 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。
