Swagger overrides Path-Annotations - jax-rs

Question

I just got swagger to produces a valid swagger.json.
I configured swagger by using the Application-config method.
However, as soon as I override the getClasses-Method to add the swagger resouces, my JAX-RS Path-annotated classes stop working.
The method looks like this
#Override
public Set<Class<?>> getClasses() {
Set<Class<?>> resources = new HashSet<>();
resources.add(io.swagger.jaxrs.listing.ApiListingResource.class);
resources.add(io.swagger.jaxrs.listing.SwaggerSerializers.class);
return resources;
}
and invoking super.getClasses() returns am empty set.
I got too many resources in my project, which I would not like to add manually.
Is there any way swagger does not mess with my previous configuration?
Thank you!

You can use a javax.ws.rs.core.Feature. Just register the classes through the callback's FeatureContext. Annotating the feature with #Provider will have it registered through the scanning.
#Provider
public class SwaggerFeature implements Feature {
#Override
public boolean configure(FeatureContext context) {
context.register(ApiListingResource.class);
context.register(SwaggerSerializers.class);
return true;
}
}
But note that if the application is already registering the resources and providers by class-path scanning, I imagine it should also pick up the Swagger classes, as they are annotated with #Path[1] and #Provider[2]. Those are the annotations the class-path scan looks for.
I haven't tried it myself (I stopped using class-path scanning[3]), but have you tried just not registering them at all? In theory the class-path scan should pick it up.
