未找到scalacheck / scalatest：如何在sbt / scala中添加它？

我已经在我的ubuntu12上安装了 http://typesafe.com/stack/download的typesafe-stack,而不是我创建了一个play项目(g8 typesafehub / play-scala),现在我想在我的项目中添加scalatest或scalacheck.

所以my_app / project / plugins.sbt有以下几行：

// 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" % "2.0.1")

然后我使用addSbtPlugin添加了scalatest：

addSbtPlugin("org.scalatest" %% "scalatest" % "2.0.M1" % "test")

现在,当我运行’sbt test’时,它会失败并显示以下消息

[info] Resolving org.scalatest#scalatest;2.0.M1 ...

我不明白：为什么它使用这个http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom URL而不是真正的http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1/2.0.M1/scalatest_2.9.1-2.0.M1.pom？

与scalacheck相同的问题：它还尝试使用特定于sbt-version的artifactId进行下载,而存储库仅具有特定于scala的版本.

我究竟做错了什么？我知道sbt中必须有一个开关,而不是使用sbt-version作为工件URL的一部分？

我也尝试在我的plugins.sbt中使用它

libraryDependencies += "org.scalatest" %% "scalatest" % "2.0.M1" % "test"

但看起来它被sbt完全忽略,scalatest.jar没有出现在类路径中：

my_app/test/AppTest.scala:1: object scalatest is not a member of package org
[error] import org.scalatest.FunSuite

因为sbt clean&&的输出sbt测试有很多
????解决org.easytesting#fest-util; 1.1.6或只是另一个库,但没有关于scalatest.

我使用scala 2.9.1和sbt 0.11.3,试图使用scalatest 2.0.M1和1.8; scalacheck：

resolvers ++= Seq(
  "snapshots" at "http://oss.sonatype.org/content/repositories/snapshots","releases"  at "http://oss.sonatype.org/content/repositories/releases"
)

libraryDependencies ++= Seq(
  "org.scalacheck" %% "scalacheck" % "1.9" % "test"
)

使用相同的结果,即它使用不存在的sbtVersion特定POM URL.

我究竟做错了什么？谢谢.

libraryDependencies += "org.scalatest" %% "scalatest" % "2.0.M1" % "test"
