这是我的应用程序模块

 apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-android-extensions' android { compileSdkVersion 26 defaultConfig { applicationId "appname" minSdkVersion 15 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support:animated-vector-drawable:26.1.0' implementation 'com.android.support:mediarouter-v7:26.1.0' implementation 'com.android.support.constraint:constraint-layout:1.0.2' implementation 'com.android.support:appcompat-v7:26.1.0' implementation 'com.android.support:recyclerview-v7:26.1.0' implementation 'com.android.support:cardview-v7:26.1.0' implementation 'com.android.support:design:26.1.0' implementation 'com.firebaseui:firebase-ui-database:3.0.0' //noinspection GradleCompatible,GradleCompatible implementation 'com.google.android.gms:play-services:11.0.4' implementation 'com.google.firebase:firebase-auth:11.0.4' implementation 'com.google.firebase:firebase-database:11.0.4' implementation 'com.google.firebase:firebase-storage:11.0.4' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.1' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1' compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" } repositories { mavenCentral() } apply plugin: 'com.google.gms.google-services' 

我的项目gradle是这样的

 // Top-level build file where you can add configuration options common to all sub-projects/modules. buildscript { ext.kotlin_version = '1.1.51' repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.0.1' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files classpath 'com.google.gms:google-services:3.1.0' } } allprojects { repositories { google() jcenter() maven { url "https://jitpack.io" } } } task clean(type: Delete) { delete rootProject.buildDir } 

我有firebase.auth implemetation但它仍然显示我的错误。

我在你的gradle文件中看到至少2个问题:

  1. 你有一个“kotlin-stdlib-jre7”的重复条目(一个实现和一个编译)。 删除最后一个:

     compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version" 
  2. 不使用最新版本的Firebase和Google Play服务:更新到Firebase 11.6.2
