如何从.java创建JAR [英] How do I make a JAR from a .java

问题描述

我正在使用Java应用程序编写一个简单的程序（不是具有项目的应用程序，而是项目中的应用程序; .java），它具有单个框架。这两个文件都是.java，因此我无法编写JAR所需的清单。 MyApp.java就像一个带包的类，然后导入公共类MyApp {并且有一个main函数，但它仍然是.java！如果它有帮助我在JDeveloper 11g中写它...

I was writing a simple program using a Java application (not application that has projects, but application within a project; .java) that has a single frame. Both of the files are .java so I can't write a manifest needed by the JAR. The MyApp.java starts like a class with package, imports then public class MyApp { and has a main function, but it's still .java! I'm writing it in JDeveloper 11g if it helps...

如何从这些文件制作JAR？

Any ideas how to make a JAR from these files?

推荐答案

打开命令提示符。

转到目录你有你的.java文件

Go to the directory where you have your .java files

创建一个目录版本

从命令行运行java编译

Run java compilation from the command line

javac -d ./build *.java

如果没有错误，在构建目录中你应该有你的类树

if there are no errors, in the build directory you should have your class tree

移动到构建目录并做一个

move to the build directory and do a

jar cvf YourJar.jar *

用于添加清单检查jar命令行开关

For adding manifest check jar command line switches
