Play! Framework 2.2.0 Unresolved dependencies

play application 구현 중에 이 error 메시지는 반드시 한 번은 보는 듯.

[warn] ::::::::::::::::::::::::::::::::::::::::::::::

[warn] Note: Some unresolved dependencies have extra attributes.  Check that these dependencies exist with the requested attributes.
[warn] play:sbt-plugin:2.2.0 (sbtVersion=0.12, scalaVersion=2.9.2)
[warn]

sbt.ResolveException: unresolved dependency: play#sbt-plugin;2.2.0: not found
at sbt.IvyActions$.sbt$IvyActions$$resolve(IvyActions.scala:214)

sbt.plugin의 버전과 group, artifact, revision을 변경해 줘야 한다.

From

// Comment to get more information during initialization
logLevel := Level.Warn

// The Typesafe repository
resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

// Use the Play sbt plugin for Play projects
addSbtPlugin("play" % "sbt-plugin" % Option(System.getProperty("play.version")).getOrElse("2.1.0"))

to

// Use the Play sbt plugin for Play projects
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.2.0")

그리고 같은 폴더의 build.properties 파일에서 sbt version도 아래와 같이 변경해야 함.

sbt.version=0.13.0

다시 실행하니 성공
