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:
        <!--this plugin will copy the artifacts from the artifactory to your local machine (the one running maven)-->
. . .
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?
