Is there a standard implementation for a GSON Joda Time serialiser?

I'm using GSON to serialise some object graphs to JSON. These objects graphs use Joda Time entities (DateTime, LocalTime etc).

The top Google hit for "gson joda" is this page:

• https://sites.google.com/site/gson/gson-type-adapters-for-common-classes

It provides source for a type adapter for org.joda.time.DateTime. This link is also what is referenced in the GSON User Guide.

I expected to find a pre-rolled library that included joda-time serialisers that I could reference as a Maven dependency - but I can't find one.

Is there one? Or am I forced to replicate that snippet in my own project?
