AndroidStudio中用到的maven加载库（gradle配置）

  repositories {
            mavenCentral()
            maven { url "https://jitpack.io" }
            maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
            maven { url 'http://maven.oschina.net/content/groups/public/' }
            maven { url 'https://oss.sonatype.org/content/repositories/snapshots/' }
            maven { url "http://maven.springframework.org/release" }
            maven { url "http://maven.restlet.org" }
            maven { url "http://mirrors.ibiblio.org/maven2" }
            maven {
                url "http://repo.baichuan-android.taobao.com/content/groups/BaichuanRepositories/"
            }
            maven { url 'https://maven.fabric.io/public' }
            jcenter()
            google()
        }

注：其中阿里云的速度最快，还有就是不要全部复制
