How to setup Intellij for Scala 2.10

Question

• First I installed macports

• Then I installed Scala and Play through macports: To make sure installation works I run a "hello world" on eclipse. It works!

• But since my objective is to use Intellij, I try to follow the instructions at http://confluence.jetbrains.com/display/SCA/Getting+Started+with+IntelliJ+IDEA+Scala+Plugin

• On step 3 of the instructions (section Creating a Project), under use scala distribution, I am not sure what to type. Will someone please tell me what to type? I am using mac os x mountain lion. I don't know the path to my scala installation.

I appreciate the help. I have already looked at Intellij Idea setup for Scala, clarification needed. No help there. My Intellij version is 12.0.3 and my scala install is 2.10.

Answer 1

Just for clarification: you can install scala in Mac OS X using Homebrew as @JasonG mentions:

$ brew install scala --with-docs

In that case, the selected solution won't work, as IntelliJ will still complain. Any way, as stated in the caveats of the formula, you will have a directory specially crafted for IntelliJ integration:

==> Caveats To use with IntelliJ, set the Scala home to: /usr/local/opt/scala/idea

Using this directory will make IntelliJ happy.

UPDATE for IntelliJ IDEA 13.x users: This doesn't seem to be needed any more. Just use SBT based projects, and everything will be downloaded and configured automatically (Scala compiler and libraries)

Answer 2

You're much better served by letting existing tools do this sort of thing for you.

Define your project using SBT. Use PaulP's (Paul Phillips) SBT launcher and the sbt-idea plug-in that provides automatic generation of IDEA project and module files.
