Description

The template uses the version 0.7.0 of the apollo-data-source package, which is quite old (3 years old). The library has since changed considerably, and I believe users of this generator should enjoy the latest features.

The generated code is incompatible with the latest version (currently 3.6.1), hence this bug report. Additionally, I was not able to compile the code using the old version of apollo-data-source.

The generator as-is, seems to be badly broken and unusable (but do feel free to correct me!)

openapi-generator version

Version 6.0.1; not a regression

OpenAPI declaration file content or url

I'm using EVE Online's ESI for my purposes. Can try to come up with a minimal complete example if required/asked.
