I was experimenting with Grails on heroku. I followed this article:
https://devcenter.heroku.com/articles/grails.
Everything works ok.
Then I decided to try a grails app that uses GWT (via gwt plugin).
This time I cannot deploy the application. After git push I get the
following errors:
Compile error during compilation with javac.

I don't have this problem locally. Heroku doesn't see gwt classes. I see
them successfully downloaded during deployment:

I don't understand why gwt classes are not visible.
Did someone succeed with deploying grails + gwt app?
Can someone offer me some advice on how to solve this problem?
I use grails 2.0.3, gwt plugin 0.6.1.
