Clojure Java Interop - reference to field ... can't be resolved

Question

I am working on a clojure project where I want to create a class in Java and then instantiate that class and call a method from within my clojure code.

My Java code is located in resources/MyClass.java

public class MyClass {

    public static long myMethod() {
        long i = 1; 
        return i;
    }

}

And in my clojure code I have

(import MyClass)
...
(def my-object (MyClass.))
(.myMethod my-object)

I compiled my class and ran lein compile, but when I run my code I get

 Exception in thread "main" java.lang.IllegalArgumentException: No matching field found: myMethod for class MyClass
    at clojure.lang.Reflector.getInstanceField(Reflector.java:271)
    at clojure.lang.Reflector.invokeNoArgInstanceMember(Reflector.java:300)

What am I doing wrong? It looks like the import statement worked, as the the instantiation, but Im not able to call the method. Help is appreciated!

Thanks

for static methods use a / instead of a .

(MyClass/myMethod)
