Three open-source zero-cost Scala IDE's is better than two :-)

Superb news. I've been a fan of IDEA since the first release, you've
always been one step ahead of the competition. Open sourcing the product
can only help accelerate the progress.

Excellent news!!!

FWIW, the moment I discovered IDEA, there was no other choice for me as far as Java development is concerned. This IDE is truly made for productivity. I have also been doing my Scala coding there almost exclusively lately. 

With all three IDE platforms now open-source, power is unleashed.

agreed.

I was able to create a new Scala project with a main method
and run it as an Application - don't use Scala console; that
just brings up the Scala REPL.

I was not able to import an existing Scala project into IDEA
and get it to work. It found my source and detected a Scala
facet and I can edit Scala files with syntax highlighting, etc.
but the entire Scala library was unknown

  Cannot resolve symbol List
  Cannot resolve symbol Array

and so on. When I try to compile/make/rebuild my project I get

Information: 1 error
Error: Internal error (Plugin: org.intellij.scala): null

(see tb below)

This is a Maven project; the Project Structure appear to list the
scala-library.jar:2.7.6-final dependencies, but it just cannot resolve
any symbols. I also tried to add scala-library.jar explicitly
and the plugin just does not seem to find it. I'm new to IDEA,
so I don't know if I'm performing the right steps.

I got this to work; it require several changes. Rather than use the
Project Structure > Modules > Dependencies:

1) In the Project Structure, select Libraries in the left panel and add a new library
   IDEA does not seem to allow adding just a jar, so I used Attach Jar Directories
   and selected my Scala lib c:\dev\scala\current\lib

2) in the Project Structure Facets , select Scala and change
   the Scala compiler and SDK library paths to my installed Scala
   I probably would not need this if step 1 used the scala-library.jar
   from the IDEA Scala plugin, but I want to use a specific version
   of Scala.

3) in Project Structure > Modules, I selected my module and in Sources
   added my Scala source subdirectory. I use Source\Java for Java source,
   Source\Scala for Scala source.

I was then able to rebuild my project (no compile errors; it took a while;
75 .scala files, 700+ classes) and run it as an Application, using my module's
classpath.
