Description

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:

        <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:

[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] =========================================================

But the run with Maven 3.9.X it looks like this:

[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] =========================================================
