Resource 'xxx' does not exist [message #1065637]

Hi all,
apologies in advance for the basic question.
I created 2 projects:
1) Project1, which is a GMF diagram project that uses an Xtext resource whose grammar is defined in Project2
2) Project2, which defines the grammar of the resource used in Project1.

Obviously Project1 imports Project2.

This is the code that I use in Project1 to access to the resource:

new EventStandaloneSetup().createInjectorAndDoEMFRegistration();
ResourceSet rs = new ResourceSetImpl();
Resource resource = rs.getResource(URI.createURI(path+"/Domain.event"), true);
return resource.getContents().get(0);

Can anyone help me to solve this problem?
Thank you in advance!

The exception I get is the following:

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.core.internal.resources.ResourceException: Resource '/Users/liliana/Documents/Work/DigitalForensics/openpf-Jun/openpf/runtime-EclipseApplication/ForensicsExample/Domain.event' does not exist.

Hi you should never ever call standalone setup from eclipse.
http://koehnlein.blogspot.de/2012/11/xtext-tip-how-do-i-get-guice-injec
tor.html?m=1
Then you should you platform resource URIs.
Use IResourceSetProvider to obtain a resource set.
And then the depending project should have a pependeny (reference) to
its dependenybprojectb( see projects properties context menu)

Hi Christian,
thank you very much for your help and sorry again for another silly question.
Actually, I do not know how to obtain a IResourceSetProvider.
I guess a "default implementation" should be created by the Xtext generator XXXUIModule class.

How can I get a IResourceSetProvider?

Thank you

Hi Christian,
I injected a ResourceSetProvider, but am actually having another problem.

The get method of the ResourceSetProvider requires an IProject as parameter.
Since this is a plugin for another application, I cannot get the IProject from the current workspace, because the resource come from a different workspace.

Any additional help?

Thank you

Yes, I am executing an action in Eclipse,
but the project from which the action is executed is from a workspace (runtime-EclipseApplication) that is different from the workspace where the xxx.diagram project (which contains the code of the executed action) was developed.
Since to get a resource with a ResourceSetProvider you need to pass the IProject as an argument, I do not have idea how to get this IProject.

Thank you again for your help!

Hi Christian,
apologies, my fault. Sad

The resource is located in the same project so I do not have problems anymore in getting the IProject.
The next issue is that the injected ResourceSetProvider is null.
Do I have to initialize it? I will also have a look at the blog post anyway.

Thank you for your patient.

Hi Christian,
I use this to inject the ResourceSetProvider

EventActivator.getInstance().getInjector("org.forensics.simpEvent.Event").injectMembers(this);

it worked perfectly!

Thank you very much Smile
