How to run maven app with clojure package from jar

Question

I have the following contents in a file src/main/clojure/za/co/pb/maven_test/test.clj:

(ns za.co.pb.maven-test.test
  (:gen-class))

(defn -main []
  (println "Hello world!"))

I also have a POM that has the necessary dependencies on clojure -maven-plugin with compilation execution.

If I execute the command mvn package, I get the file target/maven-test-1.0-SNAPSHOT.jar, and if I look in the classes folder, I have these files in the folder target/classes/za/co/pb/maven_test:

• test.class
• test.clj
• test__init.class
• test$loading__4410__auto__.class
• test$_main.class

This, as far as I know, is suitable.

However, when I run this command:

java -cp target\app-1.0-SNAPSHOT.jar za.co.pb.maven_test.test

I get this:

Exception in thread "main" java.lang.NoClassDefFoundError: clojure/lang/IFn
Caused by: java.lang.ClassNotFoundException: clojure.lang.IFn

Answer 3

If you use leiningen , after creating the flag with lein uberjardo not use java -jar target/your-name.jar, but use java -jar target/your-name-standalone.jar.

The same for boot.

Answer 4

Are all dependencies available? I am not familiar with the clojure.lang.IFn class. Is it from an external library? If you specified a dependency with the provided scope?
