Uploading ProGuard Mapping Files to Firebase

Question

Am trying out the recently released feature that allows uploading of ProGuard mapping file to Firebase (https://firebase.google.com/docs/crash/android) using gradle task. The following is the task I'm running.

./gradlew -PFirebaseServiceAccountFilePath=xxxxx.json :app:firebaseUploadReleaseProguardMapping

However, it doesn't seem to be recognizing service account file. Has anyone had any luck getting this working? I've also tried defining FirebaseServiceAccountFilePath in gradle.properties.

* What went wrong:
Execution failed for task ':app:firebaseUploadReleaseProguardMapping'.
> Service account file path has not been defined! Service accounts are used to authorize your mapping file uploads.  Learn more at

Answer 1

Set relative path to json in gradle.properties (in project root)

FirebaseServiceAccountFilePath = /firebase-crashreporting.json

and update this property in your build.gradle

apply plugin: 'com.android.application'
apply plugin: 'com.google.firebase.firebase-crash'

android {
    ...
}

setProperty("FirebaseServiceAccountFilePath", rootProject.rootDir.absolutePath + FirebaseServiceAccountFilePath)

dependencies {
    ...
}
