Answer 1

Try cleaning your project, that might help.

On eclipse, click on the menu item above called "Project", then click on "Clean Build". On that screen, check the checkbox that says "Clean projects selected below", select the project(s) that's giving you problems, and click Ok.

It will rebuild your project and that usually helps with strange eclipse errors like this.

Answer 2

Please see your .classpath file, and see if all reference lib projects or src projects are added with correct path and name.
