Can't add RestClient as a dependency

[andreasjy]

I have a project which consists of api and implementation part. I would like to use the api part as a dependency in another project to make api calls towards the first project.
When I annotate the api interface with @RegisterRestClient the second project doesn't seem to be able to scan the file for annotations. I tried using scan-libraries option in config.yaml to point the scanner towards my jar but that didn't help.
Is it something that is not supposed to be done or is there a way to get it working?
