Difference among mavenCentral(), jCenter() and mavenLocal()?

Actually, all 3 are Maven repository. We use these maven repositories to our build by using its URL address or its location in the local file system.

By using URL:

repositories {
    maven { url("https://plugins.gradle.org/m2/") }

By using local file system:

repositories {
    maven { url '../maven-repo' }

Gradle has three “aliases” which we can use when we are adding Maven repositories to our build. These aliases are:

  1. mavenCentral():

The mavenCentral() alias means that dependencies are fetched from the central Maven 2 repository.

repositories {

The URL used to access this repository is https://repo.maven.apache.org/maven2/. The name of the repository is MavenRepo.

  1. jcenter():

The jcenter() alias means that dependencies are fetched from the Bintray’s JCenter Maven repository

  1. mavenLocal():

The mavenLocal() alias means that dependencies are fetched from the local Maven repository.

Jcenter vs. mavenCentral

jcenter() and mavenCentral() is a repository for the Gradle plugin in Android Studio

Earlier versions of Android Studio used mavenCentral(), and after some time, it switched to jcenter.

This is because jcenter() is superior to mavenCentral() in terms of performance and memory footprint:

  • Jcenter is the world’s largest Java repository
  • Jcenter through the CDN service, using the https protocol, highly
    secured, and Android Studio 0.8 version mavenCentral() using the http
  • Jcenter is a superset of mavenCentral, including many additional
  • Jcenter performance is better than mavenCentral
  • mavenCentral will automatically download many IDE-related indexes,
    and these are used less often which are not required.

Work Around:

repositories {
//  jcenter()       // <- remove it
    mavenCentral()  // <- add it
    maven { url "https://plugins.gradle.org/m2/" }
    maven { url "https://repo.spring.io/plugins-release/" }
