I am using the Grails GWT Plugin and have eventually fixed all the compiler errors, except this one: Compiling module com.CalendarMVP | Resolving com.client.mvp.AppPlaceHistoryMapper | Found type 'com.client.mvp.AppPlaceHistoryMapper' | [ERROR] Annotation error: cannot resolve com.client.place.HelloPlace$Tokenizer | java.lang.ClassNotFoundException: com.client.place.HelloPlace$Tokenizer And the same repeats for GreetingsPlace$Tokenizer and UserPlace$Tokenizer, except that I also receive: [ERROR] Annotation error: expected class java.lang.Class, got null This classes are the part of my MVP pattern realization using built-in ActivitiesAndPlaces framework.The code for AppPlaceHistoryMapper is such: package com.client.mvp; import com.google.gwt.place.shared.PlaceHistoryMapper; import com.google.gwt.place.shared.WithTokenizers; import com.client.place.GoodbyePlace; import com.client.place.GreetingsPlace; import com.client.place.HelloPlace; import com.client.place.ManagerCalendarPlace; import com.client.place.ManagerPlace; import com.client.place.UserPlace; @WithTokenizers( { HelloPlace.Tokenizer.class, GoodbyePlace.Tokenizer.class, GreetingsPlace.Tokenizer.class, ManagerPlace.Tokenizer.class, UserPlace.Tokenizer.class, ManagerCalendarPlace.Tokenizer.class }) public interface AppPlaceHistoryMapper extends PlaceHistoryMapper { } And for HelloPlace: package com.client.place; import com.google.gwt.place.shared.Place; import com.google.gwt.place.shared.

I don't think there is anything we can do on our end. You may want to file an issue with the GWT project for this. See: gwtproject/gwt#4657 gwtproject/gwt#7599 kotcrab commented Oct 7, 2015 I hoped it was libGDX issue, it will probably take forever to fix it in GWT and libGDX doesn't even use latest GWT version, right?

Since this error is occurring in the GWT compiler when it tries to evaluate the annotation, there really isn't
