Android Studio编译慢的问题

1、download repo.maven.apache卡主
将工程的build.gradle里的mavenCentral注释掉，改为阿里的镜像
maven {
url 'http://maven.aliyun.com/nexus/content/groups/public'
}

2、jcenter.bintray.com 很慢
将工程下的build.gradle中的
jcenter(){url 'http://jcenter.bintray.com/'}
换成
jcenter() { url 'https://maven.aliyun.com/repository/jcenter' }
jcenter() {
// url 'http://jcenter.bintray.com/'
url 'https://maven.aliyun.com/repository/jcenter'

    }


repositories {
    google()
    jcenter() {
        url 'https://maven.aliyun.com/repository/jcenter'
    }
    maven {
        url 'http://maven.aliyun.com/nexus/content/groups/public'
    }
    maven {
        url 'https://jitpack.io'
    }
}

3、 Gradle Build Running 特别慢
