Jeff Pierson commented on MNG-7131:
-----------------------------------
[~michael-o], ok so this is an expected breaking change? I couldn't find much
details in documentation or other discussion other than the change to put
arguments on separate lines. Is the workaround that I found the preferred one
because like the original poster I did try quoting the argument value such as
below which also didn't work.
-s ".mvn/settings.xml"
and
"-s .mvn/settings.xml"
At the same time I see that this issue which is about the allowing spaces with
quoting behavior is marked fixed in previous versions. So I'm now wondering
that if {{-s .mvn/settings.xml}} is not a regression from Maven 3 and an
intentional breaking change on whether my attempt to quote the value as {{"-s
.mvn/settings.xml"}} is a regression somewhere in the Maven 4 Alphas. Is there
somewhere that explains this behavior and the breaking changes so that I can
plan next steps for my projects which will adopt Maven 4 or help to open a new
issue?

> I tried putting a path with a space in the maven.config like so:
> {code:java}
> "-Dmy.path=/some/path with/a/space"
> {code}
> When asking for the my.path property inside Maven, I get the path with a
> trailing quote
> {code:java}
> /some/path with/a/space"
> {code}

> I suggest replacing that code with the much better
