What do I need to compile this lanterna maven project from terminal?

Question

I'm following a simple lanterna demo tutorial using maven. The problem is that the program runs perfectly using IDE intellij, but wont compile from terminal. Do I need to include something more in my pom.xml file?

My file Rouge.java opens a simple window with hello world. Error message when trying to compile file from terminal (javac Rouge.java) includes error: package com.googlecode.lanterna.terminal does not exist.

I thought the problem could be that the packages does not compile and tried to add different maven compiler dependencies but the problem remains.

import com.googlecode.lanterna.graphics.TextGraphics;
import com.googlecode.lanterna.screen.Screen;
import com.googlecode.lanterna.screen.TerminalScreen;
import com.googlecode.lanterna.terminal.DefaultTerminalFactory;
import com.googlecode.lanterna.terminal.Terminal;

import java.io.IOException;

public class Rogue {


    public static void main(String[] args) throws IOException {
        Terminal terminal = new DefaultTerminalFactory().createTerminal();
        Screen screen = new TerminalScreen(terminal);

        TextGraphics tg = screen.newTextGraphics();
        screen.startScreen();

        //write a text
        tg.putString(10, 10, "Hello World!");
        screen.refresh();

    }


}

When you run javac/java command on Rogue.java it tries to look for lanterna-3.0.1.jar dependency which is not be available or neither set in the classpath. With the current pom.xml you shared you will still get java.lang.ClassNotFoundException: com.googlecode.lanterna when you execute(mvn install) it on the .jar file. There are couple of options you could look:

• you can define maven-assembly-plugin to your build tag in pom.xml. This will create a fat jar which includes all the dependencies

• if you are in windows you can create .bat script and include your necessary dependency and run the java command. Something like below

  TITLE lanterna demo set classpath=.\lib\* java com.demo.Rogue
