What causes this jAnsi NoClassDefFoundError?

Question

In my code i am using the jAnsi Libary. but it spits the following error:

import org.fusesource.jansi.AnsiConsole;
import org.fusesource.jansi.Ansi;



public class SnakeGame {


public static void main(String[] args) {        
    
    AnsiConsole.systemInstall();
    System.out.println( 
    Ansi.ansi().eraseScreen().fg(Ansi.Color.RED).a("Hello").fg(Ansi.Color.GREEN).a(" 
    World").reset() );
    AnsiConsole.systemUninstall();
    }
}

i already tried this PlayFramework 2.3.1 NoClassDefFoundError: org/fusesource/jansi/AnsiOutputStream and it doesnt apply to my problem

Here is the Error it spits:

Exception in thread "main" java.lang.NoClassDefFoundError: org/fusesource/jansi/AnsiConsole at SnakeGame.main(SnakeGame.java:11) Caused by: java.lang.ClassNotFoundException: org.fusesource.jansi.AnsiConsole at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ... 1 more

i tried using Versions 2.10 and 2.01, but the problem stays.

Do you have any Idea how to solve this?

or should i just use another language than java. because i already tried jLine and it doesent work either.switching language would be the last option for me.

gg Guys,

kind regards,

Alwin

The jar is not on the classpath otherwise you wouldn't get that message — g00se, Oct 02 '22 at 14:17

To compile

javac -cp path/to/jansi.jar SnakeGame.java

To run

java -cp path/to/jansi.jar:./ SnakeGame

Alternatively you can export the CLASS_PATH env variable and do them normally
