public interface Project {

}

public abstract class AbstractProject implements Project {

}

public class ProjectImpl extends AbstractProject {

public ProjectImpl(final File rootDirectory)

{ projectRoot = rootDirectory; }

}

@Singleton
public class CurrentProject

{ @Produces @Default @Dependent public Project getCurrent() }

@Inject Project project;

should in this case just consider getCurrent() the only injection source because Abstract class cannot be instantatiated nor can the PRojectImpl since it has no-noarg constructor but does have a constructor with arguments.
