如何从 .java 文件制作 JAR? [英] How do I make a JAR from a .java file?

问题描述

我正在使用具有单个框架的 Java 应用程序(不是具有项目的应用程序，而是项目中的应用程序；.java)编写一个简单的程序.这两个文件都是 .java 所以我不能写一个 JAR 需要的 manifest.

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.

MyApp.java 就像一个带包的类，然后导入公共类 MyApp 并有一个 main 函数，但它仍然是 .java 文件！如果有帮助，我会在 JDeveloper 11g 中编写它.

The MyApp.java starts like a class with package, imports then public class MyApp and has a main function, but it's still .java file! I'm writing it in JDeveloper 11g if it helps.

任何想法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.

转到您的 .java 文件所在的目录

Go to the directory where you have your .java files

创建目录build

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

移动到构建目录并执行

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
