How do i correctly compile jnativehook on intellj?

Question

i'm quite sure i have everything right but it just won't compile the example posted on the website

Here's my POM.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>

<groupId>com.1stleg</groupId>
<artifactId>jnativehook</artifactId>
<version>2.1.0</version>
<name>JNativeHook</name>

and here's the error output from cmd:

PS C:\Users\XXX\IdeaProjects\Defa_Kalenteri\src\main\java> javac -classpath ./JNativeHook.jar 
GlobalKeyListenerExample.java
GlobalKeyListenerExample.java:2: error: package org.jnativehook does not exist
import org.jnativehook.GlobalScreen;
                  ^

import org.jnativehook.NativeHookException;
                  ^

                           ^
GlobalKeyListenerExample.java:5: error: package org.jnativehook.keyboard does not exist
import org.jnativehook.keyboard.NativeKeyListener

Here's my github if you want to have a go at it. Find the file GlobalKeyListenerExample.java and try to compile it.

You don't have jnativehook listed as a dependency. The pom you listed is not the pom you should be using for your project, that's the pom that defines the artifact you're trying to use. Your pom should look more like this:

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
