improving scala code compilation time in Intellij IDEA

Question

Iam in the process of learning Scala using IntelliJ IDEA 10.0.x with scala plugin and I have found that compiling scala takes more than 10 secs. I know there is a an option to turn on the fast code compilation (FSC) in scala however Iam unaware of how to configure that in IDEA is there any option available.

Answer 1

After reading "Why does IntelliJ IDEA compile Scala so slowly?", I would rather use IntelliJ IDEA with sbt:

• idea-sbt plugin: for using the SBT Console tool window to enter SBT commands directly.

Note that sbt cannot use fsc either (in interactive mode).

Answer 2

After create a scala project in IDEA go Run/Edit Configurations:

1. Click in +
2. Select Scala Compilation Server, and give a name to this configuration.
3. Now press run.
