                        </plugin>


                </plugins>

        </build>

</project>

the command I run is 

mvn clean install -Dmaven.test.skip=true

it did not skip  the "tasks" and it always go through the tasks  
I use the "if" attribute and it does not do any check for the property; it 
passes the validation eventhougth the property is not set 

<tasks if="maven.project.alan.mehio.does.not.exit">
                <echo message="Does not skip the tasks "/>
</tasks>
it passes the check (if condition) event the property 
"maven.project.alan.mehio.does.not.exit" does not exist
