Why does console in IDEA 10 fail with "tools is not a member of package scala"?

Question

I have latest IntelliJ installed (10.0.1) with the Scala plugin.

Whenever I run something in a console, I get an error.
Here is an example (I tried to load some scala file)

"C:\Program Files\Java\jdk1.6.0_05\bin\java"
-Didea.launcher.port=7533 "-Didea.launcher.bin.path=C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 10.0.1\bin"
-Dfile.encoding=UTF-8 
-classpath "C:\`development\scala\lib\scala-compiler.jar;C:\`development\scalalib\scala-library.jar;C:\Documents and Settings\alex.repede\.IntelliJIdea10\config\plugins\Scala\lib\scala-plugin-runners.jar;C:\Program Files\JetBrains\IntelliJ IDEA Community Edition 10.0.1\lib\idea_rt.jar" 
com.intellij.rt.execution.application.AppMain    

Through:

org.jetbrains.plugins.scala.compiler.rt.ConsoleRunner
-classpath "C:/Program Files/Java/jdk1.6.0_05/jre/lib/ext/localedata.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/management-agent.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/plugin.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/resources.jar;C:/`development/scala/lib/scala-swing.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/ext/sunmscapi.jar;

C:/Program Files/Java/jdk1.6.0_05/jre/lib/ext/sunpkcs11.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/javaws.jar;
C:/Program Files/Java/jdk1.6.0_05/jre/lib/jce.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/rt.jar;C:/Program Files/Java/jdk1.6.0_05/jre/lib/ext/sunjce_provider.jar;
C:/Program Files/Java/jdk1.6.0_05/jre/lib/charsets.jar;"

gives:

What's wrong with this console ?

Here is another example :

scala> val x = 5
x: Int = 5
<script>:3: error: value tools is not a member of package scala
  var value: scala.tools.nsc.InterpreterSettings = _
                   ^
<script>:4: error: value tools is not a member of package scala
  def set(x: Any) = value = x.asInstanceOf[scala.tools.nsc.InterpreterSettings]
                                                 ^

Answer 1

Add the scala-compiler.jar (or scala-compiler-2.x.y global library) to your module's dependencies

Answer 2

Add -usejavacp to your console arguments (in run -> edit configurations).

Answer 3

For IntelliJ 12.1.4. Right click on project -> select "Add Framework Support..." -> Select Scala

When Scala is not is not available, install plugin Settings -> Plugins -> Install JetBrains Plugin ... -> search for Scala
