Hi Zoltan,
please make sure that your resource set was configured properly, e.g. by
using the IResourceSetProvider

Hi Sebastian,
thanks for your quick answer. Using IResourceSetProvider I managed to open the model; however, the resulting code depends on UI projects (the interface itself is defined in the org.eclipse.xtext.ui project).
For our usage this is not the best direction, we also want to use the parser in a headless environment, but with Eclipse plug-ins available (so e.g. EMF packages are registered using activators; eclipse extensions are available).
Following the direction I initialized a standalone setup, and then asked for the corresponding resource set using the following code:
Injector injector = new EMFPatternLanguageStandaloneSetup()
.createInjectorAndDoEMFRegistration();
if (file == null)
return null;
ResourceSet resourceSet = injector.getInstance(ResourceSet.class);
URI fileURI = URI.createPlatformResourceURI(file.getFullPath()
.toString(), false);
Resource resource = resourceSet.getResource(fileURI, true);
My question would be whether this shall work in all cases, or this setup might cause some issues in the future (e.g. is it any problem that the createInjectorAndDoEMFRegistration method are called multiple times?
Thank you again,
Zoltán Ujhelyi
