How do I set local-paths for ritz.nrepl.middleware/wrap-javadoc?

In api docs for nrepl-middleware wrap-javadoc it says that it 'accepts local-paths a space separate list of paths'

How do I set this?

I've tried the following in my profiles.clj

{:user {:plugins []
    :jvm-opts ["-Xmx4G"]
    :injections [(require 'clojure.repl)]
    :warn-on-reflection true
    :dependencies [[ritz/ritz-nrepl-middleware "0.7.0"]]
    :repl-options {:nrepl-middleware 
                   [ritz.nrepl.middleware.javadoc/wrap-javadoc :local-paths "/usr/local/share/javadocs/7/docs/api"]
                   }}}

But that causes the following exception when I execute nrepl-jack-in

Starting nREPL server...
Mark set
error in process sentinel: nrepl-server-sentinel: Could not start nREPL server: Reflection warning, NO_SOURCE_PATH:1:483 - reference to field getLocalPort can't be resolved.

If I wrap :local-paths "..." in a map I don't get any javadoc middleware

If you look at the example of the nrepl-middleware on its github page, you will find that the vector to :nrepl-middleware sbould be a vector of middleware functions where as you are passing it a string path and that's why the exception "String cannot be cast to IFn".

As far as the local-paths is concerned that's something which is send by the nrepl client in the java-doc request itself. You can set local-paths in Emacs by calling:

(setq nrepl-ritz-javadoc-local-paths (list "/usr/local/share/javadocs/7/docs/api"))
