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?

This issue occurs when the main .class file moved or not found because you changed the directory for committed/shared the project into the git or another repository.

To Resolve this issue -->
Remove existing run configuration and new one.
Find the parent pom.xml or project pom.xml and open cmd/command prompt and run the below commands,

1. mvn clean install package
2. mvn eclipse eclipse
I tried all the answers but finally what worked for me was deleting the project from eclipse workspace and importing it again.
