How do I execute maven plugin for parent module only? - maven

Question

So I created this small maven plugin, that would connect to the database server and create all the tables I need for the project. Thing is, that the project consists of multiple modules and I want the plugin to be defined in the parent one. Yet it needs to be executed only once, not separately for each module. I thought that adding "<inherited>false</inherited>" to the plugin configuration would be enough, but apparently it's not.
Here's the pom of my parent project:
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

You should add #aggregator annotation to your plugin's mojo. – Andrew
