Task :app:uploadCrashlyticsMappingFileRelease FAILED Expected file collection to contain exactly one file, however, it contains no files
Solution 1
Error: "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."
I had something like this in build.gradle
apply plugin: 'com.google.firebase.crashlytics'
apply plugin: 'com.google.gms.google-services'
changed it to this and voila! it works:
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'

I faced the same event today.The reason for this to happen is as follows.
If minify true is set, obfuscation will be applied at build time and mapping.txt will be created.
If minify false, it will not be obfuscated at build time and mapping.txt will not be created.
If you set mappingFileUploadEnabled true in the minify false state, the Firebase SDK will try to upload mapping.txt to Firebase even though mapping.txt is not created at build time. The result is an error.
So, if you set minify false, you have to set mappingFileUploadEnabled false, if you set minify true, you need to set mappingFileUploadEnabled true or false (when mappingFileUploadEnabled false, the crash log on Firebase was obfuscated. It may not make much sense as it will be displayed in state).

I have resolved this issue by moving the following line from bottom of the page to top in build gradle.
Previous Settings:
apply plugin: 'com.google.gms.google-services'
New Settings:
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
apply plugin: 'com.google.firebase.crashlytics'
And the issue is resolved.

In my case I received the error because I wasn't connected to the internet. Fixed it by connecting to the internet and my build release worked perfectly for my Flutter App.
Solution 5
Just change sequence of crashlytics, apply plugin as below :
// Put Google Service
apply plugin: 'com.google.gms.google-services'
// After that the Firebase Crashlytics plugin.
apply plugin: 'com.google.firebase.crashlytics'

I have implemented
Firebase
crashlytics
as suggested. I have put this in my app levelrelease
build variant:firebaseCrashlytics { mappingFileUploadEnabled true }
but when I start to build signed
apk
I am always getting this errorTask :app:uploadCrashlyticsMappingFileRelease FAILED
FAILURE: Build failed with an exception.
- What went wrong: Execution failed for task ':app:uploadCrashlyticsMappingFileRelease'.
Expected file collection to contain exactly one file, however, it contains no files.
If I set
mappingFileUploadEnabled
tofalse
then releaseapk
builds successfully. I have searched a lot but couldn't find a work around. Anyone can help?
