如何解决ClassNotFoundException？ [英] How do I resolve ClassNotFoundException?

问题描述

我正在尝试运行Java应用程序，但收到此错误：

I am trying to run a Java application, but getting this error:

java.lang.ClassNotFoundException：

冒号到达后缺少的类的位置。但是，我知道该位置不存在，因为该类位于其他位置。如何更新该课程的路径？它是否与类路径有关？

After the colon comes the location of the class that is missing. However, I know that that location does not exist since the class is located elsewhere. How can I update the path of that class? Does it have something to do with the class path?

推荐答案

你的类路径坏了（这是非常 Java世界中的常见问题）。

Your classpath is broken (which is a very common problem in the Java world).

根据您启动应用程序的方式，您需要将参数修改为 -cp ，您的类路径在MANIFEST.MF或您的磁盘布局中输入。

Depending on how you start your application, you need to revise the argument to -cp, your Class-Path entry in MANIFEST.MF or your disk layout.
