Answer 1

I suggest printing out what's on your classpath from within your app (see this answer). That way you'll know exactly what classpath your app is using, if there's anything missing or any collisions.

Answer 2

Problem is solved now. It was a mistake between guice 3.0 and guice-3.0.0, because both are having the same maven artifact-id but group-id was different.

Answer 3

Open the property of your project and add a dependency library.
