How can I add the Play JSON library (play.api.libs.json) to my sbt project?
When I added the following to my plugins.sbt file:
addSbtPlugin(\"play\" % \"sbt-plugin\" % \"2.1.0\")
I faced this error:
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: UNRESOLVED DEPENDENCIES ::
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
[warn] :: play#sbt-plugin;2.1.0: not found
[warn] ::::::::::::::::::::::::::::::::::::::::::::::
I did not find a resolver for this library, otherwise I would\'ve added it and ran sbt update. Note that my resolvers includes http://repo.typesafe.com/typesafe/releases/.

Play 2.3 JSON with SBT >= 0.13.5
put into build.sbt:
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.3.4"
Play 2.1
build.sbt:
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
scalaVersion := "2.10.2"
libraryDependencies += "play" % "play_2.10" % "2.1.0"
Play JSON is in Play 2.1 not an independent artifact.

Play 2.2 is out and can be added separately from rest of Play Framework. in build.sbt:
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.2.1"

This worked for me (scala 2.11)
resolvers += "Typesafe Repo" at "http://repo.typesafe.com/typesafe/releases/"
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.3.0"

You can use the following to get the Play JSON library:
addSbtPlugin("play" % "play-json" % "2.2-SNAPSHOT")
You may also have to include the following resolver:
"Mandubian repository snapshots" at "https://github.com/mandubian/mandubian-mvn/raw/master/snapshots/"
Here's where I originally got the info: http://mandubian.com/2013/02/21/play-json-stand-alone/

One could check the Getting Started section of the GitHub repository and add the following to the build.sbt file:
libraryDependencies += "com.typesafe.play" %% "play-json" % "2.6.0-M1"
