【中文标题】Flutter Firebase 插件问题：不兼容问题【英文标题】：Flutter Firebase Plugin Issues: Incompatibility issues 【发布时间】：2020-04-01 03:06:33 【问题描述】：

在我将 firebase 插件添加到我的颤振项目后，出现以下错误： ProcessException：进程“C:\projects\ecommerce\android\gradlew.bat”异常退出：启动 Gradle 守护进程（后续构建会更快）

FAILURE：构建失败并出现异常。 * 在哪里：构建文件 'C:\projects\ecommerce\android\app\build.gradle' 行：24 * 什么地方出了错：评估项目 ':app' 时出现问题。

无法应用插件 [id 'com.android.application'] 支持的最低 Gradle 版本为 5.4.1。当前版本是 4.10.2。如果使用 gradle 包装器，请尝试编辑 C:\projects\ecommerce\android\gradle\wrapper\gradle-wrapper.properties 中的 distributionUrl 到 gradle-5.4.1-all.zip。

这是我的 android\app\build.gradle。

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 plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android 
    compileSdkVersion 28

    sourceSets 
        main.java.srcDirs += 'src/main/kotlin'
    

    lintOptions 
        disable 'InvalidPackage'
    

    defaultConfig 
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.ecommerce"
        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 '../..'

    implementation 'com.google.firebase:firebase-analytics:17.2.0'


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

这是我的 android\build.gradle：

rootProject.buildDir = '../build'
subprojects 
    project.buildDir = "$rootProject.buildDir/$project.name"



//      ====SUBPROJECT DEPENDENCIES START HERE

                details.useVersion "1.0.1"
            
        
    
  
//ENDS HERE

task clean(type: Delete) 
    delete rootProject.buildDir

C:\Program Files\Android\Android Studio\gradle中的gradle版本：是5.1.1。我的 android\build.gradle 中的 gradle 版本，依赖：

dependencies 

        classpath 'com.android.tools.build:gradle:3.5.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.2'
    ```

I dont know if there's any conflict between 
```classpath 'com.google.gms:google-services:4.3.2' ```
with:
```classpath 'com.android.tools.build:gradle:3.5.2'```

Please help

这些是我在最近一次演示中使用的链接。它们包含截至 3 周前所有内容的必要版本。试一试。

所以，在整个互联网上梳理了两天后，我终于通过更改 classpath 'com.google.gms:google-services:4.3.2' 至，classpath 'com.google.gms:google-services:4.2.0'

另外，在 android/build.gradle 文件中升级我的 gradle 依赖项：来自：

classpath 'com.android.tools.build:gradle:3.2.1'
