Android libGdx problem(Error)

Imam problem, ko hočem svojo kodo zagnat mi eclipse vrže napako. Možno je da je v kodi1 ali pa v koda2 kej narobe. Problem zgleda takole:

Exception in thread "main" java.lang.NoClassDefFoundError: com/badlogic/gdx/jnigen/NativeCodeGenerator

V knjižnicah, ki jih imaš includane v projekt, class NativeCodeGenerator ne obstaja.
