Ant进行javac/java/jar/javaDocs的简单操作实例

Java类：

package com.lxitedu.ant;   
  
public class HelloWorldTest {   
  public static void main(String[] args) {   
    System.out.println("Hello,World!");   
  }   
}  
build.xml ：

<project name="HelloWorld" default="say">  
    <property name="src.dir" location="src"></property>  
    <property name="build.dir" location="build"></property>  
    <property name="Demo.dir" location="Demo"></property>  
  
    <target name="say">  
        <echo message="打印main方法">  
        </echo>  
        <ant target="init"/>  
        <ant target="javac"/>  
        <ant target="jar"/>  
        <ant target="java"/>  
        <ant target="javaDocs"/>  
    </target >  
       
    <target name="init">  
        <mkdir dir="${build.dir}"/>  
        <mkdir dir="${Demo.dir}"/>  
        <echo message="init完成...."/>  
    </target>  
       
    <target name="javac">  
        <javac  srcdir="${src.dir}" destdir="${build.dir}"/>  
        <echo message="javac完成...."/>  
    </target>  
       
    <target name="jar">  
        <jar destfile="${Demo.dir}/helloWorld.jar" basedir="${build.dir}"/>  
        <echo message="jar完成...."/>  
    </target>  
    <target name="java">  
        <java className="com.lxitedu.ant.HelloWorldTest">  
            <classpath location="${Demo.dir}/helloWorld.jar"/>  
        </java>  
        <echo message="java完成...."/>  
    </target>  
    <target name="javaDocs">  
        <mkdir dir="./doc" />  
        <javadoc packagenames="com.lxitedu.ant.*" sourcepath="${src.dir}" destdir="./doc">  
        </javadoc>  
        <echo message="javaDocs完成...."/>
