 1、下载安装下载:http://ant.apache.org

    需要设置的环境变量:

    ANT_HOME:ant的安装目录

    JAVA_HOME:jdk的安装目录

    PATH:把%ANT_HOME%\bin目录加到path变量,以便于从命令行下直接运行ant

    假定ant解压在c:\ant   jdk装d:\j2sdk1.4.0

    则在命令行下执行以下命令:

set ANT_HOME=c:\ant
set JAVA_HOME=D:\j2sdk1.4.0
set PATH=%PATH%;c:\ant\bin

    2、工程文件目录结构:

    一个ant 工程目录结构:

    C:\workspace\ant.test:工程主目录

    \src :源程序目录

    \build\classes :编译后的 class 文件目录

    \lib :开发工程所需要的类库目录,比如开发数据库时所需要的 jdbc lib(这次没用到)

    \jar :打包好的 jar 程序目录(这次没用到)

    \build.xml :工程配置文件\build.propertiees:工程资源文件

    2、建立工程描述文件和建立工程资源文件

    建立工程描述文件build.xml

<?xml version="1.0"?>

<project default="main" basedir=".">

    <echo message="pulling in property files" />
    <property file="build.properties" />

    <target name="init">
        <echo message="init. delete the old class files. and create the new folds." />
        <delete dir="${classpath}" />
        <mkdir dir="${classpath}" />
    </target>

    <target name="compile" depends="init">
        <echo message="compile the java source files." />
        <javac srcdir="src\hello\ant" destdir="${classpath}" />
    </target>

    <target name="main" depends="compile">
        <echo message="calling java to run this java project." />
        <java classname="hello.ant.HelloAnt">
            <classpath>
                <pathelement path="${classpath}" />
            </classpath>
        </java>
    </target>

</project>

    建立工程资源文件:build.properties

    文件内容是下面一行内容:

classpath=build\\classes

    4、建立java源文件:hello.ant.HelloAnt.java

package hello.ant;

public class HelloAnt {
    public static void main(String[] args) {
        System.out.println("hello ant, the first time using ant... it is great.");
    }
}

    5、编译:

C:\workspace\ant.test>ant -buildfile build.xml
Buildfile: build.xml
     [echo] pulling in property files

init:
     [echo] init. delete the old class files. and create the new folds.
   [delete] Deleting directory C:\workspace\ant.test\build\classes
    [mkdir] Created dir: C:\workspace\ant.test\build\classes

compile:
     [echo] compile the java source files.
    [javac] Compiling 1 source file to C:\workspace\ant.test\build\classes

main:
     [echo] calling java to run this java project.
     [java] hello ant, the first time using ant... it is great.

BUILD SUCCESSFUL
Total time: 890 milliseconds

C:\workspace\ant.test>
