以前，在Android Studio Arctic Fox版本之前，我们是在build.gradle的allprojects闭包里面添加依赖仓库路径的。如下：

allprojects {
  repositories {
    google()
    mavenCentral()
    jcenter() // Warning: this repository is going to shut down soon
  }
}

在Arctic Fox版本之后，我们要在settings.gradle的repositories闭包里面添加。如下：

dependencyResolutionManagement {
  repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
  repositories {
    google()
    mavenCentral()
    jcenter() // Warning: this repository is going to shut down soon
  }
}
rootProject.name = "My Application"
include ':app'
