Could not find gradle.plugin.chrisney:enigma:1.0.0.8. #9

Hi there,

I have initialised my app with Github in Android Studio by going to VCS / Import into Version Control / Share Project on GitHub.
I have never done that but I hope that this is ok.
After implementing the described information I get the following error:

Could not find gradle.plugin.chrisney:enigma:1.0.0.8.
Searched in the following locations:
