Hi,

I want to use predefined ecore model instead of inferred ecore model for my grammar. If the predefined ecore model contains reference to JvmTypeReference, "create Xtext project from existing Ecore Models" wizard will generate a very large grammar which can't pass the generation.

Is there a document that provide simple steps guide creating such kind of Xtext project? How to define the grammar and how to write the workflow file?

I defined a very simple ecore model like this:

class Model{
	part Entity[] entities;
}

class Entity{
	String name;
	part JvmTypeReference mapto;
}

Thanks

Did you follow the usual recommendations when it comes to large
grammars? Increase heap, increase generator timeouts, use classplitting
and the like?

Tutorials are available on the website http://www.eclipse.org/Xtext
