Java构建工具

<!--源目录和目标目录由属性 srcdir 和 destdir 配置；
编译位于目录 src 中的 Java 源文件，并将类文件放入目录 dest 中-->
<javac srcdir="src" destdir="dest"/>

<!--名为 init 的目标使用任务 mkdir 创建目录 build-->
<target name="init">
    <mkdir dir="build"/>
</target>
<!--名为compile的目标，用于通过javac Ant任务编译Java源代码。
这个target依赖于target init，所以如果你在命令行运行它，init会先被执行。-->
<target name="compile" depends="init">
    <javac srcdir="src" destdir="build"/>
</target>

<!--项目包含一个或多个目标并定义可选属性（例如名称）来描述项目-->
<project name="example-build">
    <target name="init">
        <mkdir dir="build"/>
    </target>

    <target name="compile" depends="init">
        <javac srcdir="src" destdir="build"/>
    </target>
</project>

<project name="my-app" default="dist" basedir=".">
    <!-- 为此构建设置全局属性-->
    <property name="src" location="src"/>
    <property name="build" location="build"/>
    <property name="dist" location="dist"/>
    <property name="version" value="1.0"/>

    <target name="init">
