egret项目，通过gulp，根据输入资源类型，按文件夹名称作为group名称，自动生成xxx.res.json文件

 

gulpfile.js

var gulp = require('gulp'); 
var fs = require("fs");

//type 角色0，动画1
var type=1;

		case 0:
			resPath="../resource/Arts/Animals/xxxA/";
			dirPath="Arts/Animals/xxxA";
			resName="xxxA.res";
		break;
		//骰子
		case 1:
			resPath="../resource/Arts/Animals/xxxB/";
			dirPath="Arts/Animals/xxxB";
			resName="xxxB.res";
		break;
	}
}
