如何使用ant

第一步：从http://ant.apache.org 下载 apache-ant-1.7.0-bin.zip，解压到你自己的目录，我的：E:\apache-ant-1.7.0

第二步：配置 JAVA_HOME 和 ANT_HOME
配置完成后，打开dos窗口，输入 ant 回车，如果提示：
Buildfile: build.xml does not exist!
Build failed

则说明配置完成

第三步：创建自己的工程
我的工程：test
目录结构：
D:\work\code\test_core\src
D:\work\code\test_core\lib


第四步：编写build.xml

<?xml version="1.0" encoding="UTF-8"?>

<project default="jar" name="test" basedir=".">
  
  <property name="defaulttargetdir" value="./target"></property> 
  <property name="classesdir" value="./target/classes"></property>
  <property name="logsdir" value="./logs"></property>
  <property name="defaulttargetdir" value="./target"></property>
  <property name="final.name" value="test"></property>
  

  <target name="compile" description="o Compile the code" >
    <mkdir dir="${defaulttargetdir}"></mkdir>
    <mkdir dir="${classesdir}"></mkdir>
	<mkdir dir="${logsdir}"></mkdir>

    <javac destdir="${classesdir}" deprecation="true" debug="true" optimize="false" excludes="**/package.html">
      <src>
        <pathelement location="./src"></pathelement>
      </src>
      <classpath>
        <fileset dir="./lib">
          <include name="*.jar"></include>
        </fileset>
      </classpath>
    </javac>
    
  </target>
    
  <target name="jar" description="o Create the jar" depends="compile">
		<copy todir="${classesdir}">
			<fileset dir="./src">
				<include name="**/*.properties" />
			</fileset>
		</copy>    
    <jar jarfile="./lib/${final.name}.jar" excludes="**/package.html" basedir="${classesdir}"></jar>

  </target>
  
  <target name="clean" description="o Clean up the generated directories">
    <delete dir="${classesdir}"></delete>
	<delete file="${lib.dir}/${webapp.name}.jar" />
  </target>



</project>
    

打开dos窗口，进入D:\work\code\test_core\目录，输入ant jar 回车
则test.jar 文件将会被输出到 lib目录下
如果仅仅是编译java源文件，你可以使用 ant compile命令，classes文件将会被输出到 target/classes目录下，如果你在src下有以properties结尾的配置文件，则配置文件将也会被拷贝到 target/classes 目录下，起作用的是：
<copy todir="${classesdir}">
<fileset dir="./src">
<include name="**/*.properties" />
</fileset>
</copy>

web工程：
D:\work\code\test_web\src
D:\work\code\test_web\lib
D:\work\code\test_web\web

build.xml如下：

正在学习中，感觉挺难的！
