title: Compass can't find any sass files to compile after running grunt
body: <p>I'm trying to run <code>compass</code> to compile my <code>.scss</code> files.  I'm getting the following error:</p>
  
  <pre><code>Running "compass:dist" (compass) task
  Compass can't find any Sass files to compile.
  Is your compass configuration correct?.
  If you're trying to start a new project, you have left off the directory argument.
  Run "compass -h" to get help.
  
  Running "watch" task
  Waiting...
  </code></pre>
  
  <p>My <code>.scss</code> files are stored in <code>/myproject/sass/</code> and <code>/myproject/sass/bootstrap/</code></p>
  
  <p>I'm expecting the <code>.scss</code> files to be compiled into a minified <code>style.css</code> file.</p>
  
  <p>What do I need to do to sort this?</p>
  
  <pre><code>        compass: {
              dist: {
                  options: {
                      sassDir: 'sass',
                      cssDir: 'css'
                  }
              }
          },
  
          watch: {
              css: {
                  files: '**/*.scss',
                  tasks: ['compass']
              }
          }
      });
      grunt.loadNpmTasks('grunt-contrib-compass');
      grunt.loadNpmTasks('grunt-contrib-watch');
      grunt.loadNpmTasks('grunt-minified');
      grunt.loadNpmTasks('grunt-contrib-concat');
      grunt.loadNpmTasks('grunt-contrib-cssmin');
      grunt.loadNpmTasks('grunt-contrib-uglify');
      grunt.registerTask('default',['concat', 'minified', 'uglify', 'compass', 'watch']);
  </code></pre>
  
  <p>This might be worth trying:</p>
  
  <pre><code>watch: {
    sass: {
      files: '/sass/**/*.scss',
      tasks: ['default']
    },
  },
  </code></pre>
