I want to generate a class with a super class, how do I do this with JvmModelInferrer?
The "superTypes +=" generates an "implements" clause but I need an "extends" clause.
Which variable I can use for that?

supertype += ...

Is unknown.
and

superTypes += ...

Does produce an "implements" clause.
2)
In the "isPreIndexingPhase = false" phase.

i cannot reproduce this

domainmodelexample:

class DomainmodelJvmModelInferrer extends AbstractModelInferrer {
	
	@Inject extension JvmTypesBuilder
	@Inject extension IQualifiedNameProvider

	def dispatch infer(Entity entity, extension IJvmDeclaredTypeAcceptor acceptor, boolean prelinkingPhase) {
		accept(entity.toClass( entity.fullyQualifiedName )) [
			documentation = entity.documentation
			superTypes += "demo.AbstractEntity".typeRef
		]
	}
	
}

I discoverd that the "superTypes +=" does not work correctly if the referenced type could not be found in the generators context.
May this be a bug ?

What do you mean by generators context

The context in which the generator runs including the generated classes.
