android studio 新创建的项目build.gradle内容与以往不一样，需要到settings.gradle文件中修改配置

修改成：

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
//        google()
//        mavenCentral()
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' } //gradle-plugin
        maven { url 'https://maven.aliyun.com/repository/google' } //google
        maven { url 'https://maven.aliyun.com/repository/public' } //public
        maven { url 'https://maven.aliyun.com/repository/jcenter'} //jcenter
    }
}
