[Eugenia] Exception loading the resource [message #662716] Thu, 31 March 2011 12:11 Go to next message
Eclipse UserFriend
I just installed Eclipse Helios modelling and from the marketplace I installed Epsilon.

I want to put annotation on my Ecore using the tree editor.

When I try to load the resources from epsilon I get an exception:

Hi,

Could you please try with the latest interim version?

I am not at the office now but tomorrow I will try.
Two questions:
1) Should I use this update site:
http://download.eclipse.org/modeling/gmt/epsilon/interim/
2) Do I need to add some dependecies to the project?

Also using the interim update site I still get the same error.

What should I do to have the gmf annotations on my Ecore meta-model using the tree editor? Should I add some dependecies or create a particular kind of project?

Hi,

Could you please provide a sequence of steps I can follow to reproduce this behaviour and/or send us your metamodel at epsilon.devs gmail com?

Cheers,
Dimitris

Hi, I created a GMF Project on Eclipse Helios 3.6 with two meta-models, one loading the other. When I try to load the registered packages for example "http://www.eclipse.org/gmt/epsilon/hutnConfig" I get the error. I can send the whole project or the meta-models, which are quite simple.

This is one of the two meta-models named basic.ecore:
<?xml version="1.0" encoding="UTF-8"?>
<ecore:EPackage xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" name="Basic"
    nsURI="http://softeng.polito.it/momaapp/basic" nsPrefix="basic">
  <eClassifiers xsi:type="ecore:EClass" name="Named" abstract="true">
    <eStructuralFeatures xsi:type="ecore:EAttribute" name="name" lowerBound="1" eType="ecore:EDataType http://www.eclipse.org/emf/2002/Ecore#//EString"/>
  </eClassifiers>
