Hi

Xtext 2.6 is out, but it looks like the latest release of Xcore still
uses Xtext/Xbase 2.5... at least the current version does not work with
Xbase 2.6

The main error is due to

Caused by: java.lang.ClassNotFoundException:
org.eclipse.xtext.xbase.services.XbaseGrammarAccess$XExpressionInsideBlockElements
cannot be found by org.eclipse.emf.ecore.xcore_1.1.2.v20131212-0836
at
org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:501)

org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:421)

... 162 more

Is Xcore already being ported to Xtext 2.6?

thanks in advance
Lorenzo

Lorenzo,

Where are you getting the Xcore build from?

Hi,

I used the Xcore version for Luna M7 and had a similar problem when
updating to new Xtext 2.6 release. Xcore didn't have a corresponding
official update, but switching to the nightly build worked. It would be
good of there also was an update at the Luna site.

Yes, we've submitted the builds for the next RC version of Luna, at
which point they should be lined up properly. Both Xtext and EMF
(including Xcore) are released and should function well together...

I was using Xtext composite update site and Kepler update site.

Then I tried with the EMF milestones update site and it worked like a
charm :)
sorry for not getting back earlier about that.

cheers
