Command line -version switch

Please could the 3.x version of GanttProject have the -version command line switch again, like the 2.x version did?

prompt>ganttproject.exe -version

Interestingly I notice that the version switch seems to only work with the ganttproject.bat rather than also with the ganttproject.exe for version 2.8.11, I don’t know why. For 3.0.3002 it seems that the ganttproject.bat just hangs whether or not I give it the -version switch.

For both 2.8 and 3.0 ganttproject.exe -version seems to do nothing, and returns you to a prompt without running the program.

I am using zulu java 11 on Windows (8.1 and 10).
