compare a currently archived asset to one built in a Jenkins job

[Eric Wood]

I had a situation where a grails build using ivy did not pull in all of the dependencies into a end product .war file.  It took several hours to try and track down what happened.  The .war file is archived with each build.  Is there a way for compare a previously archived asset (size, or contents) with a newly built asset (about to be archived) so I can determine if there are issues with the .war file before it gets deployed and things no longer work?
