buildscript {
    ext.kotlin_version = '1.3.70'
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
        maven { url 'https://maven.aliyun.com/repository/google' }
        maven { url 'https://maven.aliyun.com/repository/gradle-plugin' }
        maven { url "https://jitpack.io" }
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.6.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public' }
        maven { url 'https://maven.aliyun.com/repository/jcenter' }
