Open API generator for Spring does not (?) support Open API 3 annotations

[aniewielska]

The current situation of OpenAPI 3 vs 3 support:

• TES spec is exclusively in OpenAPI 3
• The current version of TESK uses a new version of OpenAPI Generator for Spring in the form of Maven Plugin
• The generator and plugin accept specification in OpenAPI 3, but the generated annotations correspond to Swagger 2.
• It does not seem at the moment to be possible to generate OpenAPI 3 models or at least it is not straightforward:
• Issue 8703
• Issue 5803
• PR 6306
  and more.
  Additionally, there seems to be now an alternative to SpringFox in the form of SpringDoc
  Verdict: for now TESK will present OpenAPI 2 docs via UI and wait for support of OpenAPI3 in generator or an alternative solution.

Hello! I am not sure if the issue you present here , has anything to do with the issue Im dealing with but it is worth asking , I guess :) We tried to build a new version of tesk-api with TES V1.1: https://github.com/ga4gh/task-execution-schemas/blob/v1.1/openapi/task_execution_service.openapi.yaml . And when we launched the image, Swagger returned this error message "Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Not Found, status=404)."

I found somehwere (https://community.opengroup.org/osdu/platform/home/-/issues/47) that maybe I needed to change the url from $HOST/swagger-ui.html to $HOST/swagger-ui/index.html but then the issue I get is {
"timestamp" : "2023-03-03T18:23:21.278+00:00",
"status" : 401,
"error" : "unauthorized",
"message" : "Full authentication is required to access this resource",
"path" : "/swagger-ui/index.html",
"error_description" : "Full authentication is required to access this resource"
}

Do you have any idea if what you presented above, may have anything to do with the errors we get?
Thanks in advance!
