Thanks @javadba and @chenrui333

@chenrui333
Thank you !!!...
This is much easier than change system variable manually :)

Thanks! After installing this way though, I get duplicate sources.list entries... is anyone else getting that when doing an sudo apt-get update?

Thanks for idea.

I've made some changes to this script for using java7 dependency instead of java6: https://gist.github.com/maizy/c4d31c1f539694f721f6
It may be useful for someone.

Hey, you've already installed scala and sbt using the deb packages, why do you follow that with "apt-get install" of these packages?

scala: scala-2.11.6.deb
sbt: sbt-0.13.8.deb
