on plugin goals execution order:

   * <<in a given phase, goals order is not expected to be guaranteed nor finely tuned>>:
     it is just a consequence of the order obtained during {{{../maven-model-builder/}effective model building}},
     which combines profile activation+injection and inheritance assembly from parents,

   * known limitations are notably that:

## Nested Models { #nested-models }

Each attribute of a Pydantic model has a type.

But that type can itself be another Pydantic model.

So, you can declare deeply nested JSON "objects" with specific attribute names, types and validations.

All that, arbitrarily nested.

### Define a submodel { #define-a-submodel }

For example, we can define an `Image` model:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[7:9] *}

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

  <artifactId>child-artifact-id</artifactId>
  <version>11-SNAPSHOT</version>
  <name>Model inheritance test parent: module directory != artifactId</name>
  <description>
    artifactId == "child-artifact-id"
    but expect path on SCM and site == "child"
    feature: support "project.directory" property, ressembling future model addition of "directory" element along "artifactId"
