Can't start mvnd with noDaemon option

[gboucherie]

Hi,

I try to start running mvnd with the mvnd.noDaemon option set to true but the process failed to start as it's missing the mvnd.java.home property.
For what I understand by reading the code is that this property is normally set by the DaemonConnector class when starting in normal mode.
But with noDaemon mode activated this property is not set before instantiate the Server class and then it fail to find it.

Here is the stacktrace I get.

gboucherie@barret:~$ mvnd.sh -Dmvnd.noDaemon --version

I install mvnd with sdkman and use version 1.0.2.

Could it be a bug or I just missing some configurations.
Thanks

Adding the argument doesn't fix the problem

MVND_CLIENT=jvm mvnd.sh install -N -Dmvnd.noDaemon -Dmvnd.java.home=~/.sdkman/candidates/java/21.0.2-open

[zhaoyunxing92]

It is difficult to reproduce this problem，I tried to modify mvnd.properties and it still works normally,The command line prohibits this parameter
