I'm getting these errors when I try and build my project, it looks like it thinks I have 2 of the same library, but I'm not sure why:

This is my top level gradle build file:

buildscript {
repositories {

maven {

I think this error happened after an upgrade to android studio but I can't remember for sure. My android studio version now is 3.2.1. I was able to get this project to build previously.
In Android Studio, dependencies allows us to include external library or local jar files or other library modules in our Android project. For example: Suppose I want to show some images in ImageView. But I'm using Glide Library to enhance the smoothness of application.
To add a dependency to your project, specify a dependency configuration such as implementation in the dependencies block of your module's build.gradle file.
Clear your project directory Obviously, try to clean your project from android studio : “Build -> Clean Project”. This will clear your build folders. Clear the cache of Android Studio using “File -> Invalidate Caches / Restart” choose “Invalidate and restart option” and close Android Studio.
In your top level Gradle file add class path for google service plugin.
dependencies {
classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.0.1'
}
you should check for your internet connection, proxy or firewall.
OR
cross check to disable Gradle Offline by following.
Windows:
Settings >Gradle >Disable Offline Work
Mac:
Preferences > Build, Execution, Deployment >Gradle >Disable Offline Work
