I finished the whole thing (verification works) but when I try to run the game there's this error: Error: Could not find or load main class com.codegym.games.minesweeper.MinesweeperGame Caused by: java.lang.ClassNotFoundException: com.codegym.games.minesweeper.MinesweeperGame I am wondering if I did something wrong when trying to run it but it seems to look fine before I do it. Any ideas?
