sbt: Add dependency on scalatest library. Where?

Question

I created a scala project using SBT and wrote some unit test cases using scalatest. But somehow sbt test can't find the org.scalatest package.

Here my project definition files:

• Sources are in src/main/scala respective src/test/scala

• build.sbt :

   name := "MyProject" version := "0.1" scalaVersion := "2.9.2" 

• project/plugins.sbt :

   addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.1.0") 

• project/build.sbt :

   libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test" 

I'm using SBT 0.11.3.

Compiling the program using sbt compile on the console works fine. Furthermore I found the scalatest jar in ~/.ivy2 , so SBT must have downloaded it.

But when running sbt test , it says

object scalatest is not a member of package org
[error] import org.scalatest.FlatSpec
...[many errors alike]

And running sbt eclipse creates a .classpath that doesn't contain the scalatest jar.

Do I have to specify the test dependencies somewhere else? How should I add the scalatest library?

Answer 1

将libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test"放入build.sbt ，而不是project / build.sbt 。
