I'm having a hard time configuring this. I have installed the File Watcher plugin from the repository and tried compiling a LESS file. It gave me an error because it did not include the LESS compiler with that download.
So I downloaded this compiler and extracted it: https://github.com/duncansmart/less.js-windows
I then went to the LESS File Watcher settings and inputted "C:\LESS\lessc.cmd" under the Program field. I then made some changes to a LESS file and got the following error:
lessc.wsf: no input files
