[MASSEMBLY-617] add ability to give a fileSuffix to a FileSet

[tcollignon]

Hi

In order to fix https://issues.apache.org/jira/browse/MASSEMBLY-617, I need to add a capability to add file suffix to a FileSet
This PR add this feature, but it need sonatype/plexus-archiver#25 and sonatype/plexus-io#7

Tell me if something goes wrong

The same functionality can be achieved using FileMapper. It would be great if you consider implementing it using file mappers as that would solve other uses cases as well (for example MASSEMBLY-886). For example on how to implement such functionality you can take a look here - https://www.mojohaus.org/xml-maven-plugin/examples/transform-change-extension.html

Hi

Thank for your tips @plamentotev, I will take a look at FileMapper and see if I can update this PR to use directly it.

I don't know a lot of things in this plugin. The InputStreamTransformer is not the same of the FileMapper right ?

[plamentotev]

No. InputStreamTransformer modifies the content of the file (like changing the line ending). FileMapper changes the file name based on some logic (so it is actually a file name mapper). You need to make a similar change to one already did. But instead of String you need to configure an array of org.codehaus.plexus.components.io.filemappers.FileMapper. And after that you need to propagate the array to AbstractPlexusIoResourceCollection. I don't think BaseFileSet accepts FileMapper[] so I think you need to change it as well.

Hope this helps.
