Hi,

I installed Eclipse 3.7 RC3 + Xtext 2.0 and am getting the error below when
I try to generate using my mwe2 file. I am able to generate using the
DomainModel example. I was able to generate using Eclipse 3.6.2 + Xtext
1.0.2 using the same mwe2 file.

Am I missing something?

Hi,

it seems you still have some Xtext 1.0.x stuff installed or on classpath. please make sure that your workflows project has deps to the Xtext 2.0.0 plugins. see Migrating from Xtext 1.0.x to 2.0 from the docs

Hi Mary,

Xtext 2.0 requires Antlr 3.2. Please make sure that the parser generator
is available in exactly that version. The easiest way would be to
install Xtext from http://download.itemis.com/updates/milestones

Regards,
Sebastian

I think this *may* have been due to an incorrect setup in my Target
Platform. It's working now. Thanks for your help!
