Review Comment:
I wouldn't recommend using maven on a share, it would be not the fastest
experience. 😉

> Native support for PowerShell to start Maven
> --------------------------------------------
>
> Key: MNG-7541
> URL: https://issues.apache.org/jira/browse/MNG-7541
> Project: Maven
> Issue Type: Improvement
> Components: Command Line
> Affects Versions: 3.8.3
> Environment: windows 10 / 11
> Reporter: Jurrian Fahner
> Priority: Trivial
> Labels: Script, Windows10, Windows11
>
> Maven has two files in the bin dir:
> ||command||its use||
> |mvn|POSIX shell|
> |mvn.cmd|cmd.exe|
> On windows there are two ways to write scripts, by using cmd.exe or using
> powershell.
> If you enter mvn in powershell it will look for `mvn.ps1` on the PATH first.
> If it doesn't find anything it will execute `mvn.cmd` as fall-back.
> When running maven for starting a server for development purposes and you do
> ctrl-c to exit the server it will ask the question: Terminate batch job (Y/N)?
> As far as I know it is default behaviour of cmd.exe.
> Well if I don't want to terminate, I wouldn't press ctrl-c. ;)
> It is not the case (as far as I know that Microsoft is going to deprecate
> cmd.exe in favor of powershell:
> [https://devblogs.microsoft.com/commandline/rumors-of-cmds-death-have-been-greatly-exaggerated/]
> Allthough I think it would be a good move for maven to have also a powershell
> script as well... It is possible to integrate elegant support for native help
> in powershell, `get-help mvn`.
> But it also increases the maintenance effort as well. I don't know whether
> this cost outweigh the benefits, though...
> By the way I would happy to contribute if it is appreciated.
