Nextcloud dev: Failed to find any output apks

Hi, according to build log (https://f-droid.org/wiki/index.php?title=com.nextcloud.android.beta/lastbuild_20170816&redirect=no):

ERROR: Could not build app com.nextcloud.android.beta: Failed to find any output apks

The reason is that now the output apk is in: build/outputs/apk/generic/release/

Previous it was in: build/outputs/apk/

I think this is related to using the newest gradle-4.1, so this might happen also on other packages and should be fixed on fdroid side?

Best regards, Tobias
