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').

我试图阅读更新日志，但没有任何指南或文档。

Answer 1

要解决此问题，应在 /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'

虽然不是这样：

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

请注意，com.google.gms.google-services 高于 com.google.firebase.crashlytics。

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，说明修复如下：

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.

Answer 2

确定

'com.google.gms.google-services'

在之前应用：

'com.google.firebase.crashlytics'

为我修复了错误。

Answer 3

我也没有找到任何东西，现在将 firebase-crashlytics-gradle 更改为 2.6.1 似乎没问题。

Answer 4

我的项目没有使用'com.google.gms.google-services'。您需要将'com.google.gms.google-services'添加到插件中的应用级Gradle文件中，并在项目级Gradle文件中添加其对应的类路径依赖classpath 'com.google.gms:google-services:latest-version'。

如其他答案所述，还要确保 com.google.gms.google-services 出现在 com.google.firebase.crashlytics 之前。
