Indem Sie von `str` erben, weiß die API Dokumentation, dass die Werte des Enums vom Typ `str` sein müssen, und wird in der Lage sein, korrekt zu rendern.

Erstellen Sie dann Klassen-Attribute mit festgelegten Werten, welches die erlaubten Werte sein werden:

  property is not inherited from a POM to its child: child's POM will use child artifact id if property is not
  set.

  ** since Maven 3.6.1, inheritance can avoid appending any path to parent value by setting model attribute value to
  <<<false>>> for each url:
  <<<project/@child.project.url.inherit.append.path>>>,
  <<<project/distributionManagement/site/@child.site.url.inherit.append.path>>>,

///

/// note

Notice that the input model is still validated.

So, if you want to receive partial updates that can omit all the attributes, you need to have a model with all the attributes marked as optional (with default values or `None`).
