使用YUI+Ant 實現(xiàn)JS CSS壓縮

更新時間：2014年09月02日 17:46:35 投稿：hebedich

YUI庫是一組工具和控件，它們用JavaScript寫成, 為的是用DOM 腳本,DHTML和AJAX等技術(shù)創(chuàng)建豐富的網(wǎng)頁交互式應(yīng)用程序。YUI 基于BSD協(xié)議，對所有的使用方式都是免費的。YUI 項目包括YUI 庫和兩個創(chuàng)建時工具：YUI Compressor (壓縮)和YUI Doc（JavaScripts代碼的文檔引擎）

今天研究了一下YUI yahoo開源框架，感覺很猛啊。

于是乎我做了一個YUI的ant實現(xiàn)，網(wǎng)上好多關(guān)于bat的實現(xiàn)，我就另辟蹊徑，出個關(guān)于這個的ant實現(xiàn)，嘿嘿獨一無二的文章，如果轉(zhuǎn)載的話，其注明作者和網(wǎng)站

好了具體操作如下：

具體的相關(guān)代碼如下：

#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
