Question

我已经在Android Studio中创建了一个Firestore项目。我在其中实施了Firebase授权，并且工作正常。我可以将文档推送到Firestore数据库。

但是现在，我试图添加一些功能，通过这些功能可以将媒体/图像存储到Firebase Storage，但是当我将此依赖项添加到应用程序的build.gradle文件中时，却出现此错误：

添加了依赖性：

implementation 'com.google.firebase:firebase-storage:16.0.1'

这是我得到的错误：

Could not find firebase-common.jar (com.google.firebase:firebase-common:16.0.0).
Searched in the following locations:https://jcenter.bintray.com/com/google/firebase/firebase-common/16.0.0/firebase-common-16.0.0.jar

仅供参考，在我的项目中，我已经有这种配置：

classpath 'com.android.tools.build:gradle:3.1.3'

和

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

当我仅将firebase-storage依赖项添加到我的Android项目中时，我找不到问题所在。

这是我的应用程序级别的build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '27.0.3'

    defaultConfig {
        applicationId "com.firebase.example"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
}

dependencies {
    implementation 'com.google.firebase:firebase-firestore:16.0.0'
    implementation 'com.google.firebase:firebase-auth:15.1.0'
    implementation 'com.google.firebase:firebase-storage:16.0.1'

    implementation 'com.google.android.gms:play-services-auth:15.0.1'

    implementation fileTree(dir: 'libs', include: ['*.jar'])
    testImplementation 'junit:junit:4.12'
    implementation 'com.android.support:appcompat-v7:23.2.1'
    implementation 'com.android.support:design:23.2.1'
    implementation 'com.android.support:recyclerview-v7:23.2.1'
}
apply plugin: 'com.google.gms.google-services'

这是我的模块级别的build.gradle文件：

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

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1' // google-services plugin
        classpath 'com.google.android.gms:play-services-base:15.0.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        google()
    }
}

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

Answer 1

您是否已将它们添加到根级别gradle文件中？

buildscript {

    dependencies {

        classpath 'com.google.gms:google-services:4.0.1' 
    }
}

allprojects {

    repositories {

        google() 
    }
}

Answer 2

您必须在根级别的build.gradle文件中添加dependencies {classpath 'com.google.gms:google-services:4.0.1'}和repositories { google()}。你加了吗？此外，请提供整个build.gradle文件，以了解您的问题。

Answer 3

升级以下内容：

 implementation 'com.google.firebase:firebase-firestore:16.0.0'
 implementation 'com.google.firebase:firebase-auth:15.1.0'

对此：

 implementation 'com.google.firebase:firebase-firestore:17.0.2'
 implementation 'com.google.firebase:firebase-auth:16.0.2'

Answer 5

我能够使它工作。您可以简单地比较我的新gradle文件。问题是Google服务库和Gradle版本冲突。因此，我创建了一个新项目，并再次像这样添加了依赖项，它就起作用了。

因此，我从app / build.gradle中删除了它：

implementation 'com.google.android.gms:play-services-auth:15.0.1'

然后，将其从module / build.gradle中删除：

classpath 'com.google.android.gms:play-services-base:15.0.1'

，并在module / build.gradle中更新了gradle版本：

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

新的build.gradle文件如下所示。

module / build.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:3.1.3'
        classpath 'com.google.gms:google-services:4.0.1' // google-services plugin

        // 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
}

app / build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "master.firebasesetup"
        minSdkVersion 15
        targetSdkVersion 27
        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 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support:support-v4:27.1.1'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

    implementation 'com.google.firebase:firebase-firestore:17.0.2'
    implementation 'com.google.firebase:firebase-auth:16.0.2'
    implementation 'com.google.firebase:firebase-storage:16.0.1'
    implementation 'com.google.firebase:firebase-core:16.0.1'
}
apply plugin: 'com.google.gms.google-services'

错误：在将Firebase Storage依赖项添加到Android Studio Project中？
