Portlet Dependency always required when Scala cross compiles java #7936

Hi,

we use java and scala in our company and gradle as build tool, and therefore all our sources are stored in src/main/scala I have a very very simple Bean for reproduction:

import com.vaadin.server.communication.ServletBootstrapHandler;

public class JavaTest {

    public ServletBootstrapHandler getHandler() {
        return null;
    }
}

When this bean is contained in the src/main/java no error appears, but if it is available under src/main/scala problems are detected that the portlet-library is not found.

Of course it is possible to add the portlet library but this isn't what we want.

I attached a demo project where the error can be reproduced. Just extract, go in and type ./gradlew clean testClasses
