Reference to EClass cannot be resolved in Juno Modelling + Graphiti + Spray

[GoogleCodeExporter]

I installe Spray according to  
https://spray.ci.cloudbees.com/job/spray-docs-build/lastSuccessfulBuild/artifact
/docs/org.eclipselabs.spray.doc.user/docs/html/SprayUserGuide.html#InstallSpray
with 3rd party dependencies on a fresh Eclipse Modelling Edition Juno Service 
Release 1 (except for one update of the modelling tools) on OS X 10.8.2.
After installing the 3rd party dependencies I was repeatedly facing blocking 
errors during installation of spray from an archive downloaded here 
(spray-0.4.0) which all looked like this:

Cannot complete the install because of a conflicting dependency.

After uninstalling MWE 2 language SDK, Xtext SDK, Xtext examples and Xbase i 
was finally able to install spray.

But when i tried to do the tutorial in the Spray user guide (New Spray Project 
on epackage at http://www.mod4j.org/busmod with diagramm for class 
BusinessModelDomain) the line

import BusinessDomainDsl.*
diagram busmod for BusinessClass

would result in a @Reference to EClass cannot be resolved. It seems a lot like 
issue 135, which was supposed to be fixed on juno branch, but I still have the 
same problem.

?

Sorry, the code i provided is not 100% correct, the error occurs on

import BusinessDomainDsl.*
diagram busmod for BusinessDomainModel

version 0.4.0 only works with Eclipse Indigo and does not include the fix for 
resolving the EClasses.

Instead you should use

3rd party:
https://spray.ci.cloudbees.com/job/spray-ci-targetplatform/lastSuccessfulBuild/a
rtifact/releng/org.eclipselabs.spray.repository/target/repository/

Spray:
https://spray.ci.cloudbees.com/job/spray-assembly-build/lastSuccessfulBuild/arti
fact/releng/org.eclipselabs.spray.updatesite/target/repository/

Maybe it is even required to download the zip files instead of using the URLs 
directly.
