coffeescript --output not working correctly? Follow

Hello,

I use coffescript and I will compile my coffee's file into another directory with File Watcher.I was thinking to do like this :

I create a new File Watcher CoffeeScript :

it's no working. :(

But if I do :

it's Work! :)


In the documentation : "In the Output Paths text box, specify the files to store the results of running the File Watcher: the resulting source code, source maps, and dependencies. The location is specified relative to the working directory."

I don't understand why Output Paths text box doesn't work for the first screen. Could you help me please? ?:|

Thanks!

Marc
