Hello, when running vadere-console.jar with any subcommand (e.g. project-run) with the --help flag, the following message appears:

usage: Vadere project-run [-h] --project-dir PROJECT-DIR [--scenario-checker {on,off}]

optional arguments:
  -h, --help             show this help message and exit
  --project-dir PROJECT-DIR, -p PROJECT-DIR
                         Path to project directory.
  --scenario-checker {on,off}
                         Turn Scenario Checker on or off.

Note that --project-dir is listed under optional arguments.

However, when running project-run without any arguments, the following error message appears:

usage: Vadere project-run [-h] --project-dir PROJECT-DIR [--scenario-checker {on,off}]
Vadere: error: argument --project-dir/-p is required

Obviously, this behavior is confusing and the --project-dir argument should be listed under required arguments (or just be passed as an required positional argument).
