Android Studio Koala Canary5升级AGP后出现Google Services同步错误

问题概述 #

升级到Android Studio Koala（2024.1.1 Canary 5）后，按提示将Android Gradle Plugin（AGP）更新至8.5.0-alpha05，出现以下错误：

Querying the mapped value of flatmap(provider(task 'processDebugGoogleServices', class com.google.gms.googleservices.GoogleServicesTask)) before task ':app:processDebugGoogleServices' has completed is not supported

已使用最新版本的Google Services插件（4.4.1），但在Canary 4版本中可正常运行。

Google Services插件配置：

googleServices = { id = "com.google.gms.google-services", version.ref = "googleServices" }

可能的解决方法 #

• 调整插件应用顺序：确保Google Services插件在所有代码生成类插件（如KSP、Room等）之后应用，将id("com.google.gms.google-services")移至模块build.gradle.kts的插件列表末尾。
• 延迟配置避免提前查询：如果有自定义任务依赖processDebugGoogleServices的输出，改用Gradle的provider或延迟属性获取值，避免在任务执行前查询结果。示例：

  val googleServicesOutput = tasks.named("processDebugGoogleServices").map { it.outputs.files.singleFile }
  // 在依赖任务中通过googleServicesOutput.get()获取，确保任务依赖已正确声明
  

• 尝试预览版插件：检查是否有适配AGP 8.5的Google Services预览版本，替换版本号为对应预览版（如4.4.2-alpha01）测试兼容性。
• 临时回退AS版本：若上述方法无效，暂时回到Android Studio Koala Canary 4，等待插件或AGP修复该兼容性问题。
