title: IntelliJ with Golang throws IllegalArgumentException
body: <p>I am encountering the following Problem:
  When I try to add the Go-SDK to my Project, and select the GOROOT-Path (C:\Lib\Go), I get an <code>IllegalArgumentException</code>.</p>
  
  <p>I googled it, and lots of People are encountering this issue.
  One solution would be the Installation of a later golang-plugin for IntelliJ which is currently in the Alpha, but however when I download the source from github and open it in IntelliJ, I get lots of Errors, so I am unable to build it and create an executble jar-plugin. I think all dependencies should be directly in the Project integrated?!</p>
  
  <p>Do you know other Solutions, or maybe an IDE with similiar Features like IntelliJ.</p>
