> I have setup a project which uses the following parts 
> (https://maven.apache.org/docs/3.9.2/release-notes.html)
> * {{${session.topDirectory}}} 
> * {{${session.rootDirectory}}} 
> * {{${project.rootDirectory}}} 
> but unfortately they are not being replaced during the run of the project... 
> A small excerpt from the project... using the following simple configuration:
> {code:xml}
>       <plugin>
>         <groupId>com.soebes.maven.plugins</groupId>
>         <artifactId>echo-maven-plugin</artifactId>
>         <version>0.5.0</version>
>         <executions>
>           <execution>
>             <phase>initialize</phase>
>             <goals>
>               <goal>echo</goal>
>             </goals>
>             <configuration>
>               <echos>
> </echo>
>                 <echo>project.rootDirectory: '${project.rootDirectory}'</echo>
>                 <echo>session.rootDirectory: '${session.rootDirectory}'</echo>
>                 <echo>session.topDirectory: '${session.topDirectory}'</echo>
>                 <echo>project.basedir: '${project.basedir}'</echo>
>                 <echo>project.build.directory: 
> '${project.build.directory}'</echo>
> </echo>
>               </echos>
>             </configuration>
>           </execution>
>         </executions>
>       </plugin>

> My expectation is that during the build the values should be replaced with 
> the appropriate values which works with Maven 4 (Tested with Maven 
> 4-alpha-13) like this:
> {code}
> [INFO] --- echo:0.5.0:echo (default) @ sub-mod-2 ---
> [INFO] =========================================================
> [INFO] project.rootDirectory: '/projects/props'
> [INFO] session.rootDirectory: '/projects/props'
> [INFO] session.topDirectory: '/projects/props'
> [INFO] project.basedir: '/projects/props/sub-mod-2'
> [INFO] project.build.directory: '/projects/props/sub-mod-2/target'
> [INFO] =========================================================
> {code}
> But the run with Maven 3.9.X it looks like this:
> {code}
> [INFO] --- echo:0.5.0:echo (default) @ sub-mod-2 ---
> [INFO] =========================================================
> [INFO] project.rootDirectory: '${project.rootDirectory}'
> [INFO] session.rootDirectory: '${session.rootDirectory}'
> [INFO] session.topDirectory: '${session.topDirectory}'
> [INFO] project.basedir: '/projects/props/sub-mod-2'
> [INFO] project.build.directory: '/projects/props/sub-mod-2/target'
> [INFO] =========================================================
> {code}
> I have setup a full working example here:
