PredictionIO IntelliJ setup. Missing module SDK

Question

I'm trying to setup IntelliJ Idea for PredictionIO engine development in Scala. I'm following the documentation step by step. However, I am unable to build the project due to missing SDK.

enter image description here

I have JDK installed. Should I point to this SDK there? Thanks for help!

I installed Scala Plugin for IntelliJ. The SDKs dropdown is empty. — Rafał Sroka, Jul 13 '15 at 13:52
Did you try right-click on the project > Add Framework Support? Did you install Scala and Java on your system? — eliasah, Jul 13 '15 at 14:02
I installed Java. I didn't install Scala, just the Scala plugin for IntelliJ. When I go to `Add Framework Support` I see to options there `Maven` and `Groovy`. — Rafał Sroka, Jul 13 '15 at 14:17

I think it is because the SDK of Scala is missing. Installing the plugin of Scala in IntelliJ is not enough. There are two ways to solve this:

Install Scala in your computer and fill the right path of Scala in the field of SDK of Scala in IntelliJ.
Use IntelliJ to download the SDK of Scala. You can find the download button in the “project settings”.

Please comment if you need more clarification.
