Android Google Map 和 firebase 依赖问题

Question

我第一次与 firebase 一起处理 map ，并且遇到了依赖性问题。

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 16.0.1.

然而，在更新 SO(为了避免版本冲突)上的其余问题之后

implementation 'com.google.android.gms:play-services-maps:16.0.0'

到

implementation 'com.google.android.gms:play-services-maps:16.0.1'

不适合我。 同样，更新

implementation 'com.google.firebase:firebase-auth:16.0.1' implementation 'com.google.firebase:firebase-database:16.0.1'

到

implementation 'com.google.firebase:firebase-auth:16.0.0' implementation 'com.google.firebase:firebase-database:16.0.0'

也不行。这两种情况都给出了相同的错误，即依赖项不存在。 除了这些，我还尝试过清理和重建项目，但这也不起作用。请帮我解决这个问题

    apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

经过更多的依赖组合，转换为以下 3 行

implementation 'com.google.firebase:firebase-auth:16.0.1'
implementation 'com.google.firebase:firebase-database:16.0.1'
implementation 'com.google.android.gms:play-services-maps:16.0.0'

到

implementation 'com.google.firebase:firebase-auth:15.0.0'
implementation 'com.google.firebase:firebase-database:15.0.0'
implementation 'com.google.android.gms:play-services-maps:15.0.0'

为我工作。
