I have looked everywhere on the internet and tried everything the forums say to do and nothing works  This error keeps coming up  I have tried running my java project  not for android  even the drop down run as button doesn t work because it says  none applicable

It happens when sometimes we copy or import the project from somewhere. The source folder is a big thing to concern about.

One simple technique is, create a new project, inside the source folder, create a new class and paste the content over there.

It will work...

Hope it helps.

Eclipse needs to see a main method in one of your project s source files in order to determine what kind of project it is so that it can offer the proper run options   public static void main String   args    Without that method signature  or with a malformed version of that method signature   the Run As menu item will not present any run options

Make sure the  m  in main   is lowercase this would also cause java not to see your main method  I ve done that several times unfortunately
