For when something goes horribly wrong.
See the fail lib source for more information.
If something explodes (or is about to explode) inside a task, it can force Grunt to abort. See the exit codes documentation for a list of all built-in Grunt exit codes.
Note that any method marked with a ☃ (unicode snowman) is also available directly on the grunt object. Just so you know. See the API main page for more usage information.
Display a warning and abort Grunt immediately. Grunt will continue processing tasks if the --force command-line option was specified. The error argument can be a string message or an error object.
grunt.fail.warn(error [, errorcode])If --stack is specified on the command-line and an error object was specified, a stack trace will be logged.
This method is also available as grunt.warn.
Display a warning and abort Grunt immediately. The error argument can be a string message or an error object.

A beep is emitted on fatal unless the --no-color option is specified.
This method is also available as grunt.fatal.
