mvn plugin not working

Hi guys

I´m trying to do a rollback for the very first time and i´m doing  via maven plugin with this command:
 BUILD FAILURE
[INFO] ------------------------------------------------------------------------

[ERROR] No plugin found for prefix ‘liquibase’ in the current project and in the plugin groupsWhat i´m doing wrong?

Your problem is that you declared a dependency to the liquibase-maven-plugin and not the use of it.

see http://www.liquibase.org/documentation/maven/

You need to include the plugin in the section and a to the jdbc driver of your database.

This is not related to the rollback. Any other goal can not work this way too.
