将Firebase添加到我的依赖项“程序已存在”后出现错误

Question

最近在将Firebase添加到我的代码中后，显示“程序类型已存在” 全栈： 错误：程序类型已经存在：com.firebase.client.android.AndroidCredentialStore

build.gradle应用程序：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.user.candleclub"
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

项目gradle：

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

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        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
}

manifest.xml：

            </intent-filter>
        </activity>
        <activity android:name=".MainActivity" />
    </application>

</manifest>

试图添加各种依赖关系，但并没有解决。有人有主意吗？

编辑：注释掉所有Firebase依赖项后，没有错误。有人知道为什么吗？有没有办法使用Firebase的存储而不会出现错误？
