配置Firebase时出现Could not find com.google.gms.google-services错误求助

错误信息 #

The supplied phased action failed with an exception. A problem occurred configuring root project 'android'. Could not resolve all files for configuration ':classpath'. Could not find com.google.gms.google-services:4.3.15:. Required by: project :

问题原因 #

com.google.gms.google-services:4.3.15版本已不再被官方仓库收录，且与当前使用的Gradle 7.2.0版本存在兼容性问题，导致Gradle无法解析该依赖包。

修复步骤 #

1. 将google-services插件版本升级至与Gradle 7.2.0兼容的稳定版本（如4.4.0）
2. 确认buildscript的仓库配置包含google()和mavenCentral()，确保依赖可正常拉取

修改后的android/build.gradle #

buildscript {
    ext.kotlin_version = '1.7.10'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.2.0'
        // 替换为兼容的google-services版本
        classpath "com.google.gms.google-services:4.4.0"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

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

android/app/build.gradle（保持现有配置即可） #

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'
}

额外操作 #

• 执行flutter clean清理缓存
• 执行flutter pub get拉取最新依赖
• 重新运行项目构建
