Question

在build.gradle（app）依赖项中：

compile 'com.google.firebase:firebase-database:11.0.4'
compile 'com.google.firebase:firebase-auth:11.0.4'

这是导致失败的行（没有此行，它同步没有任何问题）

compile 'com.firebaseui:firebase-ui-auth:2.1.1'

错误讯息：

Failed to resolve: com.android.support:customtabs:25.4.0
Failed to resolve: com.android.support.constraint:constraint-layout:1.1.0-beta1
Failed to resolve: com.android.support:design:25.4.0
Failed to resolve: com.android.support:cardview-v7:25.4.0

我建议您使用本指南解决firebase-ui-auth依赖性错误：Firebase UI Auth

其次，为了解决项目中com.android.support:的依赖性错误，

转到项目级别 build.gradle ＆amp;检查它是否完全像这样：

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

添加FirebaseUI依赖项后同步失败
