android - 添加 firebase 依赖项会导致 gradle 同步失败

Question

我通过 Tools->Firebase->Add Real Time Database 添加了 firebase 数据库依赖项到您的应用程序方法，这导致我的 gradle 同步失败。我猜测依赖项存在冲突(因为我已经使用 firebase 为我的应用程序设置了 google 登录并且一切正常)或者加载了错误的依赖项

implementation 'com.google.firebase:firebase-database:16.0.1:15.0.0'

模块 Gradle 文件:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "nus.is3261.kotlinapp"
        minSdkVersion 21
        targetSdkVersion 28

项目 Gradle 文件:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.2.70'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files

    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }

task clean(type: Delete) {
    delete rootProject.buildDir
