Can't configure Scala in Intellij IDEA 13

I entered Scala courses on Coursera and used to write Scala projects in Eclipse Indigo. All worked well. But now I gonna to convert to my favorite IDE - Intellij IDEA.

But I can't configure it for Scala usage.

What I've already done:

  1. Install Scala, set system SCALA_HOME variable
  2. Install SBT
  3. Install Scala plugin on Intellij IDEA

What a problem:

  1. When I import coursera assignments, Intellij doesn't see some classes like List, Array etc. For example, when I try to import it via Alt+Enter key it propose me java.jang.reflect.Array, java.sql.Array, com.sun.xml....Array. So I can't import Scala Array with tail and head methods.

  2. When I try: New Project -> Scala Module the are to problems:

    a) When I choose Set Scala Home it complains that there are missing files

    b) When I choose Existent Library there is nothing to choose in Compiler/Standart fields.

enter image description here

Question:

How to configure Intellij properly?

It can be a problem with caches, try File -> Invalidate Caches

Make sure to manually add the scala-library as a dependency to your module. This is not done automatically when adding the Scala facet to an existing module.

Is the directory you specified the right one? It should have bin, doc, etc. in it. If so, try entering the following by hand:

For compiler library, scala-compiler

For standard library, scala-library

IDEA found these for me automatically, but perhaps something went wrong for you.
