I have project created with service-builder artefact. mvn liferay:build-service works perfectly - it is generated sources for services as well as impl-classes in portlet project.
Now, I'd like to generate wsdd to be able to use remote services via SOAP - and got error:

ru.emdev.service.http.FooServiceSoap - is a class from portlet project generated by liferay:build-service
It looks like liferay:build-service is not included portlet classes into classpath
