What's current recommended approach for using Swagger and Ktor? I see there's a few plugins but some don't seem to be being maintained. Also, seems to be a few approaches e.g. auto generate swagger json from routes, or for example visa versa.

We’re going to be discontinuing Swagger support in our plugin (more on that later when we announce plans), and falling back to the Swagger support in the platform (IntelliJ). There is a 3rd party contribution for Ktor and we’ll make sure to contribute to that should it not be maintained.

This is one of the plugins I was looking at for example https://github.com/nielsfalk/ktor-swagger
