I found the solution for Windows in past conversations. I post it here just in case if someone needed it
- Remove/comment the gauge_report_dir value set in the default.properties file. (Important!)
- set gauge_report_dir=<your directory> as environment variable, and run gauge specs
set datestr=%date:~-4,4%%date:~3,2%%date:~-10,2%%time:~0,2%%time:~3,2% && set gauge_reports_dir=C:\Jenkins\workspace\Tests\%datestr% && gauge run specs
