Customizing resource mapping to add new binary types about grain HOT 2 CLOSED

Please check Configuration -> Filesystem Layout section of Grain documentation:
http://sysgears.com/grain/docs/latest/#filesystem-layout

You can override binary_files in SiteConfig.groovy, i.e. you can have the line like that in SiteConfig.groovy:

binary_files += [/(?i).*.(pdf)$/]

from grain.

That worked, thanks!

When I applied the change at first, the grain preview server continued to throw exceptions when serving pdfs; it seems that I had to clean first. For my own curiosity, why was a clean necessary?
