Android Studio导入项目一直卡在gradle sync 的download jcenter

将build.gradle改为

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        maven {
            url 'https://maven.aliyun.com/repository/jcenter'
        }
        maven {
            url 'https://maven.aliyun.com/repository/google'
        }
        jcenter()
        google()
        dependencies {
            classpath 'com.android.tools.build:gradle:3.5.2'

            // NOTE: Do not place your application dependencies here; they belong
            // in the individual module build.gradle files
        }
    }
}

allprojects {
    repositories {
        maven {
