Maven - delegate plugin execution to submodule

Question

I've got a super POM gathering versions, plugin & dependency definitions for its 2 child submodules: one for a webapp (running with jetty:run), the other one for DB migrations ("running" with liquibase:update).

This works fine so long as I changed the directory to one of the submodules'. However, when I run jetty:run or liquibase:update on the parent POM, I'd like to see the plugin execution "forwarded" to the corresponding submodule.

Do you have any idea if such a thing can be achieved?

Thanks in advance,

Rolf

P.S.: sorry for the late update

If you have made an mvn install before other steps you can use

mvn -pl ChildModule lifecycle

from the root level of your project.
