Hi @beatngu13, thank for the question!

Is there a way to achieve this with the Quarkus OpenAPI generator?

I will answer below:

generateApis: whether to generate APIs or not.

There is no option for enable/disable the API generation.

apiPackage: which package to use for API classes.

If you want to change the base package in which the classes are generated, use the quarkus.openapi-generator.codegen.spec.<filename>.base-package property.

what exact generator is being used under the hood and how can we supply corresponding configuration options?

Behind the scenesthis tooling uses https://openapi-generator.tech/docs/generators/java/ with microprofile library template.

If I didn't answer your question well, you can tell me and I'll try to improve the answer.
