任何人都可以帮助我知道这些标记在build.xml文件中的作用吗?build.xml in ant

1)<property file="" location="."/> 
2)<property environment=""/> 
3)<property name="" value=""/> 
4)<path> id="classpath.base" 
5)<pathelement> location="$some.jar"/> 
6)<path> id="classpath.build"> 
7)<path> id="classpath.test"> 
8)<target></target> 

谢谢

<property environment=""/>是系统环境变量
<property name="" value=""/>与值

location属性指定单个文件或相对目录到项目的基本目录(或绝对文件名)定义变量,而path属性接受冒号或以分号分隔的位置列表。 path属性旨在与预定义路径一起使用 - 在任何其他情况下,应优先考虑具有location属性的多个元素。

Targets包含任务元素。构建文件的每个任务元件可以具有id属性,并且可以通过稍后提供给此

<project name="MyProject" default="dist" basedir="."> 
    <description> 
     simple example build file 
    </description> 
    <!-- set global properties for this build --> 
    <property name="src" location="src"/> 
    <property name="build" location="build"/> 
    <property name="dist" location="dist"/> 

    <target name="init"> 
    <!-- Create the time stamp --> 
    <tstamp/> 
    <!-- Create the build directory structure used by compile --> 
    <mkdir dir="${build}"/> 
    </target> 

    <target name="compile" depends="init" 
     description="compile the source " > 
    <!-- Compile the java code from ${src} into ${build} --> 
    <javac srcdir="${src}" destdir="${build}"/> 
    </target> 

    <target name="dist" depends="compile" 
     description="generate the distribution" > 
    <!-- Create the distribution directory --> 
    <mkdir dir="${dist}/lib"/> 

    <!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file --> 
    <jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/> 
    </target> 

    <target name="clean" 
     description="clean up" > 
    <!-- Delete the ${build} and ${dist} directory trees --> 
    <delete dir="${build}"/> 
    <delete dir="${dist}"/> 
    </target> 
</project> 
的值被称作
