文档结构为:
<project>
<property/> 全局变量的定义
<property/>...

<target name="1"> 任务组(tasks)
<javac></javac> 一项javac任务
...
<oneTask></ontTask> 一项其它任务
</target>

<target name="2">
<javac></javac>
...
<oneTask></ontTask>

project代表一个项目，
default:运行到名称为"dist"的target(任务组)
basedir:基准路径。
-->
<project default="dist" basedir=".">

<!--
===================================================================
定义属性（property tasks）
最好把用到的路径呀，名称呀都在这里定义成全局变量
例：定义
<property name="a" value="hello"/>
以后就可以这样用它：
<property name="b" value="${a}/b"/>
现在:b=="hello/b"
===================================================================
-->

<!--主要的系统环境属性-->
<property environment="env"/><!--取window,unix...的环境变量-->
<property name="java.home" value="${env.JAVA_HOME}"/>
<property name="ant.home" value="${env.ANT_HOME}"/>

<!--主要的app环境属性-->
<property name="app.name" value="hello-ant"/>
<property name="app.jar" value="${app.name}.jar"/>
<property name="app.copyright" value=" Copyright (c) 2002 The Neusoft Software Foundation. All rights reserved."/>

<!--app中src的属性-->
<property name="src.dir" value="src" />
<property name="src.main" value="${src.dir}/main"/>
<property name="src.script" value="${src.dir}/script"/>

<!--app用到的lib-->
<property name="lib.dir" value="lib"/>

<!--app的build目录中-->
<property name="build.dir" value="build" />
<property name="build.classes" value="${build.dir}/classes"/>
<property name="build.docs" value="${build.dir}/docs"/>
<property name="build.docs.api" value="${build.docs}/api"/>

<property name="dist.docs" value="${dist.dir}/docs"/>
<property name="dist.lib" value="${dist.dir}/lib"/>

<!--app的docs目录中-->

定义一组路径以后可以通过id重用这组路径 ，例：
<javac srcdir="src/main" destdir="build/classes">
<classpath refid="classpath"/>
</javac>
-->
<path id="classpath">
<!--本项目只有一个java，用不上classpath，这里只是做个例子-->
<pathelement location="${build.classes}"/>
<pathelement path="${java.home}/lib/tools.jar"/>
</path>

init 准备目录(File Tasks)
