Grunt usemin在生成时不移动javascript依赖项

我用约曼搭建了我的申请，并使用了

问题是当我有main.js文件时，当我运行

build

任务时，它不会复制

grunt build

我似乎不知道Gruntfile出了什么问题

'use strict';

module.exports = function (grunt) {

  // Time how long tasks take. Can help when optimizing build times
  require('time-grunt')(grunt);

  require('load-grunt-tasks')(grunt);

    app: 'app',

  // Define the configuration for all the tasks
