The new version of Android Studio 2020 is stuck in Gradle downloading / sync failed / slow download / download timed out pro-test effective solution

This problem stuck me for three days

My head hurts!

final solution

Create a new project and change two files

Change it to this in build.gradle:

buildscript {
    repositories {
        maven {
            url "http://maven.aliyun.com/nexus/content/groups/public/"
        }
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.1"

        // 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
}

For the gradle version, I choose 4.1.1. The gradle versions in the upper and lower files should be unified.

Change gradle-wrapper.properties like this

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.1.1-all.zip

After downloading and loading in three minutes without reporting an error, Alibaba Cloud is awesome! ! ! ! !

In the future, I will solve all bugs and problems related to Marven and Gradle through aliyun mirroring!
