Hi,
I am trying to migrate some Xtext projects to 2.3 and I have encountered the following problem.
When trying to run the Main class I load a resource I wish to link to via the resource set as follows
Resource resource2 = set.getResource(URI.createURI("src/xxx.mydsl"), true);
i.e.
protected void runGenerator(String string) {
// load the resource
ResourceSet set = resourceSetProvider.get();
Resource resource2 = set.getResource(URI.createURI("src/xxx.mydsl"), true); Resource resource = set.getResource(URI.createURI(string), true);
// validate the resource
List<Issue> list = validator.validate(resource, CheckMode.ALL, CancelIndicator.NullImpl);
if (!list.isEmpty()) {
for (Issue issue : list) {
System.err.println(issue);
}
return;
}
// configure and start the generator
fileAccess.setOutputPath("src-gen/");
generator.doGenerate(resource, fileAccess);
System.out.println("Code generation finished.");
}
This code runs with our current Xtext installation (Xtext SDK 2.2.1.v201112130541) but not with Xtext SDK 2.3.0.v201206051055 .
I have tried to track down the problem and it seems the new code modifies the StateBasedContainer created by the DefaultGlobalScopeProvider to a DescriptionAddingContainer, which then leads to a SelectableBasedScope with a selectable of FilterUriContainer (old code selectable = StateBasedContainer).
Now I am out of my depth  I have no idea why this is not working.
I have attached a couple of example projects, the Main in MyDsl1 runs with Xtext 2.2 and not with 2.3 (linking error).
Any help/hints as to what I am doing wrong would be appreciated.
Note : Everything works fine inside Eclipse.

Andrew,
could you please add information about the actual problem that you face?
What does not work for you? Do you get exceptions?
Regards,
Sebastian
