How to get PowerShell to play nice with classes in different files?

Question

I am a student trying to complete an assignment in Java. I use VS Code to write, but I use PowerShell to compile and run the code to ensure compatibility outside my IDE. On my laptop I can do this fine running PowerShell from the javafiles location, but as soon as I use my main computer PowerShell complains!

PS C:\FILE LOCATION> javac *.java
Note: Snake.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
PS C:\FILE LOCATION> java Main.java
Main.java:3: error: cannot find symbol
        Controller kontroll = new Controller();
        ^
  symbol:   class Controller
  location: class Main
Main.java:3: error: cannot find symbol
        Controller kontroll = new Controller();
                                  ^
  symbol:   class Controller
  location: class Main
2 errors
error: compilation failed

Here is some of the code:

All of Main.java ->

class Main {
    public static void main (String[] args) {
        Controller kontroll = new Controller();
    }
}

Some of Controller.java ->

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

class Controller {
    private GUI gui;
    private Model modell;

    Controller() {
        gui = new GUI(this);
        modell = new Model(gui);
        }
    //MORE IRRELEVANT CODE
}

I have seen similar issues here, but they have involved a Mains folder that I don't currently have. I only have the files I have made myself, in a flat structure inside the folder I run PowerShell from. I also tried setting classpath directly in PowerShell by using this line:

-classpath .;

Why would PowerShell complain at home, but run fine on my laptop? How can I troubleshoot this further?

Answer 1

The issue resolved itself somehow. I suspect OneDrive, but I have no idea what made it happen.
