We have many usecases where we need only the direct Resources in Scope of an object, but the transitive hull. (E.g., if we have project dependencies A->B->C) and we want "allResourcesInScope" on A, it should return all resources from A, B and C. (not only A and B).

We have a helper class draft, but it might make sense to put something like this in ScopingResourceSet? (Helper class operates on IProject, please adjust to your needs).

	public static List<Resource>  getAllResourcesInScope(IProject project) {
		TransactionalEditingDomain editingDomain = SphinxUtil.getEditingDomain(project); // Not needed if moving to Scoping Resource Set
		ResourceSet resourceSet = editingDomain.getResourceSet();
		if (resourceSet instanceof ScopingResourceSet) {
			ScopingResourceSet srs = (ScopingResourceSet) resourceSet;
				LinkedHashSet<Resource> hashSet = new LinkedHashSet<Resource>(srs.getResourcesInScope(project));
				boolean modified = true;
				while(modified) {
					modified = false;
					List<Resource> nextRun = new ArrayList<Resource>();
					
					for(Resource r : hashSet ) {
						nextRun.addAll(srs.getResourcesInScope(r));
					}
					modified = hashSet.addAll(nextRun);
				}
				return new ArrayList<Resource>(hashSet);
		} else {
			return resourceSet.getResources();
		}
	}
