Adcolony and google play services conflict

when i import adcolony plug to a project containing play services plugin i get this errors

Assets/AdColony/Editor/ADCDependencies.cs(10,23): error CS0433: The imported type Google.JarResolver.PlayServicesSupport' is defined multiple times
Assets/PlayServicesResolver/Editor/PlayServicesResolver.cs(146,56): error CS0433: The imported type Google.JarResolver.Dependency' is defined multiple times

to fix this problem you need to delete PlayServicesResolver folder and importe it again from Play services plugin (not adcolony plugin)
