[FIXED] Eclipse external libraries

Issue

I am currently experiencing issues whilst using external libraries in Eclipse. Whenever I am trying to launch my program it throws a NoClassDefFound exception. I am obviously doing something wrong. Could someone re-explain for me how to properly include them into your project? (Yes I have already done a lot of research on this and got recommended to use Maven dependencies which I don‘t want. Also I have found some threads that were more relevant to my issue but nothing helped. So yeah, I would really appreciate it if someone could explain what exactly to do.)

I am using the newest ver of eclipse together with java 8 (usually 13 but that did not fix my error). It only throws the exception on runtime so, it compiles without any errors.

Project setup: http://prntscr.com/udsxts

Manifest file:

Manifest-Version: 1.0
Main-Class: me.sxlver.consoleclient.Main
Class-Path: lib/java-json.jar lib/snakeyaml-1.26.jar

Exception:

Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONObject
        at me.sxlver.consoleclient.Main.main(Main.java:20)
Caused by: java.lang.ClassNotFoundException: org.json.JSONObject
        at java.net.URLClassLoader.findClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)
        at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
        at java.lang.ClassLoader.loadClass(Unknown Source)

(I am just creating an instance of JSONObject)

Solution

From the Run menu, select Run Configurations...

Select Dependencies tab, then click on button Add External JARs

A file chooser window will appear. Navigate to the location of the relevant JAR and select it.
