Following the tutorial, confused on how I actually generate any Java code [message #1052041]

Hi,

I have been following the 15 min tutorial and have created my Grammar, generated the artifacts and ran this as a new eclipse application which seems to work fine.

However when I move onto the extended tutorial and create my code generator in the Xtend file and then run my Xtext project as a new eclipse application I don't understand how to generate the Java classes.

The tutorial says 'Now simply create a new source folder src-gen in the that project and see how the compiler will pick up your sample Entities and generate Java code for them.'

I don't understand what I'm missing here or what I need to do to generate the Java code, I just have an empty file in my src folder at the moment.

What exactly do I need to do?

Thanks

Ok

I see in my package explorer the src-gen file which contains my .java files.

However If i try to open these eclipse will just freeze and I have to manually terminate application from the main eclipse application.

maybe you should start runtime eclipse with -XX:MaxPermSize=128m
