Question

我正在使用Firebase实时数据库。当我想同步gradle时，出现以下错误消息：找不到ID为“ com.google.gsm.google-services”的插件。

我已经下载了google-services.json并将其添加到项目视图中的我的应用程序文件夹中并且我已经尝试了许多类路径，包括：

classpath 'com.google.gms:google-services:4.2.0'
classpath 'com.google.gms:google-services:4.3.1'
classpath 'com.google.gms:google-services:3.0.0'

项目gradle：

{buildscript 
    repositories {
        google()
        jcenter()    
}
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        classpath 'com.google.gms:google-services:4.2.0'
        // 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
}

我的模块应用是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.esppad.friendlychat2"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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.github.bumptech.glide:glide:3.6.1'
    implementation 'com.google.firebase:firebase-database:19.0.0'

}
apply plugin: 'com.google.gsm.google-services'

Answer 1

应用插件：“ com.google.gsm.google-services”不得放置在依赖项中

在如下所示的依赖项之后添加它，

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
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.github.bumptech.glide:glide:3.6.1'
implementation 'com.google.firebase:firebase-database:19.0.0'
}

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

Answer 2

此行中有一个错字：apply plugin: 'com.google.gsm.google-services'应该是gms而不是gsm，如下所示：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.esppad.friendlychat2"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}


dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    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.github.bumptech.glide:glide:3.6.1'
    implementation 'com.google.firebase:firebase-database:19.0.0'
}

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

应用插件错误：“ com.google.gsm.google-services”还添加了类路径“ com.google.gms：google-services：4.2.0”
