native2ascii copies the resources in all parent directories

I'm building a maven project with some localization files.
I've placed them in src/main/resources/native2ascii/configuration/countries/
I have configured native2ascii to use that source, and use src/main/resources/configuration/countries/ as dest

So this is the portion of my pom.xml

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>native2ascii-maven-plugin</artifactId>
<version>1.0-alpha-1</version>
<executions>
<execution>
<id>1</id>
<goals>
<goal>native2ascii</goal>
</goals>
<configuration>
<encoding>ISO-8859-1</encoding>
<src>$

/src/main/resources/configuration/countries/</dest>
</configuration>
</execution>
</executions>
</plugin>

In my result .war package, the .properties files that native2ascii handles, are correctly placed in: /WEB-INF/classes/configuration/countries/
But, they are copied also in other directories: /WEB-INF/classes/countries/ and /WEB-INF/classes/

This actually should'n happen
