Hello everybody,

I created a simple Xtext project and exported its three generated projects as plugins. Then, I created a Java project which adds the Xtext Nature of my plugin.

I'm able to use Xtext programmatically after loading the model this way:

private Model loadModel() {
		new org.eclipse.emf.mwe.utils.StandaloneSetup().setPlatformUri("../");
		Injector injector = new TGStandaloneSetup().createInjectorAndDoEMFRegistration();
		XtextResourceSet resourceSet = injector.getInstance(XtextResourceSet.class);
		resourceSet.addLoadOption(XtextResource.OPTION_RESOLVE_ALL, Boolean.TRUE);
		Resource resource = resourceSet.getResource(
			    URI.createURI("platform:/resource/JavaX/src/"), true);
		return (Model) resource.getContents().get(0);

Now, I would like to generate code from my model using XpandFacade. This is my code for that:

Model model = loadModel();

        // XPand
        String outputFolder = "output";
        OutputImpl output = new OutputImpl();
        Outlet outlet = new Outlet(outputFolder);

        EmfMetaModel metaModel = new EmfMetaModel(TGPackage.eINSTANCE);
        XpandExecutionContextImpl executionContext = new XpandExecutionContextImpl(output, null);
        XpandFacade facade = XpandFacade.create(executionContext);
        facade.evaluate("templates::Template::main", model.getTables().get(0));

but Im getting the next exception

Exception in thread "main" EvaluationException : No Definition templates::Template::main for tG::Table could be found!
	Internal error : element was null

That template is in the package src.templates of the project (exported as a plugin).

I do not know if the template should be there. The other thing is that while I am able to import the project classes, I can't do that with classes.

I would appreciate any help.

Thank you very much.

are you sure the template uses the emf metamodel? xtext by default uses javabeansmetamodel for the xpand generator project.


Need professional support for Xtext, Xpand, EMF?
