After updating the classpath I can no longer build a release version of the app.
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').
- Type 'UploadMappingFileTask' property 'googleServicesResourceRoot' doesn't have a configured value.
I tried to read the changelog but no guidelines or documentation about it.
To fix it, the Google Services plugin should be applied before any Firebase plugin in /app/build.gradle.
This produces the error:
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'
While this does not:
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
Note that com.google.gms.google-services is ABOVE com.google.firebase.crashlytics.
When you update to com.google.firebase:firebase-crashlytics-gradle:2.7.0 and sync the changes, you are given a message stating that is the fix as follows:
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.
