grunt配置-copy任务

copy任务配置项使用示例：

copy: {
  main: {
    files: [
      // includes files within path 
      {expand: true, src: ['path/*'], dest: 'dest/', filter: 'isFile'},
 
      // includes files within path and its sub-directories 
      {expand: true, src: ['path/**'], dest: 'dest/'},
 
      // makes all src relative to cwd 
      {expand: true, cwd: 'path/', src: ['**'], dest: 'dest/'},
 
      // flattens results to a single level 
      {expand: true, flatten: true, src: ['path/**'], dest: 'dest/', filter: 'isFile'},
    ],
  },
},

flatten:设置（true、false）用来指定是否保持文件目录结构

那么配置为如下任务

copy: {
    dev : {
                files : [{
                    expand : true,
                    cwd : 'app',//根目录
                    dest : 'test123',
                    src : '*.html'//基于cwd的子目录
                }]
            }
}

执行 grunt copy:dev就将app目录下所有的html文件都复制到app/test123目录下
