java如何打包
建议使用ANT打包工具,下载地址:
此工具用java编写,跨平台,能实现很多功能:编译、打包、运行、文件操作、数据库操作、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。
如何把java程序打包成exe
将java源码打包成exe的步骤如下:1、最简单直接的方法,选择想打包的程序,右键export;2、选择Java选项,再选择RunnableJARfile选项,点击next按钮;3、选择程序的主类,还有Main函数的类和输入要导出的位置,点击finish;4、在电脑上,设置好Jar文件的打开方式(别默认用解压缩的工具打开就行),双击即可运行。
Java项目写完后怎么怎么打包?
Java项目的打包成jar文件:
eclipse 中选择要发布的工程右键单击,选择export
然后在列表中选择jar(不一定马上看到,但是可以找到的)
确定后下一步,选择你要发布的类,反正你要用的到的类全部选择进去包括图片或者音乐(音乐和图片的引用方式有关系,另当别论),然后取个名称,选择路径
再下一步两次,然后选择main-class,就是你运行程序时运行的哪个类,选择后单击finish,jar文件应该打包成功了,双击可以直接运行。
如何将java代码打包成jar包
方法:
1、启动eclipse;
2、在eclipse中建立好工程与类并写好代码;
3、点击“File-Export”;
4、在弹击的界面中选择“Java-JAR file”,再点击“Next”;
5、选择要打包的文件,再点击“Browse”;
6、在弹出的界面中选择好打包后的文件的存放路径,再输入文件名,最后点击“保存”;
7、点击“Finish”;
8、打包成功。
