這是一個簡單的幫助文檔，看完后你將學會polish的基本用法，并用它構建你的j2me工程。

      Polish擁有著強大的預編譯命令，用它可以很方便的去打包資源和分離代碼。

1.配置：
第一步解壓縮最好放到根目錄下，無需安裝。
第二步將xml的解析文件copy到工程目錄下。
第三步在xml上單擊右鍵選擇-打開方式-ant構建。
就是這么簡單。

2.介紹xml
下面是一個例子，在這個xml下填寫jad,和資源的目錄。很簡單，相信大家都能看懂。
<!-- This file controls the build process.                    -->
<!-- The most important target is the j2mepolish-target,      -->
<!-- which controls for what devices the application should   -->
<!-- be created and so on.                                    -->
<!--                                                          -->
<!-- Important: when you have no Wireless Toolkit installed   -->
<!-- you need to define the "preverify"-attribute             -->
<!-- of the <build>-element of the J2ME Polish task.          -->
<!--                                                          -->
<!-- When you call Ant from the command-line, you can         -->
<!-- call "ant test j2mepolish" to skip the obfuscation       -->
<!-- and to build the example for fewer handsets.             -->
<!-- The default target builds and obfuscates the example.    -->

3.Polish語法簡介：
幾個例子，
關于不同屏幕大小設置變量坐標。
    //#if (polish.ScreenWidth == 240)
    byteoffextX=20;
    inttitleNameX=25+offextX;
    inttitleNameY=43+20;
    intnameOffestX=33+4;
    intnameOffestY=33;
    intnumOffestX=23;
    intnumOffestY=42+4;
    intnumAllY=-5;

    bytenameTranY=1;

    intmidleMuX=-20+offextX;
    intmidleMuY=-40+30+10;

    intyoungManX=-70+offextX;
    intyoungManY=-40+90+10;

    integgX=-20;
    integgY=-37+90+10;

    intbigEggX;
    intbigEggY=13-12;

    //#else (polish.ScreenHeight == 220)
    //# int titleNameX=25;
    //#     int titleNameY=43;
    //#     byte nameOffestX=33;
    //#     byte nameOffestY=33;
    //#     byte numOffestX=23;
    //#     byte numOffestY=42;
    //#     byte numAllY=-5;

    //#     byte nameTranY=1;

    //#     int midleMuX=-20;
    //#     int midleMuY=-40;

    //#     int youngManX=-70;
    //#     int youngManY=-40;

    //#     int eggX=-20;
    //#     int eggY=-37;

    //# int bigEggX;
    //# int bigEggY=13;
    //#endif

不同按鍵。
    //#if (polish.Vendor == Sony-Ericsson) || (polish.Vendor == Samsung) || (polish.Vendor == Nokia)

     finalstaticpublicintisLeftKey=-6;
    finalstaticpublicintisRightKey=-7;

    //#elif (polish.Vendor == Motorola)
    //# final static public int isLeftKey=-21;
    //# final static public int isRightKey=-22;
    //#endif

    

4. build失敗的可能原因：
Jdk的版本1.42的可以，高版本的會出錯。（可能和polish的版本有關）
Xml的修改的參數有誤，如midlet的名字，是否存在的資源文件夾，wtk,polish的路徑。
Polish語法有錯，這個一般會在build失敗的控制臺下有標記。
另外混淆包的路徑也要設置正確
