After adding
添加后
libraryDependencies += "org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
to build.sbt, and refreshed the project, I got this msg.
到build.sbt，并刷新项目，我得到了这个味精。
[warn] Multiple dependencies with the same organization/name but different versions. To avoid conflict, pick one version:
[warn] * org.scala-lang:scala-reflect:(2.11.2, 2.11.7)
[warn] * org.scala-lang.modules:scala-xml_2.11:(1.0.2, 1.0.4)
[警告] 具有相同组织/名称但版本不同的多个依赖项。为避免冲突，请选择一个版本：
[警告] * org.scala-lang:scala-reflect:(2.11.2, 2.11.7)
[警告] * org.scala-lang.modules:scala-xml_2.11:(1.0.2, 1.0.4)
And in build.sbt, thw word 'scalatest' is red that means it's an unsolved dependencies.
在build.sbt 中，' scalatest'这个词是红色的，这意味着它是一个未解决的依赖项。
Should I change something in Project Setting, like scala sdk?
我应该在项目设置中更改某些内容，例如 scala sdk？
Best Regard!
最良好的问候！

You could regard adding those dependencies:
您可以考虑添加这些依赖项：
libraryDependencies ++= Seq(
"org.scala-lang" % "scala-reflect" % "2.11.7",
"org.scala-lang.modules" % "scala-xml_2.11" % "1.0.4"
)
It forces compiler to choose concrete version of libraries. It solves problem for me.
它强制编译器选择库的具体版本。它为我解决了问题。

I was able to resolve this by excluding these from the scalatestdependency.
我能够通过从scalatest依赖项中排除这些来解决这个问题。
libraryDependencies ++= Seq(
"org.scalatest" % "scalatest_2.11" % "2.2.4" % "test"
exclude("org.scala-lang", "scala-reflect")
exclude("org.scala-lang.modules", "scala-xml_2.11")
)
