I have a main method in a package in one of my projects. Say, the package is `com.ant.car`. I am trying to run and/or debug this main method, and I keep getting the error `Could not find or load main class com.ant.car`.

I've searched this problem, and it seems like I can't figure out what is wrong.

1) I've checked run configurations. In Run->Run Configurations, I've checked that the Main class is com.ant.car.

2) I've checked build path. If I right click on the project, I select Build->Build Path, and under the Libraries tab I make sure there are no missing folders with red Xs next to them.

Not really sure what else to do. Any suggestions?

It worked for me: 

 1. Delete metadata from work-space directory.

 2. Import the project again, but selected copy to work-space option.

I think the cause for the error was Non-English characters in the original saved directory.
I spent several hours on this issue, finally it is fixed by doing this:
Properties -> Java Compiler: uncheck the checkbox "use '--release' option"
