logged errors: "NoSuchMethodError: Operation.<init>(…)" after upgrading to Springfox 3.0.0

After upgrading Springfox from 2.9 to 3.0.0 I see a couple of logged errors when the Spring context is initialized. Note: The context seems to spin-up successfully despite the logged errors.

I’m using using Spring Boot 2.3.2 with the following Springfox dependencies:

+1 same here

well, I fixed it.

I found it because I replaced Operation class in my project for parameter resorting. however the code is old.

Oh, I just realized that I had the workaround for #2705 in place which caused this problem 🤦‍♂️.

Anyway, this might be helpful for others who encounter this issue and don’t realize they have a custom springfox.documentation.service.Operation in their codebase.
