图解教你如何使用ANT打包java程序

1：在eclipse中建立如下的工程

    

    值得注意的就是build.xml文件（这个是重点后面会提到） ，其他HelloWorld中的就是一句简单的输出语句

 

2： 使用build打包（右键然后选择运行），运行后在console下可以看到如下图的过程

     

     当看到了BUILD SUCCESSFUL 表面打包成功了！！！！

 3：然后来到你的**\dist下可以看到刚刚打包成功的包 如下图 ：

     

4：ANT很智能的，如果你已经实现了上面三个过程的打包，再次打包的话它会默认的执行空的操作 （如下图）

     

 

5：最重要的bulid.xml文件（此中有很多ANT内置的命令可以具体参考一下ant的用法）
