Is there a correct environment setting for Intellij in Ubuntu?

Hi all, I asked this here in hopes that someone well-versed in both Intellij and Ubuntu can shed can light on this.

I went through HELL trying to make a java program run on Eclipse/Intellij because of one thing: incorrectly configured environment.

I'm now trying to get a fairly complicated java program to run on Ubuntu Intellij which i already installed fresh, so before i even bother trying to make it run(since my past sad history with IDEs mean its gonna screw with 50 over unidentifiable errors in a correct sourcecode), i need to ask:

IS THERE A CORRECT ENVIRONMENT SETTING for intellij? I've already installed Openjdk 8 on Ubuntu(not sure if Oracle should have been the one to go for tho) 

Thanks in advance for any help =)
