How to navigate the complete model of a given project and dsl? [message #721674]

Hi,

in my grammar Entities can reference Entities. These references can of course cross
file boundaries. Now I'm trying to collect all the entities and references between
them to visualize them. The problem is that the links never seem to get resolved.

When using the dsl inside the runtime eclipse application code completion works without a problem across file boundaries.

What I'm doing right now is roughly the following:


        @Inject
	private IResourceSetProvider provider;
	
	@Override
	public Object execute(ExecutionEvent event) throws ExecutionException {
                [snip]
		XtextResourceSet resourceSet = (XtextResourceSet) provider.get(project);
		resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
		
		
		Collection<IFile> resources = null; 
		
		try {
			resources = collectResources(project);
		} catch (CoreException e) {
			e.printStackTrace();
		}
				
		
		for (IFile res : resources) {                             resourceSet.getResource(URI.createURI(res.getLocationURI().toString())
					, true);
		}
		
	        EcoreUtil.resolveAll(resourceSet);
		
		for (Resource r : resourceSet.getResources()) {
			for (Diagnostic d : r.getErrors()) {
				System.err.println(d.getMessage());
			}
		}

which leaves me with a lot of messages like "Couldn't resolve reference to Entity 'Foo'.".

So my question is: how can I make this work? Where should I start to look for possible solutions? Scoping perhaps?

Thanks in advance.

Kind regards,

Alexander

Alex,

When running inside Eclipse, XtextResourceSet.setClasspathURIContext is
set with an IJavaProject to make this work...

Thanks, Ed.

However, I'm trying to do this stuff inside eclipse and afaict the
XtextResourceSet.setClasspathURIContext is being set with an IJavaProject.
