google 的 maven 仓库是不支持浏览的，如果你需要下载特定一个库，可以自行拼接这样的地址 
https://dl.google.com/dl/android/maven2/com/android/databinding/compiler/3.0.1/compiler-3.0.1-sources.jar 来进行下载

    repositories {
        // maven库
        def aliMaven = "http://maven.aliyun.com/nexus/content/groups/public/"
        def cMaven = "https://repo1.maven.org/maven2"
        // 先从url中下载jar若没有找到，则在artifactUrls中寻找
        maven {
            url aliMaven
            artifactUrls cMaven
        }
    }
