Manu Zhang updated GEARPUMP-375:
--------------------------------
Description:
The current version of Upickle (0.3.4) has no scala 2.12 support while the
latest version (0.6.5) needs users to define a serializer in a case class's
companion object. It will a lot of effort to define those serializers given the
number of case classes we have in Services module.
I propose we switch to Json4s, a facade for various scala json libraries, which
supports scala 2.12 and can serialize case class out of box
The only concern could be that Json4s has no [Scala.js
support|https://github.com/json4s/json4s/issues/256] yet but we are not using
Scala.js anyway
