@SimY4 this looks quite good. The only problem you have (and the reason the build fails) is on codestyle on the test. If you run the build locally, you'll see it formats it automatically and hence there's a difference (and hence it is not ready for merging). Can you fix that formatting and I can then merge the pull request. Happy to release it after that.

@SimY4 - I merged your changes into my fork and made the formatting changes (you potentially have to skip gpg signing if you want it to work correctly - depending on your setup).

I created a pull request into your fork for the changes so you can use them and update this PR:
https://github.com/SimY4/feign-annotation-error-decoder/pull/1

Once the changes are made it will allow me to easily merge and release.

@saintf good to go

Thanks again for reviewing this PR.
