The issue is observed only with the new versions of crashlytics-gradle plugin (v2.5.0 and v2.5.1). It works as expected with older plugin versions (e.g. 2.4.1).

Expected behavior: task ‘uploadCrashlyticsSymbolFile[BuildVariant]’ generates and uploads native symbols to crashlytics servers.

Steps to reproduce:

• Create a new template project “Native C++”
• Add Firebase analytics, crashlytics, crashlytics-ndk (using Assistant or manually),
• Add google-services.json (create/connect to a Firebase project)
• Set crashlytics gradle plugin version to firebase-crashlytics-gradle:2.5.0 (or 2.5.1)
• Add the following to a relevant build variant (or to defaultConfig):

            firebaseCrashlytics {
                    nativeSymbolUploadEnabled true
            }

• build project
• run task ‘generateCrashlyticsSymbolFile[BuildVariant]’ or ‘uploadCrashlyticsSymbolFile[BuildVariant]’
• the task will fail with

		Task generateCrashlyticsSymbolFile<BuildVariant> fails with exception:
			
		Execution failed for task ':app:generateCrashlyticsSymbolFile<BuildVariant>'.
		> java.io.IOException: The filename, directory name, or volume label syntax is incorrect

It seems there is a bug in firebase-crashlytics-gradle plugin. Wondering if you guys are doing any QA testing before releasing updates?

Confirmed - it works fine with v2.5.2 - thank you!

[mrichards]

v2.5.2 of the Crashlytics plugin was released last Thursday and should resolve the issue. Please let us know if your problem persists!
