I want to create a simple "news api" in scala-play where the server stub is generated with the openapi scala-play-server generator. (Therefore i use this https://drive.google.com/file/d/1Qez3JcdaBPNVq1BAWrgcS_sbyDrxAQKM/view?usp=sharing openapi file)
The following command is used to generate the project:
openapi-generator generate -g scala-play-server --additional-properties=basePackage=de.hwrBerlin.lehre.effort.newsapi,apiPackage=de.hwrBerlin.lehre.effort.newsapi.generated.api,modelPackage=de.hwrBerlin.lehre.effort.newsapi.generated.model -o api -i openapi.yaml
But when i start to run the project with sbt run and then open localhost:9000 i get several errors:

It seems like a many issues are missing but i have no idea how to fix the issue except doing it manually. I use windows 10 and the AdoptOpenJDK version "11.0.8"
This issue is a bug in the current openapi-generator version (4.y.z). I opened an issue on github:
https://github.com/OpenAPITools/openapi-generator/issues/7371
and wing328(Core team and founding member of OpenAPI Generator) suggested using the 5.0.0-beta2 of the openapi-generator. This fixed all import and dependency issues.
