Something is still off here. Leiningen compiles the IFoo interface first but
compilation of Foo still cannot find IFoo. I've included the (:requires)
statement as described. (:gen-class) is part of the ns declaration. Any
other ideas?
--- src/proj/IFoo.clj ---
(ns proj.IFoo
(:import ...)
(:gen-interface
:methods ...))
--- src/proj/Foo.clj ---
(ns proj.Foo
(:require proj.IFoo)
(:import ...)
(:gen-class
:implements [proj.IFoo]
...))
Thanks,
-Nick
