Dagger2 generated class is all of a sudden missing from Android Studio

Question

I have been using Dagger2 in Android Studio for months now but today all of sudden it stopped working and is giving me the following error

 error: cannot find symbol
        return Dagger_Injector.builder()
               ^

symbol:   variable Dagger_Injector
  location: class Initializer
Note: Some input files use or override a deprecated API.

1 error

Here is the code where it is failing

@Singleton
@Component(modules = {TestService.class, ServiceFactory.class})
public interface Injector {

    public final static class Initializer {

        public static Injector init(ApplicationLoader app, boolean bypassVerification) {
            return Dagger_Injector.builder()
                    .testService(new TestService())
                    .serviceFactory(new ServiceFactory(app))
                    .build();
        }

    }

    void inject(ApplicationLoader obj);
}

Here is my gradle info

Any help is appreciated.

Answer 1

So it looks like for some reason there are no more underscores in names of generated component classes. Just look into yours build/generated/source/apt folder to see it really changed this way.

Fix it by replacing Dagger_Injector with DaggerInjector etc.
