Eclipse类没有突然发现

Question

Eclipse suddenly won't run any code anymore. Here is the error message for anything I try to run:

Error: Could not find or load main class sa0

Caused by: java.lang.ClassNotFoundException: sa0

It says that the class doesn't exist, when it does. Did I delete something by accident? How do I fix this?

Answer 1

You might want to check your project's build path or carefully read the stack trace of the error. Also worth checking on your project's libraries if you are using one. ClassNotFoundException has also been an issue on some versions of eclipse and googling that might help.
