ArchiveTask#needed? does not detect sources properly
----------------------------------------------------

                 Key: BUILDR-231
                 URL: https://issues.apache.org/jira/browse/BUILDR-231
             Project: Buildr
          Issue Type: Bug
    Affects Versions: 1.3.2
            Reporter: Ittay Dror
             Fix For: 1.3.4


#needed? iterates over @paths, getting 'sources' from each and then checking each source directly for existence and timestamp.

however, the packaging itself is done by iterating the actions of each path. some actions descend into the source if it is a directory and package individual files (see include_as)

scenario:
directory 'foo' contains file 'baz'. 
in the project definition i  use 'package(:jar).include('foo', :as => 'bar')'
call 'package' task on the project => package is created with 'bar/baz'
modify 'baz'
call 'package' task on the project => nothing is done. (the reason is that needed? will check the timestamp of 'foo' not 'baz')

note that this also means that excluded sources may trigger tasks unnecessarily (since exclusion is only checked in the action).

suggestion: the action associated with each source should use the paths returned by the source block as is, without descending. the source block should do this.
