我怎么能够把Schala的版本改变在一片 s项目中?
我想SBT检查该系统的Schala版本是否正确,如果情况并非如此,那么它就会下载。

scalaVersion := "2.10.1"
You can temporarily switch to another version of Scala using
++<version>.
This version does not have to be listed in yourbuild.scala.versionsproperty, but it does have to be in a repository or be a local Scala version you have defined.
但是,CrossBuild page更适合你想要的东西,因为它在行动上表明如何改变build.scala.versions财产。
因此,你应当能够
set build.scala.versions 2.7.7
reload
set build.scala.versions 2.8.0.RC2
reload
并且每次都生成一个有不同统计版本的汇编。
