Maven multi-project dependency management for checkstyle plugin - maven

Question

I'm trying to use the maven-checkstyle plugin for a multi-module project here is my projec structure
|pom-root
| -- my-checkstyles
| |-- pom.xml
| |-- checkstyles
| |-- checkstyles.xml
| -- my-war
| |-- pom.xml
| -- my-ejb
| |-- pom.xml
| -- my-ear
| |-- pom.xml
| -- pom.xml
and here is the pom.xml for my pom-root project :
<project
xsi:schemaLocation=
"http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns=

When I execute mvn site it fails unless I have the checkstyle project installed in the repository, which is pretty annoying because if a make a slight change in the file I need to install it again in the repo.
I know Maven is supposed to work this way, but is there a way to configure the root pom to resolve the dependency to the checkstyle project at compile time and not get it from the repo?
I tried using maven options "--also-make" and "-pl" but I couldn't get it working.
Also I know I can tell checkfile to look for the checkstyle file using the file:/// protocol (thats how I'm doing it now) but I would rather find an alternative way.
Thanks in advance
