Hi!

I've noticed the regression in the latest Maven 4.0-SNAPSHOT. System properties 
are no longer overridden with user properties with the same name.

In Maven 3.9.2 and earlier properties set via the command line 
({_}-Duser.name=test{_}) where overriding system properties with the same name:

{code:java}

In Maven 4.0.0-SNAPSHOT the behavior is different:

{code:java}
🕙 15:08:23 ➜ ./mvn --version
Unable to find the root directory. Create a .mvn directory in the root 
directory or add the root="true" attribute on the root project's model to
