firebase - 类型 'UploadMappingFileTask' 属性 'googleServicesResourceRoot' 没有配置值

Question

更新类路径后，我无法再构建应用程序的发布版本。

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':app:uploadCrashlyticsMappingFileRelease' (type 'UploadMappingFileTask').
  - Type 'UploadMappingFileTask' property 'googleServicesResourceRoot' doesn't have a configured value.
    
    Reason: This property isn't marked as optional and no value has been configured.
    
    Possible solutions:
      1. Assign a value to 'googleServicesResourceRoot'.
      2. Mark property 'googleServicesResourceRoot' as optional.



    A problem was found with the configuration of task ':app:uploadCrashlyticsMappingFileRelease' (type 'UploadMappingFileTask').

我试图阅读变更日志，但没有关于它的指南或文档。

要修复它，应该在 /app/build.gradle 中的任何 Firebase 插件之前应用 Google 服务插件.
这会产生错误

apply plugin: 'com.android.application'
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.firebase-perf'

虽然这不
请注意 com.google.gms.google-services是 上图 com.google.firebase.crashlytics

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'com.google.firebase.firebase-perf

当您更新到 com.google.firebase:firebase-crashlytics-gradle:2.7.0 并同步更改时，您会收到一条消息，说明已修复。

Configure project :app
Crashlytics could not find Google Services plugin task: processReleaseGoogleServices. Make sure com.google.gms.google-services is applied BEFORE com.google.firebase.crashlytics. If you are not using the Google Services plugin, you must explicitly declare `googleServicesResourceRoot` inputs for Crashlytics upload tasks.
