Android Studio升级API34时找不到com.android.application:8.5.0插件

使用Android Studio将应用升级到API 34并发布到Google Play商店时，遇到Gradle插件解析错误。

错误信息 #

        file("local.properties").withInputStream { properties.load(it) }
        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
        return flutterSdkPath

解决方法 #

1. 修复插件重复声明问题 #

你的配置中存在插件版本重复声明的冲突：android/settings.gradle已经统一声明了所有插件的版本，app/build.gradle无需再重复指定版本。修改app/build.gradle的plugins块：

plugins {
    id 'com.android.application' apply false
    id 'org.jetbrains.kotlin.android' apply false
    id 'dev.flutter.flutter-gradle-plugin' apply false
    id 'com.google.gms.google-services' apply false
}

2. 清理语法错误 #

app/build.gradle末尾多了一个多余的}，删除该闭合括号，避免语法解析失败。

3. 确保仓库访问正常 #

Android Gradle插件仅发布在Google Maven仓库，你的android/settings.gradle中已经配置了google()仓库，需确保网络可以正常访问该仓库（若有网络限制，需配置代理或镜像）。

4. 清理缓存并重新同步 #

• 执行Android Studio菜单：File -> Invalidate Caches... -> Invalidate and Restart
• 删除项目根目录的.gradle文件夹和android/.gradle文件夹
• 重新执行Gradle Sync操作
