your dub.json is invalid. Please see 
http://code.dlang.org/package-format

I'm not sure what the exact requirements are for a minimal 
dub.json, but you should at very least have a name. Also, watch 
out for where your source files are: dub expects them in a 
source/ or src/ folder by default, you can change this by setting 
sourcePaths in your dub.json
