   The generic transformer will actually delegate to other transformers for the actual processing to avoid to reimplement again and again the same logic.
   
   //cc @rfscholte can you review it since you worked on the manifest flavor?

 Review comment:
   Maybe I'm missing an important detail, but in this example is no relocation. So why do it like this?
   And I would have expected that defining both transformers after each other would work, but that requires defining the resource twice. That's probably the thing you're trying to solve.

 Review comment:
   This example is about composing transformers which is not something obvious for most people.
   Defining each one after the other does not work because the relocation transformer is a delagate pattern which only works if there is another transformer saying it what it should handle. Goal is not to not define resource twice but to be able to decorate any transformer with this feature, including the ones with dynamic resource handling (pattern in canTransform for ex).

 Review comment:
   Nested transformers looks more like a XML representation of the Java solution, and it might also expose a design flaw in the plugin.
   It probably makes more sense to start with the resources, and define its transformers:
   
       <resources>
         <resource>
            <includes/>
            <excludes/>
            <transformers/>
         </resource>
       </resources>
   
   I understand that this is quite a different approach, but this looks way more clear to what's happening for the end user. Maybe the code can stay almost the same, but I would map this configuration to the actual transformer calls.

 Review comment:
   Sorry @rfscholte , I don't get this proposal at all. You assume the resource configuration is an input of a transformer but a transformer can actually compute its resources and even create them on the fly without taking any input from the project sources so I don't see how it can work :s.

   Based on your test the input is `foo/bar.txt`, right?

 Review comment:
   Hmm, yes and no. It is foo/bar.txt cause it is an AppendingTransformer but the RelocatingTransformer is not aware of that detail. Think to a GraalVM transformer, it will create resources depending what is in the build so the files will not be configured statically. The RelocatingTransformer still works.
