Unable to convert classes to dex format GoogleMobileAds SDK conflicting Facebook SDK

I made a 2d game and used GoogleMobileAds SDK to implement ads into the game. Yesterday, I imported Facebook SDK so Player could share it`s score in Facebook. When I tried to compile it, it presented the bottom error message ("Unable to convert classes to dex format").

Wierd thing: When I build my project without the facebook SDK it doesn`t display this error message, and the same way opposite, when I build my project (only the share button, withought the google mobile ads in it), it works good aswell!

What I think it might be is that the GoogleMobileAds Plugin is conflicting with the FaceBook plugin. (I already know that this message occours because of doubled jar files, but I can`t tell which. Maybe you could help me)

That`s the error:
