问题

Android Studio一直 Download fastutil-x.x.x.jar， 应该是被墙了。

解决方法

在项目目录下面的 build.gradle 里面添加 aliyun：

buildscript {
    repositories {
        maven {
            url 'https://maven.aliyun.com/repository/google';
        }
        maven {
            url 'https://maven.aliyun.com/repository/public';
        }
        maven {
            url 'https://maven.aliyun.com/repository/jcenter';
        }
        google()
        mavenCentral()
    }
    dependencies {
        ...
    }
}
