Description

The issue was initially reported in Micronaut, but it turns out to be a bug in Groovy: https://github.com/micronaut-projects/micronaut-core/issues/7189

The problem is Groovy incorrectly resolving the @Client annotation on the TestClient interface to the inner interface instead of the imported annotation.

The code below illustrates the bug. It fails to compile.

@Grab("io.micronaut:micronaut-http-client-core")
import io.micronaut.http.client.annotation.Client

class Application {
    static interface Api {
         static interface Client extends Api {}
    }
    
    @Client("/")
    static interface TestClient extends Api.Client {}
}

println Application.TestClient.annotations
