First of all thank you ceryle, for making very nice & useful library. I have used this library in my one project which was version 1.4.9, that was working very good. But recently i have added 2.1.0 version but it is showing this error

Error:(49, 13) Failed to resolve: com.github.ceryle:RadioRealButton:v2.1.0 Show in File Show in Project Structure dialog

if I change it to 1.4.9 then its work good and don's show any error.
