线程“主”中的异常java.lang.NoClassDefFoundError：DiServer<错误名称：ds / DiServer> [英] Exception in thread "main" java.lang.NoClassDefFoundError: DiServer <wrong name: ds/DiServer>

问题描述

这是我害怕的一个非常尴尬的问题之一。

This is one of those terribly embarrassing questions I'm afraid.

我在Eclipse中有一个程序：

I have a program in Eclipse:

    package ds;
    public class DiServer {
 public static void main(String[] args) {
    int foo = 0;
    int bar = 0;
    /*bla*/
    }
    }

？这在Eclipse中运行时工作得很好。

Simple right? This works completely fine when run in Eclipse.

我想从命令行运行。我已经复制了bin文件夹，其中的ds文件夹和dsServer中的DiServer.class和.classpath

I want to run this from command line. I have copied bin Folder, with the ds folder inside it and DiServer.class in ds, and .classpath

我把它们放到一个单独的文件夹C：\我的文档\DiTest，打开命令提示符，转到C：\My Documents\DiTest\ds\并键入 java DiServer

I have put these into a separate folder, C:\My Documents\DiTest, opened command prompt, gone to C:\My Documents\DiTest\ds\ and typed java DiServer

我得到的错误是线程main中的异常java.lang.NoClassDefFoundError：DiServer<错误名称：ds / DiServer> ...找不到主要类：DiServer。程序将退出。

我尝试过java -classpath。 DiServer，java -classpath ../ .. DiServer，将.classpath移动到ds文件夹，但我似乎无法得到这个结果。我99％确定这是一个类路径问题，但我无法解决如何解决它。

I have tried java -classpath . DiServer, java -classpath ../.. DiServer, moving .classpath to the ds folder, but I can't seem to get round this. I'm 99% sure it's a classpath problem but I can't work out how to fix it.

我会非常感谢任何帮助，一如往常，和惯例提供一品脱总是站立。

I would greatly appreciate any help as always, and the customary offer of a pint always stands.

提前非常感谢，

M

推荐答案

您的全名是 ds.DiServer ，而不是 DiServer 。从 C：\My Documents\DiTest ：

You class full name is ds.DiServer, not DiServer. From C:\My Documents\DiTest:

java -cp . ds.DiServer

And voilà。
