overriding goal's configuration from command line?

[amaresh mourya]

Hi All,

I have a POM which has a plugin. I have configured it to use some specific
settings at the time of command line invocation of the goal. I set these
configurations in execution ID as "default-cli".

This MyPlugins:hiPlugin:1.0:hi goals just prints the output in format of :
${person} says ${greetings}
When I ran goal (MyPlugins:hiPlugin:1.0:hi) on command line I got the
expected output that was : "Chandan says Welcome"
But My question is why am I not able to override these configurations from
command line, I wanted to run goal with parameter (MyPlugins:hiPlugin:1.0:hi
-Dperson=Vishal) to get the output as "Vishal says Welcome". But I am still
getting output "Chandan says Welcome".

Here is my POM.

                       <id>default-cli</id>
                        <goals>
                            <goal>hi</goal>
                        </goals>
                         <configuration>
                             <greetings>welcome</greetings>
                             <person>chandan</person>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
