使用YUI+Ant 实现JS CSS压缩

今天研究了一下YUI yahoo开源框架，感觉很猛啊。

于是乎我做了一个YUI的ant实现，网上好多关于bat的实现，我就另辟蹊径，出个关于这个的ant实现，嘿嘿独一无二的文章，如果转载的话，其注明作者和网站

好了具体操作如下：

官网:

yuicompressor-2.4.6.jar 下载地址 http://yuilibrary.com/downloads/#yuicompressor

YUIAnt.jar 下载地址 http://www.ubik-ingenierie.com/miscellanous/YUIAnt/

具体的相关代码如下：

#css work dir
commonCss.dir = css 

#js work dir
commonJs.dir = js 

#build temp dir
output.temp.dir = build 

#output files in the directory
output.dir = ${output.temp.dir}_output 

#environment needs lib
liblib = lib
