Comment (by NeilMitchell):

 Presumably you {{{need}}} the output of {{{extraObjects}}} at some point?
 When you do that it records their modification times. The {{{--lint}}}
 flag causes it to check the modification time at the end, and it spots it
 is different. Could the insertion into the archive be somehow modifying
 these files? Do you extract them twice?
