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

Question

我是Flutter框架的新手。我试图在扑扑中安装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'

运行flutter运行-v或在android中构建它后，出现错误： '错误：找不到ID为'com.google.gms：google-services'的插件。 enter image description here

我试图在stackoverflow和github上提供几乎所有可用的解决方案，但是问题仍然存在。

Answer 1

在您的app / build.gradle文件的底部，您拥有：

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

这实际上应该是：

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

请注意gms和google-services之间的时间段，而不是冒号。

编辑：您可能会遇到此问题，因为Google自己的文档（最新编辑于3月20日）不正确。我已向他们发送了反馈，以纠正此问题。  存档在这里http://archive.is/4Ujuc

Answer 2

如果应用 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 #include<fplus/maps.hpp> // ... int main() { map<string, int32_t> myMap{{"a", 1}, {"b", 2}}; vector<string> keys = fplus::get_map_keys(myMap); // ... return 0; } 文件并使用您的项目重新配置 Firebase。
