相信很多人也遇到过这样的问题，测试人员认为每次更新包包含的文件越多，项目的风险的就越大，因此每次都让我们开发打每轮修改后更新包。以前都是靠手工整理这些修改的文件，然后合包！不过这样真的费时费力。后来通过在网上搜索和自己整理，最后终于成功实现了脚本，可以自动打更新包。每次只需要设置上次打包的时间和当前时间就可以了。脚本如下：
<project basedir="." default="usage" name="xiangmu">
<target name="init">
<property name="Name" value="xiangmu" />
<property name="name" value="lingfan" />
<property name="version" value="1.7.0.0" />

<echo message="----------- ${Name} ${version} [${year}] ------------" />
<property name="debug" value="on" />
<property name="optimize" value="on" />
<property name="deprecation" value="on" />
<!--上次打包日期-->
<property name="modifyDate" value="2013-05-06"/>
<!--打包日期-->
<property name="Today" value="2013_05_13"/>
