Printout of my coffee task in gruntfile.coffee is

coffee:
  compile:
    files:
      "./*.js": ["./*.coffee"]
      './config/*.js': ['./config/*.coffee']
      './rest/*.js': ['./rest/*.coffee']

      './spec/*.js': ['./spec/*.coffee']

If you are using grunt@0.4.0rc7, then you need to install grunt-contrib-coffee@0.4.0rc7. The grunt API for grunt.file.expand has changed with b60907b

The experimental support for wildcard destinations has been removed. Please see "building the files object dynamically" @ http://github.com/gruntjs/grunt/wiki/Configuring-tasks for the new method (which works with any task).
