上一篇文章，我们大致讲了polish的一个基本应用，但我们手头上有同一个游戏不同版本的代码的时候，我们就开始利用polish进行整合，那么在利用polish之前，我们必须把环境搭配好，接下来简单的谈谈polish环境的搭建。 1、eclipse me+jdk+wtk这是开发环境，一般移动百宝箱需要我们用wtk1.0.4，而一般我们开发可以用更高的版本wtk2.2. 2、ant工具（ant是一个基于JAVA的自动化脚本引擎，脚本格式为XML。除了做JAVA编译相关任务外，ANT还可以通过插件实现很多应用的调用。） 3、polish安装文件 4、build.xml文件 对于第一条，我想这样的文章已经很多了，我就不说了。关于ant工具，大家可以去下ant的免安装包，解压缩路径假如是E:/ant/，那么把E:/ant/bin;添加到系统环境变量中的path中就可以了。这个时候你打开cmd，敲入ant后如果提示：Warning: JAVA_HOME environment variable is not set. If build fails because sun.* classes could not be found you will need to set the JAVA_HOME environment variable to the installation directory of java.
Buildfile: build.xml does not exist! Build failed则说明安装成功，警告没有可供解析的build.xml文件，这个工具到底用来干嘛的，等我们最后分析完build.xml的时候，大家就知道了。 polish的下载安装也很简单，大家可以搜索一下，安装就可以了，笔者的安装路径是E:/JAVA/J2ME-Polish。 接下来就是定制自己的build.xml了。笔记给出一个简单例子，并简单给出解释，希望对大家有所帮助： <project name="KalaPolish" ------------------------------------------>你的项目名称 default="j2mepolish"> <property file="${user.name}.properties" /> <property name="polish.home" location="E:/JAVA/J2ME-Polish" />--------------------------->你的polish安装路径 <property name="wtk.home" location="E:/JAVA/WTK22" />--------------------------->你的wtk安装路径 <property file="${polish.home}/global.properties" /> <!-- Definition of the J2ME Polish task:--> <taskdef name="j2mepolish" classname="de.enough.polish.ant.PolishTask" classpath="${polish.home}/import/enough-j2mepolish-build.jar:${polish.home}/import/jdom.jar:${polish.home}/import/proguard.jar:${polish.home}/yguard-lib.jar:${wtk.home}/wtklib/kenv.zip"/>

以上红色比分，大家修改成自己的就可以了，当然，玩家也可以把打包工具改成wtk1.0.4，注意的是，无论你的打包工具，bin目录下面是否安放了混淆器，都没有关系，因为打包用的混淆器并不是利用wtk里面的混淆器，而是利用了，polish自带的混淆器，具体polish怎么解析这个build文档，大家可以看polish的原文件。有点提醒大家，混淆器的定义的时候，本文中是ProGuard，第一个字母必须大写，否则就出错，想知道问什么的，可以去看polish的代码实现中关于混淆器的代码。 好了，把这个文档放到你的项目目录下面，就可以在eclipse中点击这个build.xml选择ant构建来打包我们的程序了。到这里我们的环境就配置好了。文章写的很粗略，希望对大家有所帮助。文章红色部分为注释，用的时候，必须删除。
