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

Place libraryDependencies += "org.scalatest" %% "scalatest" % "1.8" % "test" into build.sbt, not project/build.sbt.
