Question

我已更新firebase-auth依赖版本，但gradle构建始终失败。它适用于16.0.1

错误Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.google.firebase:firebase-auth:16.0.2.

app level gradle file

apply plugin: 'com.android.application'
android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.example.dell.pitchpls"
        minSdkVersion 21
        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'
        }
    }
    buildToolsVersion '27.0.3'

}

    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

项目级别gradle文件

    // 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:3.1.0'
        classpath 'com.google.gms:google-services:4.0.1'

        // 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
}

Answer 1

问题在this问题后得到解决。只需取消选中设置/ gradle中的离线工作

Answer 2

尝试以下步骤：

打开应用程序的模块设置
在“依赖关系”选项卡下，单击“+”符号并手动添加依赖关系
点击“应用”。

Answer 3

Firebase Documentation

如果您访问此链接并向下滚动以添加依赖项部分，则会发现gradle依赖项版本仅为 16.0.1

此外，为避免此类错误，请让Android Studio自动为您完成操作。

为此，请在Android Studio中转到：工具-> Firebase（这将打开一个Firebase助手）

现在选择您的类别，例如身份验证，分析，云消息传递等->单击“设置您的类别”，然后继续执行此处提到的步骤。它将自动添加所有gradle文件和生成的JSON文件。
