How to use properly Sublime Text 3 for snowkit-based development?

sign up sign in

I've tried to use Sublime Text 3 with flow plugin by Sven and haxe plugin by clemos and but have no proper completion and Goto Definition(Haxe) always unable to find classes. Then I've added luxe and snow folders to sublime project And copied build.hxml created by flow in bin/ but none of that helped.
Maybe I'm missing something or do not know any details?
I'me new to haxe and snowkit.
Thank in advance.
