In code examples, there is code that is not compilable. Here is the code: ```auto import Builtin.Executable; import Builtin.Type; import Navigation.Cd; import java.util.Arrays; import java.util.Scanner; public class Main { public static void main(String[] args) throws Exception { Scanner scanner = new Scanner(System.in); Cd cd = new Cd(); while (true) { System.out.print("$ "); String inputs = scanner.nextLine(); String[] input = inputs.split(" "); String command = input[0]; String argument = String.join(" ", Arrays.copyOfRange(input, 1, input.length)); Cd cd = new Cd(); switch (command) { case "exit" -> System.exit(0); case "echo" -> System.out.println(argument); case "type" -> { Type type = new Type(); type.isBuiltinOrPathOrNon(argument); } case "pwd" -> // Cd has a method to get the current working dir System.out.println(cd.getCwd()); case "cd" -> cd.setCd(argument); default -> { if (!argument.isEmpty()) { Executable executable = new Executable(); executable.execute(command, argument); } else { System.out.println(command + ": command not found"); } } } } } } ``` Here is output: ```auto [compile] [ERROR] COMPILATION ERROR : [compile] [INFO] ------------------------------------------------------------- [compile] [ERROR] /app/src/main/java/Main.java:[5,17] package Navigtion does not exist [compile] [ERROR] /app/src/main/java/Main.java:[14,9] cannot find symbol [compile] symbol: class Cd [compile] location: class Main [compile] [ERROR] /app/src/main/java/Main.java:[14,21] cannot find symbol [compile] symbol: class Cd [compile] location: class Main [compile] [ERROR] /app/src/main/java/Main.java:[42,30] cannot find symbol [compile] symbol: variable argument [compile] location: class Main [compile] [INFO] 4 errors [compile] [INFO] ------------------------------------------------------------- [compile] [INFO] ------------------------------------------------------------------------ [compile] [INFO] BUILD FAILURE [compile] [INFO] ------------------------------------------------------------------------ [compile] [INFO] Total time: 1.809 s [compile] [INFO] Finished at: 2025-05-09T07:53:53Z [compile] [INFO] ------------------------------------------------------------------------ [compile] [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.13.0:compile (default-compile) on project codecrafters-shell: Compilation failure: Compilation failure: [compile] [ERROR] /app/src/main/java/Main.java:[5,17] package Navigtion does not exist [compile] [ERROR] /app/src/main/java/Main.java:[14,9] cannot find symbol [compile] [ERROR] symbol: class Cd [compile] [ERROR] location: class Main [compile] [ERROR] /app/src/main/java/Main.java:[14,21] cannot find symbol [compile] [ERROR] symbol: class Cd [compile] [ERROR] location: class Main [compile] [ERROR] /app/src/main/java/Main.java:[42,30] cannot find symbol [compile] [ERROR] symbol: variable argument [compile] [ERROR] location: class Main [compile] [ERROR] -> [Help 1] [compile] [ERROR] [compile] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

Sorry, I found the problem solution ---

@Didar83 Do you mind sharing what was wrong? Would love to see if we can improve the tester / instructions. ---

I had a different implementation of the CD method, so if in the code examples you will provide the code of another class (Navigation.java), that would be clear ---
