Installing Ant
1. choose a directory and copy the distribution files there, and the directory will be named as "ANT_HOME"
2. set the environment
windows:    set ANT_HOME=C:/apache-ant-xx
                set JAVA_HOME=C:/jdk
                set PATH=xxxx;%ANT_HOME%/bin

Using Ant
1. write a class
E:/anttest/src/oata/HelloWorld.java
package oata;
public class HelloWorld{
    public static void main(String[] args){
        System.out.println("hello World!");
    }
}
2. write build.xml
<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>
3. execute:
E:/anttest/ant

Running Ant
ant
* runs the default build.xml
ant -buildfile test.xml
* runs the test.xml
ant -buildfile test.xml dist
* runs using the test.xml in the current directory, on the target called dist
ant -buildfile test.xml -Dbuild=build/classes dist
* runs using the test.xml file the current directory, on the target called dist, setting the build propety to the value build/classes
ant -lib /home/ant/extras
* runs picking up additional task and support jars from the /home/ant/extras location
