尝试在AndroidStudio中添加Firebase依赖项时出现重复类错误

Question

我正在尝试在AndroidStudio中开发一个应用，并且正在将Cloud Firestore用作数据库。当我尝试同时添加'com.google.firebase:firebase-admin:6.11.0'和'com.google.firebase:firebase-core:17.0.0依赖项时遇到一些问题。当我尝试创建项目时，我收到以下消息：

Duplicate class com.google.firebase.FirebaseAppLifecycleListener found in modules firebase-admin-6.11.0.jar (com.google.firebase:firebase-admin:6.11.0) and firebase-common-18.0.0-runtime.jar (com.google.firebase:firebase-common:18.0.0)

Go to the documentation to learn how to Fix dependency resolution errors.

我尝试了其他一些版本，较旧和较新，但遇到了相同的问题。有人知道如何解决吗？非常感谢。这是我的应用程式Gradle代码

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.2"
    defaultConfig {
        applicationId "br.com.valorinveste.nextmobilefx"
        minSdkVersion 16
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        packagingOptions {
            exclude 'META-INF/INDEX.LIST'
            exclude 'META-INF/DEPENDENCIES'
            exclude 'META-INF/io.netty.versions.properties'
        }
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'androidx.appcompat:appcompat:1.1.0'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
//    implementation 'com.google.firebase:firebase-analytics:17.0.0'
    implementation 'com.google.firebase:firebase-admin:6.11.0'
    implementation 'com.google.firebase:firebase-core:17.0.0'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.2.0'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

和项目gradle代码

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.3'
        classpath 'com.google.gms:google-services:4.3.3'
        // 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
}
