Gradle构建错误:不同版本的各种其他库正在请求play-services-ads-base

我检查了一些其他类似的错误,但他们的解决方案都没有解决我的问题.

我无法构建项目,因为我收到了这个确切的错误:

The library com.google.android.gms:play-services-ads-base is being requested by various other libraries at [[17.0.0,17.0.0]], but resolves to 15.0.1. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

首先,我转到依赖树,我看到的所有用途都使用的是版本17.0.0,没有人使用15.0.1.(导致冲突)但是,如果我打开项目依赖项,我会在gradle文件和项目列表之间看到不同的版本.

我已将所有谷歌依赖项更新到最新版本,但它仍然无法正常工作..

如果它没有显示在依赖关系树中,我怎么能弄清楚哪个库正在使用冲突版本？
