Code review comment for lp:~gesha/linaro-license-protection/remove-artifacts-from-upload

<pfalcon> gesha: I wanted to ask before, what kind of error reporting this gets back to the user? Will jenkins job which does publishing for example will get something into its build log?
<pfalcon> gesha: because otherwise I may suggest for example instead of just removing all files and publishing nothing, publish a text file saying "nothing was published because of lack of BUILDINFO.txt, please add it"
<gesha> pfalcon, right now it shows only "BUILD-INFO.txt is not present in artifacts being published" but add info about nothing published is a good idea
<gesha> will add
