New firebase json annotations

I'm using autovalue for my entities and annotated them to allow json parsing.

There are new annotations in the new sdk: Exclude, IgnoreExtraProperties, ThrowOnExtraProperties and @PropertyName: https://firebase.google.com/docs/reference/android/com/google/firebase/database/PropertyName. But PropertyName seems to be missing from the sdk..

We missed the @PropertyName annotation in this release of the Firebase SDK for Android, but it was included in a release shortly after.

See this answer for a way to use Jackson explicitly with any version of the Firebase SDK: How to deserialise a subclass in Firebase using getValue(Subclass.class)

BEFORE
@JsonIgnoreExtraProperties(ignoreUnknown=true)
public class ChatMessage {
   public String name;
   public String message;
   @JsonIgnore
   public String ignoreThisField;
}

dataSnapshot.getValue(ChatMessage.class)
AFTER
public class ChatMessage {
   public String name;
   public String message;
   @Exclude
   public String ignoreThisField;
}

dataSnapshot.getValue(ChatMessage.class)
