我的build.xml放到JunitTestuild，構造這個文件才可以使用ant命令來執行，包括編譯、打包、測試junit用例
<?xml version="1.0" encoding="UTF-8" ?>
<project name="anita" default="main" basedir="../">
<property name="app.name" value="sayhello" />
<property name="build.dir" value="build/classes" />
<target name="JUNIT">

</target>
<target name="compile" depends="JUNIT">
<mkdir dir="${build.dir}"/>
<javac srcdir="src/" destdir="${build.dir}" >
<include name="**/*.java"/>
</javac>

如果是win系統，在DOS窗口下進入你的工作目錄，并到 ../JunitTest/build下，執行ant runtests命令，會看到如下信息
D:TEMPJunitTestTestCaseuild>ant runtests
