Why does IntelliJ install Scala SDK in /home/<user/.ivy2/cache/?

  • 772

I have installed IntelliJ and the Scala SDK using the installation wizard provided by IntelliJ. I selected the latest version 2.11.8 but were not able to run it in the terminal.

After that I ran 

sudo apt-get install scala

and now which is apparently version 2.9.2

scala -version
Scala code runner version 2.9.2 -- Copyright 2002-2011, LAMP/EPFL

My question is how I can manage to have only one version of scala which is used by IntelliJ and all other users on my system.

  1. IntelliJ doesn't ever, and won't ever, have system level write access to make that. For the most part, it only touches files in your home directory, or in other system directories you tell it to open files from.

    Install scala through the package manager, and then configure IntelliJ to use that instead. Since IntelliJ doesn't have system wide privileges you don't have the ability to have it install and manage scala systemwide; this unfortunately leaves you with 2.9.2.

    Your only other option for updating/upgrading scala would be to find a PPA that has the latest version, but that may introduce other breakages.\
