How to get path relatively to the parent project pom

[Anatol Pomozov]

Hi.

I am trying to configure jalopy plugin for maven2. I have single jalopy
configuration file that will be used in my project for all submodules.
I would like to store jalopy in VCS (it means on filesystem not on HTTP
server)

Jalopy configuration stored in root project
${root}/src/main/resources/jalopy.xml

Now I need to tell jalopy plugin where this configuration file located. I am
trying to configure plugin in following way

   <build>
       <plugins>
           <plugin>
               <groupId>org.codehaus.mojo</groupId>
               <artifactId>jalopy-maven-plugin</artifactId>
               <version>1.0-SNAPSHOT</version>
               <configuration>

<convention>${basedir}/src/main/resources/jalopy.xml</convention>
               </configuration>
           </plugin>
       </plugins>
   </build>

But it does not work when I try to run jalopy plugin from submodule, because
${basedir} calculated relatively to submodule directory.

So there is a question. Is any way to get path relatively root project?? (I
have 3 layer in POM hierarchy rootPom->applicationPom->submodulePom)


Thanks for your help.
