项目采用maven构建的时候，须要压缩js，css等，网上找了相关资料，本身综合了下～ 

直接放代码： 

css

更喜欢采用谷歌的closure-compiler + maven-antrun-plugin

JQUERY 的压缩工具 uglifyjs版本的配置，必需要有nodejs环境 （executable="node"）即在cmd中可以执行 node --version. uglifyjs能够在https://github.com/mishoo/UglifyJS 下载，下载后续稍稍修改bin/uglifyjs，把里面的 
Js代码   收藏代码
  1. var uglify = require("uglify-js")  


修改成 
Js代码   收藏代码
  1. var uglify = require("./uglify-js");//或者 ../uglify-js  

由于uglify-js默认是在bin目录外面的。 

如需更新uglify的版本，每次覆盖相应文件，只修改上面文件便可。
