Gradle中的依赖关系失败基于我应用程序中没有的依赖关系

Question

当我将implementation 'com.google.firebase:firebase-admin:6.8.1'添加到我的依赖项时，我的构建失败：

In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[1.12.
0]", but isn't being resolved to that version. Behavior exhibited by the library will be unknown.

Dependency failing: io.grpc:grpc-okhttp:1.12.0 -> io.grpc:grpc-core@[1.12.0], but grpc-core version was 1.13.1.

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends onto io.grpc:grpc-stub@{strictly 1.13.1}
-- Project 'app' depends onto io.grpc:grpc-okhttp@{strictly 1.12.0}
-- Project 'app' depends onto com.google.cloud:google-cloud-core-grpc@{strictly 1.43.0}
-- Project 'app' depends onto io.grpc:grpc-auth@{strictly 1.13.1}
-- Project 'app' depends onto io.grpc:grpc-protobuf@{strictly 1.13.1}
-- Project 'app' depends onto io.grpc:grpc-protobuf-lite@{strictly 1.13.1}
-- Project 'app' depends onto com.google.firebase:firebase-admin@6.8.1
-- Project 'app' depends onto com.google.firebase:firebase-firestore@{strictly 17.1.2}
-- Project 'app' depends onto com.google.firebase:firebase-firestore@17.1.2
-- Project 'app' depends onto io.grpc:grpc-core@{strictly 1.13.1}
-- Project 'app' depends onto com.google.cloud:google-cloud-firestore@{strictly 0.61.0-beta}
-- Project 'app' depends onto com.google.firebase:firebase-admin@{strictly 6.8.1}
-- Project 'app' depends onto io.opencensus:opencensus-contrib-grpc-util@{strictly 0.15.0}
-- Project 'app' depends onto com.google.api:gax-grpc@{strictly 1.30.0}

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 b
uild.gradle file.

但是我的gradle中没有任何okhttp / grpc依赖项：

build.gradle（项目）

buildscript {

    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }
}

我已经搜索了整个项目目录，并且关键字grpc和okhttp不存在。但是我确实在Android SDK代码中找到了实例：

这是否意味着构建工作的唯一方法是添加grpc / okhttp依赖项？这似乎不正确，因为Add the Firebase Admin SDK设置中没有提及此内容。
