How to call super class when extending a Java class using genclass in Clojure?

I want to call a method in the super class from Clojure. I am extending a Java class using :gen-class.

(ns subclass.core (:gen-class :extends Baseclass)) (defn greet [] "Hello from core") ; how to call super.greet()? (defn -main [& args] (greet))

Java Baseclass

public class Baseclass { public String greet() { return "Hello from Baseclass"; } }

Edit: as the linked example I tried

 (ns subclass.core (:gen-class :extends Baseclass :exposes-methods {greet pgreet}) (:import Baseclass)) (defn greet [] (.pgreet (Baseclass.))) (defn -main [& args])

But when I call (greet) I am getting the error

IllegalArgumentException No matching field found: pgreet for class Baseclass clojure.lang.Reflector.getInstanceField (Reflector.java:271)

Is this the right way to call the super class method?
