java.lang.AssertionError with latest Leiningen

[terjesb]

Looks like lein-ring 0.7.5 and 0.8.0-SNAPSHOT aren't compatible with the latest master version of Leiningen 2:

$ lein ring server-headless
Exception in thread "main" java.lang.AssertionError: Assert failed: (vector? (:dependencies project []))
at leinjacker.deps$add_if_missing.invoke(deps.clj:43)

at clojure.core$apply.invoke(core.clj:603)
at leiningen.ring.util$update_project.doInvoke(util.clj:46)

Not sure if the problem is with leinjacker or Leiningen?

The updated leinjacker dependency in your commit 22f7387 seems to fix this for 0.8.0-SNAPSHOT with Leiningen 2.0.0-RC1. Thanks!
