Could not find play-services-tasks-license.aar (com.google.android.gms:play-services-tasks-license:11.8.0)

JCenter doesn't serve https://jcenter.bintray.com/com/google/android/gms/play-services-tasks-license/11.8.0/play-services-tasks-license-11.8.0.aar. This does:

maven { https://maven.google.com/ } 

Swap jcenter() with maven { url "https://maven.google.com" } and try again.
