Kotlin 找不到 androidsdk.modules

因此，在运行我的程序的过程中，我的build.gradle失败，并显示以下错误.我的意思是，它实际上是在一秒之前起作用的，而不是在一秒之后.我的答卷什么也没改.

Could not find androidsdk.modules:shield:unspecified.
Required by:
    project :app > com.facebook.android:facebook-login:5.15.2
    project :app > com.facebook.android:facebook-core:5.15.2
    project :app > com.facebook.android:facebook-common:5.15.2
Search in build.gradle files

这是我的格拉德尔.

我不知道这是怎么发生的也不知道为什么.恢复到之前有效的git回购不会改变任何事情.可能是什么问题呢？
