I have failing build on a Bitbucket CI server:

> Could not resolve all artifacts for configuration ':classpath'.
   > Could not find aapt2-proto.jar (com.android.tools.build:aapt2-proto:0.3.1).
     Searched in the following locations:
         https://jcenter.bintray.com/com/android/tools/build/aapt2-proto/0.3.1/aapt2-proto-0.3.1.jar

I searched similar questions that suggested the Google Maven repository is missing, but I am not missing it. Top level build file:

buildscript {

    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.jakewharton:butterknife-gradle-plugin:8.8.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven { url "https://jitpack.io" }
    }
}

And my app level build file:

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
        google()
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.26.1'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    google()
    mavenCentral()
}

Try moving the google() method to the top of its execution block.

Maybe it's the order of repositories it searches in that causes the issue.

So for example, change this:

repositories {
  maven { url 'https://maven.fabric.io/public' }
  google() // from here
  mavenCentral()
}

To this:

repositories {
  google() // to here
  maven { url 'https://maven.fabric.io/public' }
  mavenCentral()
}

If that doesn't help, instead of calling the google() method, try changing it to this:

maven {
  url 'https://maven.google.com/'
  name 'Google'
}

UPDATE

If all of the above didn't help - make sure your gradle version is at least 3.0.0:

dependencies {
  classpath 'com.android.tools.build:gradle:3.2.1'
}

And the gradle-wrapper version is at least 4.1:

Usually located here: project_name/gradle/wrapper/gradle-wrapper.properties

distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.2-all.zip

Upgrading the Gradle wrapper (in gradle-wrapper.properties) to gradle-4.10.2-all.zip fixed the problem to me.

Update Gradle Version

From the android gradle release page you can check compatible version for your gradle plugin.

Update gradle version in gradle-wrapper.properties located inside yourProject/gradle/wrapper

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4.0-all.zip

Plugin version  Required Gradle version

   2.3.0+             3.3+
   3.0.0+             4.1+
   3.1.0+             4.4+

Note that order matters. google() should be top of any plugin repo.

For Android Studio version > 3.0

buildscript {
  repositories {
      google() // move it to top
      jcenter()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:3.2.1' // your Android Studio Version
  }
} 
allprojects {
  repositories {
      google() // move it to top
      jcenter()
}

google() plugin is needed since Android Studio version 3.0 or higher.

For Android Studio version < 3.0

buildscript {
  repositories {
      maven {
       url 'https://maven.google.com/'
       name 'Google'
      }
      jcenter()
  }
  dependencies {
      classpath 'com.android.tools.build:gradle:2.3.0' // your Android Studio Version
  }
} 
allprojects {
  repositories {
      maven {
       url 'https://maven.google.com/'
       name 'Google'
      }
      jcenter()
}
