Hi all,
we just ran into a strange issue where an otherwise well-functioning Xtext editor suddenly reports several Guice provisioning errors, all of which seem to boil down to an xmi.ClassNotFoundException that says "Class 'EClass' is not found or is abstract." I am rather stumped, because I imagine that pretty much nothing would work if EClass is not on the classpath. All provisioning errors have to do with either the ValueConverterService or the DefaultHiddenTokenHelper. Unfortunately, we don't know how to reproduce this problem.
Any ideas what might be going on or how we could further diagnose it?
Has anyone else seen these "Class 'EClass' is not found or is abstract." error?
Thanks for any suggestions,
Mirko

Hi Mirko
Seems familiar, but it was some time ago; Xtext diagnostics and URI
tolerance have steadily improved.
I strongly suspect meta-model schizophrenia; the same meta-model being
loaded twice under 'different' access URIs and so with two to choose
from, the left-hand one looks bad when the right-hand one is needed.
EClass can be found as its compiled instance
http://www.eclipse.org/emf/2002/Ecore#/EClass is usually the compiled
instance
platform:/resource/org.eclipse.emf.ecore/model/Ecore.ecore#/EClass can
deviate
platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore#/EClass can deviate
.../../org.eclipse.emf.ecore/model/Ecore.ecore#/EClass is very fragile
Correct initialisation of EcorePlugin.getPlatformResourceMap() can fix
up some platform:/... paths in a standalone environment; see MWE2's
StandaloneSetup. EMF's deresolved relative access is quite hard to fix
for arbitrary starting locations, particularly those resulting from the
more distributed Workspace that GIT encourages.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=361063
contributes a new Class to EMF to make initialisation to support
explicit and implicit platform: URI accesses almost trivial. This
perhaps solves the initialisation problem.
Helpful diagnosis of meta-model schizophrenia requires a combined
ResourceSet and EPackage registry scan for EPackages that share an
nsURI. Xtext now has something resembling this to diagnose problem
import statements.
Regards
Ed Willink

Hi Mirko,
please double check for suspicious URIs in the YourLang.xmi that is used
by the grammar access. Ed compiled a nice list of faulty patterns so
basically only http:// uris should be used to refer to EClass.
Did you regenerate the languages before these problems occurred or did
you install an update or something?
Regards,
Sebastian
