Java CLI program arguments containing spaces are usually enclosed by double quotes, so I would recommend to use:
-Dexec.args="one 'number two' three" This works in both UNIX-like shells (say, Git Bash on Windows) and in the Cmd.exe Windows shell, while -Dexec.args='one "number two" three' only works in UNIX-like shells, but *not* in Cmd.exe. -- Alexander Kriegisch https://scrum-master.de Garret Wilson schrieb am 15.10.2023 05:31 (GMT +07:00): > Here's a fun one for your weekend.
