPs = append(nonIPs, ip)
		}
	}

	sort.Slice(ipV4s, func(i, j int) bool {
		// This case is needed when all ips in the list
		// have same last octets, Following just ensures that
		// 127.0.0.1 is moved to the end of the list.
		if ipV4s[i].IsLoopback() {
			return false
		}
		if ipV4s[j].IsLoopback() {
			return true

        localRepositoryResolver("${prefix}TestLocalRepositoryPath", localRepository)
    }

    // do not attempt to find projects when the plugin is applied just to generate accessors
    if (project.name != "gradle-kotlin-dsl-accessors" && project.name != "enterprise-plugin-performance" && project.name != "test" /* remove once wrapper is updated */) {
        dependencies {

And if you update that local FastAPI source code when you run that Python file again, it will use the fresh version of FastAPI you just edited.

That way, you don't have to "install" your local version to be able to test every change.

Alles basiert auf Standard-**Python-Typ**deklarationen (dank Pydantic). Es muss keine neue Syntax gelernt werden, nur standardisiertes modernes Python.

is done within Plexus with the configuration supplied with component configuration, but in Maven we take configuration values from the POM. So we have to use the ComponentConfigurator outside of Plexus in order to configure the Maven Mojo which is just a Plexus component. We can use the information from the MojoDescriptor along with the merged configuration information that is now present in the POM to create the complete PlexusConfiguration used to populate values in the Maven Mojo.

You do that with standard modern Python types.

You don't have to learn a new syntax, the methods or classes of a specific library, etc.

Just standard **Python**.

For example, for an `int`:

```Python
item_id: int
```

or for a more complex `Item` model:

```Python
item: Item
```
