ANT的应用范围很广，而且用起来也是简单方便。最近用ANT工具实现了J2ME程序的编译，打包，混淆，运行 ，一条龙服务，以后再也不用在IDE里点来点去，浪费时间了，写篇文章，做为总结。
一 实现J2ME程序的编译，打包，混淆，运行 的环境
1） JAVA环境
开发环境是JDK1.5，WTK22
2） 环境变量
JAVA_HOME,PATH,WTK_HOME之类的设置
3） JAR包
混淆包：proguard3.5
针对J2ME的包：antenna.jar
二 编写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"/>
<property name="wtk.midp.version" value="2.0"/>
<!—->
<property name="path.antenna.jar" value="E:\work\Java\ant-1.7.0\lib\antenna.jar"/>
<property name="wtk.home" value="D:\WTK22"/>
<property name="wtk.proguard.home" value="E:\work\Java\proguard3.5"/>
<property name="path.build.output" value="${basedir}/Deploy"/>
<property name="flag.autoversion" value="false"/>
<property name="project.root" value="${basedir}"/>
<property name="path.build.output" value=" ${basedir}/build"/>
<property

value="${wtk.home}\lib\midpapi20.jar;${wtk.home}\lib\cldcapi11.jar;

<property name="path.build" value="${basedir}/build"/>
<property name="path.build.classes" value="${basedir}/build/classes"/>
<property name="flag.preverify" value="true"/>
<property name="run.device.name" value="DefaultColorPhone"/>
<property name="run.trace.options" value=""/>
<property name="jad.vendor" value="1.0"/>

<path id="classpath.project">

<path location="${path.build.classes}/_no_export"/>
<path location="${project.root}/KXml.jar"/>
</path>
<target depends="initialize_antenna" name="jad">
<wtkjad jadfile="${midlet.name}.jad" name="${midlet.name}" vendor="${jad.vendor}" version="${jad.version}">
<!–要修改，class是指向你工程的入口类–>
<midlet name="${midlet.name}" icon="" class="com.gaodu.book.AppMidlet"/>
<attribute name="MIDlet-Jar-URL" value="${midlet.name}.jar"/>

</wtkbuild>
<wtkbuild destdir="${path.build.classes}" encoding="GBK" source="1.3" sourcepath="" srcdir="${project.root}/src">

</target>
<target name="initialize_build">

<wtkpackage
autoversion="${flag.autoversion}"
jadfile="${path.build.output}/${midlet.name}.jad"
jarfile="${path.build.output}/${midlet.name}.jar" obfuscate="false"
preverify="${flag.preverify}">
<fileset dir="${path.build.classes}">

</fileset>
<zipfileset src="${project.root}/kxml.jar"/>
</wtkpackage>
<antcall target="obfuscate"/>
</target>
<target if="flag.should.obfuscate" name="obfuscate">
<wtkobfuscate jadfile="${path.build.output}/${midlet.name}.jad" jarfile="${path.build.output}/${midlet.name}.jar">

<wtkpreverify

</target>
<target depends="jar" name="deployable">

<delete includeEmptyDirs="true" quiet="true">
<fileset dir="${path.build.output}" includes="*,*/**"/>
</delete>
<antcall target="package">

</antcall>
</target>
<target depends="deployable" name="run">
<echo message="Running emulator…"/>
<wtkrun
device="${run.device.name}"
jadfile="${path.build.output}/${midlet.name}.jad"
trace="${run.trace.options}" wait="true"/>
</target>
<target name="clean">
<delete includeEmptyDirs="true" quiet="true">
<fileset dir="${path.build}" includes="*,*/**"/>
</delete>
</target>
</project>
三 运行
运行命令：ANT -f E:\Ant\Build.xml
有个地方是要注意的，<wtkjad jadfile="${midlet.name}.jad"
name="${midlet.name}" vendor="" version="">，如果vendor="" version=""
值为空的话，调用手机模拟器的时候会出错的。
虽然结构不是很清晰，显得有点粗糙，也算是告一段落。
