Built the simplest possible scheduling app I could manage. It just does the (prn 'fire) scheduling/cancelling from the public News page that describes how the scheduler works.
It works fine from the repl or using lein run.
When I create an uberjar, I get an IllegalArgumentException from WunderBoss.getComponentProvider (line 134): "Unknown component: org.projectodd.wunderboss.scheduling.Scheduling".
jcrossley on IRC said that it looks like the properties file that does component registration doesn't seem to be getting included in the conversion.
