SBT没有正确应用build.sbt

Question

我想建立Akka项目。

所以，我在项目的根文件夹中创建了 build.sbt文件，如下所示：

name := "Akka Sample"

version := "1.0"

scalaVersion := "2.10.1"

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

libraryDependencies += "com.typesafe.akka" %% "akka-actor" % "2.2-SNAPSHOT"

并在控制台行上键入此内容。

结果是

C:\scala\work\AkkaSample>sbt update

C:\scala\work\AkkaSample>set SCRIPT_DIR=C:\sbt\

C:\scala\work\AkkaSample>java -Xmx512M -jar "C:\sbt\sbt-launch.jar" update
[info] Building project AkkaSamples 1.0 against Scala 2.9.0

您可能会注意到我将scalaVersion设置为2.10.1，但是sbt已经建立了Sacla 2.9.0

似乎sbt工具无法正常工作。

我试图找到一个解决方案，但由于我不是母语为英语且我不熟悉英语，所以我找不到解决方案......

请让我抓住解决方案，谢谢。

度过美好的一天！
