how to deploy file to repository without filename modified?

[Pak, Young-rok]

I want to deploy some files to repository without modifying filename when deploying 
jar. for example, there is file to deploy in my project like this:

    src/tld/mytag.tld

and, I want to deploy to my repository like this:

    mygroup/tlds/mytag.tld

so, I tried to use maven.xml like this:

  <postGoal name="jar:deploy">
    <artifact:deploy artifact="src/tld/mytag.tld" type="tld" project="${pom}"/>
  </postGoal>

but, failed. mytag.tld copied to:

    mygroup/tlds/myproject-1.0.tld

this is not what I wanted. and found no other way. how can I do that? if there is no 
way to do that, I think artifact plugin must be extended to support that.
