SBT.解决play sbt-plugin的依赖关系

我用sbt 0.13.1(myProject/project/build.properties/有sbt.version=0.13.1)

在我的 myProject/project/play.sbt

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

addSbtPlugin("play" % "sbt-plugin" % "2.2.1")

我尝试了很多版本,但无论我做什么,都无法解决这种依赖.我最终得到这样的错误:

[error](*:update)sbt.ResolveException:unresolved dependency:play #sbt-plugin; 2.2.1:not found

我甚至尝试把scalaVersion := "2.9.1"到play.sbt要与仓库相一致(在情况下,如果事情到此并):

/typesafe/releases/play/sbt-plugin/scala_2.9.1/sbt_0.11.3/

但它不起作用.

嗯？
