Editor does not contain main type in Eclipse

I got this message when running my project in Eclipse, and I am sure that I have a main in my project. I tried cleaning, closing and re-opening it, but nothing works. Can anyone hel开发者_StackOverflow社区p me please?

The currently opened source code doesn't have a public static void main(String[] args) method. Ensure that you're opening and focusing the right source code which contains the method and then press Ctrl+F11 to execute it.

It could be many things.

Try to clean your workspace first and check your configuration used to start your project.

Sometimes you can get this error if your .java file is misplaced outside the src folder..

Try to verify that you .java file is under src folder.
