'Invisible' errors while compiling Haxe

I have spent so much time trying to get Intellij IDEA 14.0.2 to work with Haxe, without much success.

Every time I compile, I get two 'invisible' errors (see image). They seem to show up at the very start of the compilation process and persist until the end. My application will not run from the IDE. If I go and manually run the application, it opens up fine.
