kayak can't recognize kcd in descriptions directory

[plrosat]

Hi all,

I created a file named engine.kcd in ~/kayak/descriptions/...

with the following content: https://github.com/dschanoeh/Kayak/blob/master/Kayak-kcd/src/test/resources/can_definition_sample.kcd

but there is nothing in the descriptions tab when I open kayak.
