Is it possible to use the copy goal of this plugin to copy artifactItems conditionally based on age? I am running the build using Jenkins and ideally I would be able to copy files only when they have changed since the last run of my build. The following works to do the copies, but is there a way to restrict the copy in this way?

Java Code:
 <plugin>
        <!--this plugin will copy the artifacts from the artifactory to your local machine (the one running maven)-->
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <version>2.4</version><executions>
          <execution>
            <id>copy-zips</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
            <artifactItems>
                <artifactItem>
                 	<groupId>com.nimsoft.ue</groupId>
      				<artifactId>adminconsole-standalone</artifactId>
      				<version>7.1.0-bnpp-SNAPSHOT</version>
      				<type>zip</type>      				
                  	<overWrite>true</overWrite>
                  	<outputDirectory>${project.build.directory}/resources</outputDirectory>                             	
                </artifactItem>
. . .
I thought I saw a post on this last night, and have been beating my head against google all morning trying to find it again......

Any ideas?
