---------------------------------------------------------------
Fwiw, those properties are of type {{java.nio.file.Path}} which may not play
well with maven 3 plugins or alike which only supports {{{}File{}}}. A
workaround is to use {{[the-prop].file}} instead.

> This issue introduces three properties:
> * {{project.rootDirectory}}: {_}the project's directory or parent directory
> containing a {{.mvn}} subdirectory or a {{pom.xml}} flagged with the
> {{root="true"}} attribute{_}. If no such directory can be found, accessing
> the rootDirectory property will throw an `IllegalStateException`.
> * {{session.topDirectory}} : {_}the directory of the topmost project being
> built, usually the current directory or the directory pointed at by the
> {{\-f}}/{{\-\-file}} command line argument{_}. The {{topDirectory}} is
> similar to the {{executionRootDirectory}} property available on the session,
> but renamed to make it coherent with the new {{rootDirectory}} and to avoid
> using _root_ in its name. The {{topDirectory}} property is computed by the
> CLI as the directory pointed at by the {{\-f}}/{{\-\-file}} command line
> argument, or the current directory if there's no such argument.
> * {{session.rootDirectory}} : {_}the rootDirectory for the topDirectory
> project{_}.
> The {{topDirectory}} and {{rootDirectory}} properties are made available on
> the {{MavenSession}} / {{Session}} and deprecate the
> {{executionRootDirectory}} and {{multiModuleProjectDirectory}} properties.
> The {{rootDirectory}} should never change for a given project and is thus
> made available for profile activation and model interpolation (without the
> {{project.}} prefix, similar to {{basedir}}). The goal is also to make the
> {{rootDirectory}} property also available during [command line arguments
> interpolation|https://issues.apache.org/jira/browse/MNG-6303].
> A {{root}} boolean attribute is also added to the model to indicate that the
> project is the root project. This attribute is only supported if the
> _buildconsumer_ feature is active and removed before the pom is installed or
> deployed. It can be used as an alternative mechanism to the {{.mvn}}
> directory.
