Ginjector interface generated during GWT compilation cannot be found

GoogleCodeExporter commented 9 years ago

I have a project (Mvp4g) where I use a GWT generator to create a 
GInjector. The generator creates this java code: 

public class Mvp4gModuleImpl implements Mvp4gModule { 

    ... 
    @GinModules({com.mvp4g.example.client.Mvp4gGinModule.class}) 
    public interface com_mvp4g_client_Mvp4gModuleGinjector extends 
Ginjector { 
      com.mvp4g.example.client.main.MainPresenter 
getcom_mvp4g_example_client_main_MainPresenter(); 
      com.mvp4g.example.client.main.MainView 
getcom_mvp4g_example_client_main_MainPresenterView(); 
      com.mvp4g.client.history.ClearHistory 
getcom_mvp4g_client_history_ClearHistory(); 

com.mvp4g.example.client.main.historyConverter.MenuHistoryConverter 
getcom_mvp4g_example_client_main_historyConverter_MenuHistoryConverter(); 
    } 

    ... 

    public void createAndStartModule(){ 
      final com_mvp4g_client_Mvp4gModuleGinjector injector = 
GWT.create( com_mvp4g_client_Mvp4gModuleGinjector.class ); 

This works fine with gin-1.0 but when I try it with the gin trunk, I 
got this error: 
16:55:04.235 [ERROR] [mvp4gmodules] Unable to load ginjector type 
[com.mvp4g.client.Mvp4gModuleImpl.com_mvp4g_client_Mvp4gModuleGinjector],

This is due to the move to Java reflection:

Thanks for reporting this. The reason for the problem is that Gin no longer 
loads ginjector definitions from GWT's type oracle and thus can't see freshly 
generated ginjectors. I'm looking into exposing a class loader based on the 
type oracle which would allow us to see any generated code such as the one 
reported in this issue.

Changed title: Ginjector interface generated during GWT compilation cannot be found

GoogleCodeExporter commented 9 years ago

Sorry for the delay - the basic gist of it is that GWT's support is less ideal 
than I'd have liked to. However, I've written a solution that solves this 
problem for now and have thoughts on how to deal with it should GWT change 
their internal representation.
