Plamen Totev updated MASSEMBLY-803:
-----------------------------------
    Description: 
Hi,

Currently when using {{dependencySets}} with {{unpack}} set to {{true}}, there is no way to set the output file names mapping. As plexus-io supports file names mapping, I think it will be relatively easy to add such option.

Consider the following scenario. You want to distribute tomcat as part of your product. You could add something like that;
{code:xml}
  <dependencySets>
    <dependencySet>
      <includes>
        <include>org.apache.tomcat:tomcat:8.0.33:zip</include>
      </includes>
      <unpack>true</unpack>
    </dependencySet>
  </dependencySets>
{code}

So far so good. But the zip archive contains {{apache-tomcat-8.0.33}} as root folder.What if I want to distribute it under {{tomcat}}? There is no way(AFAIK) to just extract sub folder of the archive. Of course there is {{<excludes>}} tag but the matched files will be still under {{apache-tomcat-8.0.33/...}}

The use of {{FileMapper}} for example may strip the root folder (the {{RegExpFileMapper}} seems like a perfect candidate). 

What do you think about such feature?

p.s. Not quite sure where is the proper place to discuss such improvements requests - here or in the mailing list. So excuse me if this is not the proper place.
