scala ide（eclipse）和sbt项目

我正在使用最新版本的 scala ide eclipsehttp://scala-ide.org/

Scala IDE build of Eclipse SDK

Build id: 4.0.0-vfinal-20141216-1226-Typesafe

我有一个可以使用 sbt 从终端运行的项目：

    donbeo@donbeo-HP-EliteBook-Folio-9470m:~/Applications/scala_workspace/progfun-quickcheck$ sbt
[info] Loading project definition from /home/donbeo/Applications/scala_workspace/progfun-quickcheck/project/project
[info] Loading project definition from /home/donbeo/Applications/scala_workspace/progfun-quickcheck/project
[info] Set current project to progfun-quickcheck (in build file:/home/donbeo/Applications/scala_workspace/progfun-quickcheck/)

[info] ! Heap.sort1: Falsified after 1 passed tests.
[info] > ARG_0: List("0")
[info] + Heap.minMeld: OK, passed 100 tests.

我试图将该项目导入到 eclipse 中运行：

ickcheck$ sbt
[info] Loading project definition from /home/donbeo/Applications/scala_workspace/progfun-quickcheck/project/project
[info] Loading project definition from /home/donbeo/Applications/scala_workspace/progfun-quickcheck/project
[info] Set current project to progfun-quickcheck (in build file:/home/donbeo/Applications/scala_workspace/progfun-quickcheck/)
> eclipse
[info] About to create Eclipse project files for your project(s).
[info] Successfully created Eclipse project files for project(s):
[info] progfun-quickcheck
>

然后我将项目导入 eclipse。当我尝试从 eclipse 运行该项目时，出现以下错误：

我的理解是，我使用的 ecplise 版本应该有自己的 sbt 插件，所以也许这可以让事情变得更容易。

那么我怎样才能从 eclipse 运行该项目？

这个问题和那个问题不是很相似吗：https://stackoverflow.com/questions/26701992/exception-occurs-when-running-scala-test-from-eclipse? 错误完全相同。

解决方案是：
“检查你的类路径；特别是检查你所依赖的 scalatest 版本是否针对 scala 2.11 而不是 2.10 编译。”——作者 lmm。
