Replace the 'maven-resources-plugin' (previously declared in the root pom.xml) by Java code in our custom doclet.
The reason is that I didn't found a way to get 'maven-resources-plugin' executed when 'mvn javadoc" is executed,
rather than when "mvn install" is executed. The better alternative would have been to use the <javadocDirectory>
or <javadocResourcesDirectory> maven-javadoc-plugin configuration, but I have been unable to get it to work even
with absolute paths.
