ODK Briefcase 1.9 - Where is the log file stored?

What is the problem? Please be detailed.

I am not able to get the briefcase log file. I also customized the CLI script to generate log files but the are all empty. The script generated log files with earlier versions on ODK Briefcase.

What ODK tool and version are you using? And on what device and operating system version?

ODK Briefcase 1.9
Java 8 (looks like Java 9 doesn't exist)

What steps can we take to reproduce the problem?

I run ODK Briefcase on CLI using scripts

What you have you tried to fix the problem?

Customised the script to generate a log file

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.
None at the moment. The log files generated by the CLI script are blank

The error log was added in v1.11, so you'll need up upgrade to the latest version. https://github.com/opendatakit/briefcase/releases/latest
