Eclipse错误 - “找不到或加载主类” [英] Eclipse Error - "Could Not Find Or Load Main Class"

问题描述

我开始使用Eclipse开发我的java程序（没有移动/触摸任何设置）。

我尝试运行Java程序，我得到这个消息：

 错误：找不到或加载主类CLASSNAME 
  

这个事情发生在我所有的java程序中，包括我之前开发的（在Eclipse上运行没有问题）。不过昨天并非如此，我能够运行开发的程序没有问题。

我没有卸载/更改我的Java安装。开发的程序运行没有问题，当我使用另一个IDE来运行它...

如何解决这个问题？
谢谢！

解决方案

我遇到同样的问题，我在配置构建路径中删除了一个jar文件它开始为我工作正常。

I started using Eclipse today to develop my java programs (did not move/touch any settings).

I try to run the Java programs, and I get this message:

Error: Could not find or load main class CLASSNAME

This happens for ALL my java programs, including those I developed before (and ran without problems on Eclipse). However, this was not the case yesterday; I was able to run developed programs without problem.

I did not uninstall/change my Java installation. The developed programs run without problem when I use another IDE to run it...

How to fix this? Thanks!

解决方案

I had same problem one of the jar files was missing which i removed in the configure build path it started working fine for me.
