title: IntelliJ Idea, run code regardless of errors in unrelated project files
body: <p>One thing that I miss from Eclipse is that I can't run code for testing various things (think short main()) if some totally unrelated files in my project contain errors. I've read in FAQ that I can use Eclipse compiler with -proceedOnErrors argument but it still doesn't work. Temporarily fixing unfinished code to compile is not really what I want.</p>
  
  <p>I should note that I use Scala plugin too but still majority of my code are Java files.</p>
