Answer 1

This solution worked for me

1- In the CordovaLib folder and in the build.gradle file, change the position of the Maven up

Repositories {
   maven {
         url "https://maven.google.com"
   }
   jcenter()
}

2- In the general build.gradle file of the project change the position of Maven up and add google()

Repositories {
   maven {
         url "https://maven.google.com"
   }
   google()
   jcenter()
}

3- In the build.gradle file of the APP folder change the position of Maven up and add google()

buildscript {
    repositories {
        maven {
            url "https://maven.google.com"
        }
        google()
        mavenCentral()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0'
    }
}

// Allow plugins to declare Maven dependencies via build-extras.gradle.
allprojects {
    repositories {
        google()
        mavenCentral();
        jcenter()
    }
}

4 - Finally, run the "Make Project" that is in the upper corner of Android Studio.

ionic cordova platform remove android ionic cordova platform add android ionic build android

And it worked!

Thanks! Had the same issue with cordova project build--setting maven repository as the first entry in both \platforms\android\build.gradle and \platforms\build.gradle files.
