使用ant编译并生成jar包

使用ant生成可执行jar文件，双击可以打开窗口。

1.写一个创建窗口的类

package com.anllin.ant.test;   import java.awt.Color; import java.awt.Dimension;   import javax.swing.JButton; import javax.swing.JFrame;   public class Window {     public static void main(String[] args)     {        JFrame frame = new JFrame();               frame.setSize(new Dimension(200,300));        frame.setBackground(new Color(200,200,200));        frame.setAlwaysOnTop(true);        frame.getContentPane().add(new JButton("Ant"));        frame.setVisible(true);               frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     } }

 

2.使用ant编译并生成jar包

<?xml version="1.0" encoding="UTF-8"?> <project name="myAntProject" basedir="." default="package">     <property name="compile" value="compile"/>     <property name="dist" value="dist"></property>     <target name="init"></target>     <target name="preprocess" depends="init">        <mkdir dir="${compile}"/>        <mkdir dir="${dist}"/>     </target>     <target name="compile" depends="init,preprocess"></target>     <target name="package" depends="compile"></target>     <target name="mycompile" depends="preprocess">        <javac srcdir="src" destdir="${compile}"></javac>     </target>     <target name="dist" depends="mycompile">        <jar destfile="${dist}/package.jar" basedir="${compile}">            <manifest>               <attribute name="Build-By" value="${user.name}"/>               <attribute name="Main-Class" value="com.anllin.ant.test.Window"/>            </manifest>        </jar>     </target> </project>
