Anders say Gson is included in the SDK, and indeed the release note said so.
But I needed to add the .jar from Gson by my own in order to example code works.
I might be missing something, if so let me know. If not check it please.
EDIT: I found the gson lib in the SDK. But I was using TET lib as an external JAR so gson was not been found.
I suggest to clarify this when you say here: "To use the SDK you can either link the SDK project to your own Java project or simply export the SDK to a Jar file and add the library."
