Difference between google() and maven { url 'https://maven.google.com' }

Question

Is there any difference between google() and maven { url 'https://maven.google.com' } in build.gradle file and if there is any, what is it?

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
        // OR
        google()
    }
}

maven.google for android studio 2.3 and below versions. google() for android studio 3.0.0 and above. ( it's the same fuctionality) — , Sep 28 '17 at 11:04

The google() repository is a shortcut to Google's maven repository. It was introduced in Gradle 4.x+. The actual repository URL used is `"https://dl.google.com/dl/android/maven2/" as specified here. https://maven.google.com actually points to the same repository.

However, if you are planning to use the google() shortcut, you need Gradle 4.x+, Android Studio 3.x+ and Gradle plugin for Android 3.x+.

Small correction to the answer above. If you try to go to https://dl.google.com/dl/android/maven2/ it gives you a 404. The correct url to google maven repository is:

https://dl.google.com/dl/android/maven2/index.html or just https://maven.google.com

Here you can check all the supported libraries and the latest versions.

This should have been posted as a comment to Jayson's answer. – Rodrigo García Oct 01 '18 at 18:39
https://dl.google.com/dl/android/maven2/index.html is also 404 now – drakeet May 11 '21 at 07:24

When using gradle, you can mention multiple repositories which the build tool (gradle) uses to resolve dependencies mentioned in your project.

repositories {
    jcenter()
    maven { url 'https://maven.google.com' }
    google()
}

In the above scenario, you're mentioning 3 repositories which gradle can use to resolve dependencies—all of which are Maven repositories.

1. jcenter()

Means the JCenter Maven repository.
This is a shortcut available in later versions of gradle

2. { url 'https://maven.google.com' }

This means you are referring a Maven repo hosted at the URL which can be used by gradle to resolve the dependencies.
If you want, you can actually enter the URL for JCenter and this would be the same as mentioning jcenter() in the gradle file.

3. google()

This means the Google Maven repository
Similar to the notation maven(), this can be used in later versions of gradle only

Difference between google() and maven { url 'https://maven.google.com' }
