Android 添加firebaseui 2.2.0时出错

我尝试使用firebase ui 2.2.0 这是我的格拉德尔：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support:design:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'

    compile "com.google.android.gms:play-services-auth:11.0.4"
    compile "com.google.firebase:firebase-auth:11.0.4"
    compile "com.google.firebase:firebase-database:11.0.4"
    compile "com.google.firebase:firebase-storage:11.0.4"

    compile 'com.firebaseui:firebase-ui:2.2.0'

    testCompile 'junit:junit:4.12'
}

我犯了以下错误：

Error:Failed to resolve: android.arch.lifecycle:runtime:1.0.0-alpha5
Error:Failed to resolve: com.android.support:customtabs:25.4.0
Error:Failed to resolve: com.android.support.constraint:constraint-layout:1.1.0-beta1
Error:Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha5
Error:Failed to resolve: com.android.support:palette-v7:25.4.0
Error:Failed to resolve: com.android.support:cardview-v7:25.4.0

如何解决这个问题？

我的gradle有什么问题？

确保将Google maven repo添加到顶级gradle文件中。请参阅链接-->

Firebase UI本身具有自己的依赖项集

这些是您的错误日志中说缺少的依赖项

看起来您必须在本地添加这些依赖项才能使FirebaseUI正常工作

事实上，您的错误与FirebaseUI无关。没有这条线，它工作得很好。看起来FirebaseUI将这些作为其依赖项，所以我必须插入FirebaseUI所需的依赖项？不幸的是，看起来是这样的
