Thanks @mimaison!
- Do you have any plans for generating some HTML from the YAML?
- What about documenting the expected non-200 response codes?

Should we mention includeTasks and onlyFailed parameters?

I've added descriptions for these parameters

Mention the semantics of pausing an already paused connector.

I think nothing happens when pausing an already paused connector. Isn't it the case?

I think you're right, but then we should say that it's idempotent.

Again, we should explain what happens if you resume a non-paused connector.

It's not just about the cluster, it's also info about this particular server.

| @Operation(summary = "Get details about this Connect worker and the id of the Kafka cluster it is connected to") |

It also depends on having the connect runtime classes/jar.

I believe this happens automatically because of classpath = sourceSets.main.runtimeClasspath

The Response return types in this and other Resource classes means there are no schemas generated, which seems less than ideal.

Yes this is not great. I think this should be fixable without requiring a KIP, but let's do this in a separate PR

We should explain the behaivour of the connectorsOnly parameter too

Thanks @tombentley for taking a look!
I did take a look at generating HTML when working on this weeks ago but I did not find any generators that I really liked. I tried the htnl, html2 and dynamic-html generators from https://openapi-generator.tech/docs/generators#documentation-generators but found they were either buggy or required quite a bit of template customization to be nicely readable. So for now I'm sticking to only generating the spec file.
Yes definitively something we need to do. I'm tempted to do it in a separate PR where we'll also use types that describe the response schemas. |

Modulo the idempotency comment this LGTM. +1 for a follow which adds the response codes and documents the response schemas better.
