gen-class exposes

Clojure:

(ns test.example
 (:import (com.example Example)))

(gen-class
  :name test.Example
  :extends com.example.Example
  :main false
  :exposes {PROTECTED_FIELD {:get PROTECTED_FIELD :set PROTECTED_FIELD}}
  :methods [[fieldInfo [] void]])

(defn -init [this]
  [[] (atom {:PROTECTED_FIELD (.PROTECTED_FIELD this)})])

(defn -fieldInfo [this]
  (println (.PROTECTED_FIELD this)))

Java:

package com.example;

public class Example {

    protected static final String PROTECTED_FIELD = "this is a field";

    public void asdf() { }
}

More java:

package tests;

import java.lang.reflect.Constructor;
import java.lang.reflect.Method;

import test.Example;

public class Tests {

  public static void main(String[] args) throws Exception {
      Example e = new Example();
      e.fieldInfo();
/*
      Class c = Class.forName("test.Example");
      for (Constructor ctor : c.getConstructors()) {
          System.out.println("Constructor:");
          for (Class p : ctor.getParameterTypes()) {
              System.out.println("  " + p);
          }
      }
      for (Method m : c.getMethods()) {
          System.out.println(m.getName());
          for (Class p : m.getParameterTypes()) {
              System.out.println("  " + p);
