override Checkstyle resources config

[Javier Gómez]

Hello all,

We are trying to run Checkstyle plugin over a group of resource files, located 
in various directories outside standard directory layout, in project root 
folder,

/module1
  src/main/java
  src/main/resources
  pom.xml
/module2
  ...
/src
/DIR1
/DIR2
pom.xml

To do this, the best way we found, was configure execution of checkstyle plugin 
in parent POM,
and set this directories as resources in checkstyle plugin <configuration>

      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-checkstyle-plugin</artifactId>
        <inherited>false</inherited>
        <configuration>
          <resources>
            <resource>
              <directory>dir1</directory>
            </resource>
            <resource>
              <directory>dir2</directory>
            </resource>
          </resources>
        </configuration>
      </plugin>


I know that the *resources* attribute is defined *readonly*, but this 
configuration works, and the resources in this directories are analyzed.
Is there any possible side effect with this ?
The modules in project inherits a checkstyle configuration from parent 
*pluginManagement* that is not affected by this hack.
