"grunt watch" gets an error: "Warning: Unable to write "undefined" file (Error code: undefined). Use --force to continue."
Therefore "this.data.dest" is undefined in an "grunt watch", use this.files instead.
"grunt build" is successful without errors.
Example configuration for this problem

@christian-beckmann sorry for the delay here :S I've merged in the oldest PR, will that fix the current issue? |

Hopefully it run's (did'nt test it). But at least I didn't have the project anymore. |

With grunt build everything worked fine. But when I used grunt watch I get the error "Warning: Unable to write "undefined" file (Error code: undefined). Use --force to continue."
Because this.data.dest was not defined in this context. this.data.files alias this.files has the right destination filename. Inspired by grunt-contrib-coffee I wrote this bugfix and it "grunt watch" worked now correctly.
