ANT的利用范疇很廣，而且用起來也是簡略方便。最近用ANT工具實現了J2ME程序的編譯，打包，混雜，運行 ，一條龍服務，以後再也不用在IDE裡點來點往，浪費時間了，寫篇文章，做為總結。
一 實現J2ME程序的編譯，打包，混雜，運行 的環境
1） Java環境
開發環境是JDK1.5，WTK22
2） 環境變量
Java_HOME,PATH,WTK_HOME之類的設置
3） JAR包
混雜包：proguard3.5
針對J2ME的包：antenna.jar
二 編寫build.XML
<?XML version="1.0" encoding="UTF-8"?>
<project name="MobileBook" default="run" basedir=".">
<property name="midlet.name" value="MobileBook"/>
<property name="wtk.cldc.version" value="1.0"/>

<target name="clean">
<delete includeEmptyDirs="true" quIEt="true">
<fileset dir="${path.build}" includes="*,*/**"/>
</delete>
</target>
</project>
三 運行
運行命令：ANT -f E:\Ant\Build.XML
有個處所是要留心的，<wtkjad jadfile="${midlet.name}.jad"name="${midlet.name}" vendor="" version="">，假如vendor="" version=""值為空的話，調用手機模仿器的時候會出錯的。
固然結構不是很明白，顯得有點粗糙，也算是告一段落。
