Xtext project from existing ecore model [message #695709]

Hi

NB: Using Eclipse Indigo, with the Indigo release Xtext plugin and the project running with Xtext 2 experimental features enabled...

Created a new Xtext project from a fairly simple ecore model (with a newly created generator model) and upon running the MWE2 file it complains that it can't find the interface (that it's supposed to be generating as I understand it).

Caused by: org.eclipse.emf.mwe.core.ConfigurationException: Couldn't find an interface types.TypesPackage
	at org.eclipse.emf.mwe.utils.StandaloneSetup.addRegisterGeneratedEPackage(StandaloneSetup.java:267)
	... 35 more

Note: in the example below I moved my model file into the xtext project, but I've also tried creating a project from scratch which references the ecore model from the project where it originates, with the same runtime exception.

module dk.example.poc.types.TypesDsl

import org.eclipse.emf.mwe.utils.*
import org.eclipse.xtext.generator.*
import org.eclipse.xtext.ui.generator.*

var grammarURI = "classpath:/dk/example/poc/types/TypesDsl.xtext"
var file.extensions = "types"
var projectName = "dk.example.poc.types"
var runtimeProject = "../${projectName}"

Workflow {
	bean = StandaloneSetup {
		platformUri = "${runtimeProject}/.."
		registerGeneratedEPackage = "types.TypesPackage"
	
		// registerGenModelFile = "platform:/resource/dk.example.poc.types/model/Types.genmodel"
	
	}
...

Does anyone have a clue to what's wrong?

Hi, please make sure that dk.example.poc.type exportes the types package and is set as dependency to yourdsls plugin (MANIFEST.MF)

Hi Christian

Thanks for your quick reply, I'm not sure what you mean by exporting the types package (I'm quite new to Eclipse plugin/Xtext).

I basically followed the video from here http://koehnlein.blogspot.com/2010/03/xtext-for-your-ecore-models.html and assumed that it would work Smile

Ah ok, i assumed you'd have basical knowledge of Eclipse Plugin Delevelopment. Can you please post the MANIFEST.MF file of the EMF and the Xtext Plugin

you have basically to check if the emf contains types within the Export-Package: section and the xtext a dk.example.poc.type in the Require-Bundle: section
