Scope annotation on implementation class of AssistedInject factory is not allowed
Classes that AssistedInject factories create may not be annotated with scope annotations, such as @Singleton. This will cause a Guice error at runtime.
See [https://code.google.com/p/google-guice/issues/detail?id=742 this bug report] for details.
Suppress false positives by adding an
@SuppressWarnings("GuiceAssistedInjectScoping") annotation to the enclosing element.
