Gruntjs 与grunt contrib concat的接触不'；行不通

我使用grunt contrib concat，但它似乎不起作用。 所有文件都在文件夹中

我使用了

--verbose

查看详细信息，但似乎一切都正常工作

 concat: {
   options: {
    // define a string to put between each file in the concatenated output
    separator: ';'
  },
   dist: {
      // the files to concatenate
      src: [
          //'assets/javascript/components/*.js',
          'assets/javascript/components/jquery-ui-1.10.3.custom.js',
          'assets/javascript/components/spectrum.js',
          'assets/javascript/components/prefixfree.min.js',
         'assets/javascript/src/jquery.menu_css3.js'
      ],
      // the location of the resulting JS file
      dest: 'assets/javascript/jquery.<%= pkg.name %>.min.js'
    }
  },

---

运行任务后，

dest

文件的内容是什么？此文件：jquery.menu\u css3.js到jquery.menu\u css3.min.js。但除此之外，它是用uglyfly压缩的。我把所有文件都放在src中，效果很好。
