Android Studio fastutil.jar 一直在sync

因为fastutil.jar文件需要翻墙才能sync成功，所以需要在build.gradle中添加aliyun的服务器地址

buildscript {
    repositories {
        maven{ url = "http://maven.aliyun.com/nexus/content/groups/public/" }
        google()
        jcenter()
        
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven{ url = "http://maven.aliyun.com/nexus/content/groups/public/" }
        google()
        jcenter()
        
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
