--------------------------------------

             Summary: Add file name mapping option when extracting dependencies
                 Key: MASSEMBLY-803
                 URL: https://issues.apache.org/jira/browse/MASSEMBLY-803
             Project: Maven Assembly Plugin
          Issue Type: Improvement
          Components: dependencySet, moduleSet
            Reporter: Plamen Totev
            Priority: Minor


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. But
what if I want to distribute it under tomcat? there is no way 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.
