JDK 1.8 - can't with import sbt project

Question

I have some trouble after installing java 1.8 on Ubuntu Gnome 14.04 with Intellij Idea 13.1.

When I tried to import sbt project it throws next:

I tried to install and set up java 1.7 at .pam-environment. But it keep taking 1.8 as main configuration and throwing this warning. I solved it by completely delete 1.8 version.

Version of scala:

nazar@lelyak-desktop:~⟫ scala -version
Scala code runner version 2.10.4 -- Copyright 2002-2013, LAMP/EPFL

And sbt - 0.13.1

I wondering to know how to use sbt with JDK 1.8?

Or with let sbt to use 1.7 version when 1.8 is default.

SOLUTION:

I changed configuration at settings for sbt to custom JDK - 1.7 and sbt-launch.jar - have installed by me.

Answer 1

The reason for the warning/error is that in Java 8 the permanent generation was removed.

You can change settings in IntelliJ idea not to add -XX:MaxPermSize. Go to settings page and click edit next to VM Parameters.

Remove parameter called -XX:MaxPermSize.
