Could not find play-services-basement.aar

Question

Yesterday I tried building my app and everything worked fine.

Today, without any changes to the project... All of a sudden I\'m greeted with this warning message tel

Answer 1

jcenter() has had mirrors of some libraries (I guess they are doing intentionally) that should originally available through google() or maven() repositories. When gradle build works, for any library that is used in the project the first place to look for is the repository that is listed first in repositories {.. When the jcenter() mirror does not have the release (e.g com.google.android.gms:play-services-ads:15.0.1 for my case) your gradle is looking for, the build fails with such error.

So, jcenter() should be listed at the last place in repositories {.. parts as below.

   buildscript {
    ext.kotlin_version = '1.2.50'
    repositories {
        google()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        jcenter()
    }...

and

  allprojects {
    repositories {
        google()
        jcenter()
    }
  }
