Could use more info about how to support jax-rs endpoints

I'm looking at implementing spring contracts in our builds. We have numerous services providing jax-rs endpoints. We have recently provided the ability to provide SpringMVC endpoints, but that is very new and only a handful of services are using that as of now.

I've verified that the contract tests work fine in services that provide SpringMVC endpoints. I was under the impression that Spring Contracts simply doesn't support JAX-RS, but then I read more carefully at https://docs.spring.io/spring-cloud-contract/reference/getting-started/first-application.html, where it specifically refers to "which framework and test type you have set up in your plugin", and it shows simple examples of the generated tests using jax-rs or "webtestclient". However, all it says about how to produce either of these is to "add its library to your classpath". It's not clear which dependency(ies) I have to add to produce jax-rs-based tests. I asked Copilot, and it told me about some "spring-cloud-contract-verifier-jaxrs" dependency, which appears to be a hallucination. From what I can see,

When I ran "mvn help:describe -Dplugin=org.springframework.cloud:spring-cloud-contract-maven-plugin -Ddetail" and I inspected the detailed output in "generateTests", I saw:

    testMode (Default: MOCKMVC)
      (no description available)

I then searched the codebase for this, and I found a little more information. I found a "jax-rs.adoc" file that mentioned a couple of things, like setting the testMode to "JAXRSCLIENT", defining a "WebTarget" instance variable in the base class, and "start a web server". Is this information valid? I didn't see a single check in the code for this testMode value.

Here you have 2 examples of jaxrs apps. Producer and spring producer. Is this useful?

Looks very helpful. I'll dive into that.
