Galileo: Fatal error in eclipse following xText tutorial [message #55249]

I'm following the xtext tutorial
(ttp://www.eclipse.org/Xtext/documentation/latest/xtext.html) in Galileo
(Clean install, eclipse-modeling-galileo-incubation-macosx-cocoa) but when
I need to generate the language artifacts, as mentioned in Generate
language artifacts, I need the Antlr generator fragment...

----- Console message
The Antlr generator fragment couldn't be found on the classpath.
It is highly recommended to install it using the external updatesite:
'http://download.itemis.com/updates/'.
...
http://download.itemis.com/updates/milestones
----- End Console message

When I use the mentioned update site
http://download.itemis.com/updates/milestones and restart eclipse, eclipse
produces a startup error in the log:

java.lang.ClassNotFoundException:
org.eclipse.core.runtime.adaptor.EclipseStarter

Eclipse won't start any more... I need to manually remove the installed
features and packages, or replace the installation with a fresh one...
I've tried various releases in the update site.

Where can I get the 'Antlr generator fragment' for Galileo
(eclipse-modeling-galileo-incubation-macosx-cocoa) if it's not included
already?
Is there another way to continue the tutorial?

Does anybody else have the same problems?

Hi ronald,
Looks like you've installed an older version.
The update site to use with 3.5 is http://download.itemis.com/updates/
not the */milestones one.
I've updated the update site right now. Also cleaned up the milestones
sub site, so one can't get the older unsupported feature versions.

Please update.

Best regards,
Dennis.

Dennis,

Thanks for the quick reply!
Version 0.7.0.200907031240 seems to work fine.

I now can continue my journey in the DSL/xText world :)
