如何将多个类文件转换成一个jar文件？ [英] How to convert multiple class files to one jar file?

问题描述

我已经反编译一个jar文件，

I have decompiled a jar file,

和用它制成的两班。在那之后，我试图让这两个类文件的新的JAR文件，使用这种code

and made two classes from it. After that, I tried to make a new jar file with these two class files, using this code

jar cvf AB.jar WinRegistry.class StartPageChangeApplet.class

没有任何错误创建的文件。然而，当我看到关于Java反编译器源$ C ​​$ C，它说：个内错误，意味着我不能让jar文件正确。

The file created without any errors. However, when I look at the source code on Java Decompiler, it says "Internel Error", means that I couldn't make the jar file properly.

我在哪里做做错了吗？

推荐答案

请界定用它制成的两班。其中java编译器（例如器javac.exe）您使用的？你刚才源复制到一个.class文件没有可能在编译？

Please define "made two classes from it". Which java compiler (e.g. javac.exe) are you using? Did you just copy the source to a .class file without compiling maybe?

化java反编译JAD实际显示源$ C ​​$ C，不是阶级字节code。不要被编辑这是说 WinRegistry.class 标题混淆。

The java decompiler JAD actually displays source code, not class bytecode. Don't get confused by the title of the editor which is saying WinRegistry.class.

所以，你不能只保存为的.class 。您需要使用Java编译器将其保存为的.java ，然后将其编译成的.class ：

So you can't just save that as a .class. You need to save it as a .java and then compile it to .class using a java compiler:

javac WinRegistry.java StartPageChangeApplet.java
jar cf AB.jar WinRegistry.class StartPageChangeApplet.class
