Hi,
I'm trying to modify a xtext project I created in the new wizard to extend the xbase grammar instead of the terminals. When running the parent pom out of the box all my projects build, but when I update my grammar to include "with org.eclipse.xtext.xbase.Xbase" the maven build breaks with this error below. How do I update the build files to make everything build again?! - Duncan

I found that by adding the snippet below in my generate file I got past the file not found exception in the stack trace I posted in my question:

parserGenerator = {
				antlrParam = "-Xconversiontimeout"
				antlrParam = "5000"
				options = {
					ignoreCase = true
					backtrack = false
					memoize = true
				}
			}

Although running the maven build I get a new error below, but it works fine when i run the generate script. I think I'm close but still driving me crazy.

Caused by: java.io.IOException: The path '/org.eclipse.xtext.xbase/model/Xbase.genmodel' is unmapped

Please compare your setup to the Domainmodel Example. This is an example Xbase based language. Install it with File / New / Examples.

Thanks for the tip, I added the domain model projects in my workspace but when trying to build from the releng pom i get this error.
