找不到 ID 为 'com.google.gms:google-services' 的插件。扑

Question

我是 Flutter 框架的新手。我正在尝试在 flutter 中安装 Cloud firestore 但遇到了问题。下面是我的代码和 gradle 文件： Android/build.gradlew:

buildscript {
    // ext.kotlin_version = '1.2.31'
    repositories {
        google()
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath 'com.google.gms:google-services:3.2.0'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

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

App/build.gradle 是：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.barcode_app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    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'
}
apply plugin: 'com.google.gms:google-services'

在运行ning flutter 运行 -v 或在 android 中构建它之后我得到了错误： “错误：找不到 ID 为 'com.google.gms:google-services' 的插件。” enter image description here

我尝试了 Whosebug 和 github 上几乎所有可用的解决方案，但问题仍然存在。

Answer 1

在 app/build.gradle 文件的底部，您有：

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

这实际上应该是：

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

注意 gms 和 google-services 之间的句点，而不是冒号。

编辑： 您遇到这个问题的原因可能是 Google 自己的文档（最后编辑于 3 月 20 日）不正确。我已向他们发送反馈以更正此问题。存档在这里 http://archive.is/4Ujuc

实际上Google是正确的：类路径'com.google.gms:google-services:4.2.0'是正确的，应用插件：'com.google.gms.google-services'也是正确的。一个有冒号，一个有句点。但是名字如此相似，以至于很容易认为它们应该是一样的。请记住 "classpath" - 冒号，"plugin" - 句号。

Answer 2

如果在应用 Jmorris 和 Johnhunter 解决方案后问题仍然存在，请检查此 solution

解决方案是：

Upgrade the Android Gradle plugin to 3.5.0
Upgrade the Google Services plugin to 4.3.3
Upgrade Gradle to 5.4.1 (the required Gradle version for this Android Gradle plugin version)

Answer 3

只需删除 google-services.json 文件并使用您的项目重新配置 firebase。
