Hi guys. I am getting the following error while synching gradle after adding dependences for firebase:

Error:Could not find com.google.gms:google-services:3.1.0.
Searched in the following locations:
file:/home/elokudzo/android-studio/gradle/m2repository/com/google/gms/google-services/3.1.0/google-services-3.1.0.pom
file:/home/elokudzo/android-studio/gradle/m2repository/com/google/gms/google-services/3.1.0/google-services-3.1.0.jar
