Ant

新建工程Ant Demo 建立一个src文件夹 和build.xml 文件

src中建立Hello.java文件

package org.zbq.ant;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.util.Date;

public class Hello extends JFrame{
	private JFrame frame;
	private JButton but;
	
	public Hello(){
		this.frame = new JFrame("Hello");
		this.but = new JButton("Time");
		frame.setBounds(500, 300, 300, 400);
		frame.add(but, BorderLayout.CENTER);
		
		but.addActionListener(new ActionListener(){
			@SuppressWarnings("deprecation")
			public void actionPerformed(ActionEvent e)
             {
             	Date date = new Date();
                JOptionPane.showMessageDialog(frame, 
                 	date.toLocaleString(), "Now Time", JOptionPane.YES_OPTION);
             }
			
		});
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setVisible(true);
	}
	
	
	public static void main (String[] args) {
		new Hello();
	}
}

build.xml

<?xml version="1.0" encoding="UTF-8"?>
<project basedir="." default="run">
	<property name="src" value="src"/>
	<property name="classes" value="classes"/>
	<property name="hello_jar" value="Hello.jar"/>

	<target name="init">
		<mkdir dir="${classes}"/>
	</target>

	<target name="compile" depends="init">
		<javac srcdir="${src}" destdir="${classes}"/>
	</target>

	<target name="build" depends="compile">
		<jar jarfile="${hello_jar}" basedir="${classes}">
			<manifest>
				<attribute name="Build-By" value="${user.name}"/>
				<attribute name="Main-Class" value="org.zbq.ant.Hello"/>
			</manifest>
		</jar>
	</target>

	<target name="run" depends="build">
		<java classname="org.zbq.ant.Hello" classpath="${classes}"/>
	</target>

	<target name="clean">
		<delete dir="${classes}"/>
		<delete file="${hello_jar}"/>
	</target>

	<target name="rerun" depends="clean,run">
		<ant target="clean"/>
		<ant target="run"/>
	</target>
</project>

在终端到工程目录下

运行ant 会自动构建

ant target+name 会执行单个target
