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?

The solution to this was the following:

* Close Eclipse/STS
* Use a file explorer on your operating system to navigate to your workspace (In my case, I'm on Windows so I used Windows Explorer)
* Delete the `.metadata` directory (or to be safe, copy the directory somewhere else to be safe, then delete it)
* Restart Eclipse/STS

Is there a more improved answer than this? I don't want to look like I'm trying to boost my own reputation points, so if someone can provide a better answer then please do so.
A quick and easy fix is to directly run your SpringBootApplication class (i.e. Right click, Run As -> Spring Boot App). This runs the app and creates a run configuration automatically.
