add possibility to have consistent output results in "properties" and "copy-dependencies" goals when using snapshot dependencies

after build project described in attached pom.xml I have following result:

[INFO] --- maven-dependency-plugin:2.4:copy-dependencies (copy-plugin-dependencies) @ org.test ---
[INFO] Copying wss4j-1.6.6-SNAPSHOT.jar to E:\tmp\maven\target\classes\lib\wss4j-1.6.6-20120316.095133-6.jar
[INFO] Copying cxf-bundle-2.6.0-SNAPSHOT.jar to E:\tmp\maven\target\classes\lib\cxf-bundle-2.6.0-20120323.063849-49.jar

[echoproperties] #Ant properties
[echoproperties] org.apache.cxf\:cxf-bundle\:jar=E\:\\apache-maven-3.0.2\\repo\\org\\apache\\cxf\\cxf-bundle\\2.6.0-SNAPSHOT\\cxf-bundle-2.6.0-SNAPSHOT.jar
[echoproperties] org.apache.ws.security\:wss4j\:jar=E\:\\apache-maven-3.0.2\\repo\\org\\apache\\ws\\security\\wss4j\\1.6.6-SNAPSHOT\\wss4j-1.6.6-SNAPSHOT.jar

in my project I need to create a special xml configuration file which will describe copied dependencies libraries.

for this I use maven resource filtering mechanism and describe in configuration template file placeholders like ${org.apache.ws.security:wss4j:jar} which will be replaced by maven from its properties (populated in my case by "properties" goal). I also use "propertymapper-maven-plugin" plugin for retrieve only jar file name from path in the property value.

but in case dependencies artifacts are snapshots versions as you can see from above example in configuration file library name will be "wss4j-1.6.6-SNAPSHOT.jar" and name of real copied library will be "wss4j-1.6.6-20120316.095133-6.jar".

It would be good to have a property in "copy-dependencies" goal configuration which will force to copy dependencies using version with "-SNAPSHOT" qualifier (as it was resolved) instead of using timestamped version.
