Answer 1

Clean your google-play-services_lib project. Check the property of your library project which may have error in java build path. You have to tick the google-play-service.jar in Order and Export tab.

Answer 2

Make sure you have project.properties in the project. It's needed by eclipse. If you don't have it, kindly copy it from another existing android project, clean and rebuild your project.

Answer 3

Right click on google-play-services_lib projects and select properties and change the target od project
