@AutoFactory classes should not be @Inject-ed, inject the generated factory instead. Classes that are annotated with @AutoFactory are intended to be constructed by invoking the factory method on the generated factory. Typically this is because some of the necessary constructor arguments are not part of the binding graph. Generated @AutoFactory classes are automatically marked @Inject - prefer to inject that instead.
Suppress false positives by adding the suppression annotation
@SuppressWarnings("AutoFactoryAtInject") to the enclosing element.
