It seems as if today is not my day. First, I wrote a message in another thread with tons of typos, making it look as if I am not just bad in typing but actually unable to speak proper English. Now, I sent an incomplete message not addressing the actual question. Sorry for that to everyone.
Let us settle on only using double quotes to enclose arguments containing spaces. Then, we do not need to escape single quotes and can use them literally. But we do need to escape nested double quotes. In UNIX-like shells like Bash, a double quote is escaped by a backslash: -Dexec.args="one \"it's OK\" three" In Windows Cmd.exe, a double quote is escaped by another double quote: -Dexec.args="one ""it's OK"" three" HTH -- Alexander Kriegisch https://scrum-master.de Alexander Kriegisch schrieb am 15.10.2023 11:17 (GMT +07:00): > 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.
