Adding Play JSON Library to sbt

Question

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/.

Accepted Answer

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.
