In project I used library org.json. Everything works fine in the editor. When I build the project, move the "out" folder to another machine (Debian), and run Main.class via console, I get this error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONObject
        at gro.nn.lead_updater.Config.<init>(Config.java:30)
        at gro.nn.lead_updater.Config.getInstance(Config.java:23)
        at gro.nn.lead_updater.Main.main(Main.java:23)

I don't see any changes before and after adding the library in the out folder. Project structure below

Here project dependencies

    You also need to have the library on the classpath when running your application. – Mark Rotteveel Apr 13 '22 at 15:15

    See https://www.jetbrains.com/help/idea/debugging-your-first-java-application.html. You need to create the artifact jar with all the dependencies included in it (with the class files from the jars as well). See also https://www.jetbrains.com/help/idea/artifacts.html. – CrazyCoder Apr 13 '22 at 15:48

    You need to use `java -cp ; com.company.Main`, or if it is an executable jar, `java -jar ` and make sure that the other libraries are listed in the the `Class-Path` manifest entry, and that those libraries are in the right relative location. – Mark Rotteveel Apr 14 '22 at 07:18
