java如何打包

建议使用ANT打包工具，下载地址:http://apache.justdn.org/ant/binaries/apache-ant-1.6.5-bin.zip

此工具用java编写，跨平台，能实现很多功能：编译、打包、运行、文件 *** 作、数据库 *** 作、自定义任务等。

主要使用方法：在工程目录下编写build.xml配置文件，然后运行ant即可：

#ant

或

#java -jar ant.jar

下面给你提供一个例子，是jakarta-oro-2.0.8的包的build.xml

<?xml version="1.0"?>

build.xml文件的编写可参见ant发行版中的使用文档

你也可以自己编写脚本打包，使用jdk发行版中的jar命令，例如：

#jar cmf myManifestFile myFile.jar *.class

注意还需要自己编写MANIFEST.MF文件配置包属性。具体可以参见javadoc

当然还可以使用集成开发环境提供的打包工具，如JBuilder提供打包工具，但这样程序的移植性不强，建议不要使用，就使用ant比较好。

里面1.0-1.8的版本和插件。

英文看不明白的话可以用这个站 直接整站在线翻译，或者使用金山快译。

21CN提供了1.8升级版。可能必须是电脑先装有了1.0以后才能升级的。

可以先在官方网下载个1.0安装,然后再用21CN下载的，就可以升级。不过官方网也有1.8了。
