Newb question - not a good start

I run the follow commands

mvn package # works fine, build successful
java -cp target/cdt-hive-1.0-SNAPSHOT.jar cdt.App  # causes error below

$ java -cp target/cdt-hive-1.0-SNAPSHOT.jar cdt.App
Exception in thread "main" java.lang.BootstrapMethodError: java.lang.NoClassDefFoundError: spark/Request
        at cdt.App.main(App.java:8)

here is the code I used:

package cdt;

import static spark.Spark.*;

public class App {
    public static void main(String[] args) {
        get("/hello", (req, res) -> "Hello World");
    }
}

and my pom.xml file:

You're not packaging dependencies in the JAR.

I suggest using Maven assembly plugin's jar-with-dependencies, see: https://maven.apache.org/plugins/maven-assembly-plugin/usage.html Also, on the same page, see "Creating an Executable JAR". It's handy.
