Description

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:

🕙 15:01:32 ➜ mvn --version

user.name=test

In Maven 4.0.0-SNAPSHOT the behavior is different:

🕙 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 identify it.
