Problem using Swagger Core (v3) to generate OpenAPI with Jersey3 lightweight Grizzly HTTP server

[monsonhaefel]

Hi,

I've been trying, and failing, to use the io.swagger.core.v3 to generate OpenAPI definitions for a working Jersey 3 example running on Jersey's Grizzly HTTP server.  I have included what I believe to be the correct dependencies in the Maven pom but can't seem to find or access any openapi.yaml/json files.   I hate to include it here but I don't see a button for attachments, so here is my maven pom.

Does the Swagger Core (v3) generate OpenAPI definitions when using Grizzly HTTP server included with Jersey 3?  Do I have to create a WAR file to use Swagger Core for this?  What am I missing?
