Vaadin20: Scan Java code from Pom dependency

I want to put a Java class in a Maven artifact that uses the Vaadin @Endpoint annotation (from com.vaadin.flow.server.connect.Endpoint), to use this class in multiple Vaadin projects.

Here is a simple example of such a class:

import com.vaadin.flow.server.connect.Endpoint;
import lombok.RequiredArgsConstructor;
import java.util.Optional;

@Endpoint
@RequiredArgsConstructor
public class SupportInfoEndpoint {

  public Optional<String> getSupportInfo(){
    return Optional.of("mailto:support@my.corp");
  }
}

The Maven artifact includes the source code of the class. What do I have to do so this class is scanned in the using project, by the Vaadin build process, so that

• the corresponding TypeScript code for the frontend is generated
• the class is included in the Spring-Boot application (so the endpoint is actually available at run time)

Is it possible at all?

Unfortunately it is not currently possible, but it will be once #9010 is implemented.

It is my understanding that it is one of the highest priority features to implement for the Fusion team.
