Unable to generate from Arithmetics ex [message #925571]

I seem to be unable to generate Xtext artifact from the Arithmetics example project. The example is installed from the Eclipse new project wizard.

The documentation tells me to right click in the .xtext editor and select "Run As" -> "Generate Xtext Artifacts", but this item is not present in my "Run as" submenu.

In other projects however, such as the State machine example, the menu item is present and generation works fine.

I'm running Xtext 2.3.1.v201208210947 from the update site in Eclipse 4.2.0.v20120528.

What could be the problem?

Thanks for your help.

That menu item is there, and the command ran, but it left me with a lot of "XXX cannot be resolved to a type" compile errors.

It seems like it did not generate the org.eclipse.xtext.example.arithmetics.arithmetics package, where the accual syntax model classes is supposed to go.

Any ideas?

wizard)

Yes, it does.

And I have tried substituting the contents of the Arithmetics.xtext file with the contets from a working project. Still no "Generate Xtext Artifacts" menu item.

What triggers this menu item to appear? Should it be there for all .xtext files? Or does it check that the content of the file is valid Xtext code? Or does it look on other project files?
