Our project uses a lot of native libraries (3rd party and our own), and from the stack trace it seems like the issue might be related to one of these libraries. However I’ve been unable to track down which library is causing this. Any further insights or help debugging this would be appreciated.

Steps to reproduce:

Run above command.

StackOverflow question with what looks like the same issue:
https://stackoverflow.com/q/60259789/1534401

[vokilam]

https://github.com/firebase/firebase-android-sdk/issues/1396 similar issue with example repository

[personshelldon]

#1298, the same problem here. Did You find any solution?

[triplef]

No solution yet, but Firebase support said they are looking into it.

I am not using Gradle KTS tho. Is your stack trace the same as this one (see "Full output with --stacktrace" above)?

[personshelldon]

@triplef, yes, it the same. If I'm using KTS, the task uploadCrashlyticsSymbolFile{flavor} is not even generated. Without KTS - the error is the same as Yours.

[triplef]

Sounds like you’re running into two separate issues then.

It might help to also reach out to Firebase support via email to see if they can use any further info.

[triplef]

I just tested it again using the following latest Crashlytics releases but the issue persists:

• com.google.firebase:firebase-crashlytics-gradle:2.0.0-beta04
• com.google.firebase:firebase-crashlytics:17.0.0-beta04
• com.google.firebase:firebase-crashlytics-ndk:17.0.0-beta04

Hey everyone! Wanted to circle back here and let you know the issue has been fixed, and the fix will be available in the next Crashlytics Gradle plugin release.

[mrwillis21]

Duplicate of #1396

[mrwillis21]

Turns out this is a separate issue from #1396, which has been fixed in Crashlytics Gradle Plugin 2.1.0. Re-opening this to track it separately.

[mrwillis21]

Hi @triplef - just wanted to circle back and let you know I've got a fix in the works for this, which I plan to get in for the next release. Thanks so much for the information you provided that helped us reproduce the issue!

[triplef]

That’s great. Thank you for the update on this!

[mrwillis21]

Hi @triplef - wanted to let you know the Crashlytics Gradle plugin version 2.1.1 has been released which should fix the issue you were seeing. Please do let me know if you run into any other problems!

[triplef]

Awesome, I can confirm it is no longer crashing. Thank you!
