Java 错误：在项目中'；app&x27；已解决的Google Play服务库依赖关系取决于另一个精确版本

我在打开android studio的旧应用程序时遇到一些错误

ERROR: In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0.1]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Dependency failing: com.google.android.gms:play-services-flags:15.0.1 -> com.google.android.gms:play-services-basement@[15.0.1], but play-services-basement version was 16.0.1.

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your build.gradle file.
