JavaFX - unable to compile the MinesweeperGame.java class - Error:(5, 8) java: cannot access javafx.application.Application class file for javafx.application.Application not found

Question about the task

Under discussion

Installed IntelliJ, working fine with all previous tasks, but for this one I can't even succeed in compiling this small amount of code as I get the error: Error:(5, 8) java: cannot access javafx.application.Application class file for javafx.application.Application not found I have followed the instructions to download and install javafx (https://openjfx.io/openjfx-docs/#install-java) and checked that now works fine with a different sample FX application. I've faffed about with checking the path variables etc but no joy. Any ideas - I imagine I'm missing something super obvious..? -- code below --

package com.codegym.games.minesweeper;

import com.codegym.engine.cell.*;

public class MinesweeperGame extends Game{

}

Let's write the entertaining Minesweeper game.

Rules of the game:

The playing field is divided into adjacent cells (squares), some of which contain "mines".
The objective of the game is to clear the field, i.e. reveal all cells that don't contain mines.
If a cell with a mine is revealed, the game is lost. The mines are placed randomly.
If a revealed cell doesn't have a mine, a number appears in it, indicating how many "mined" cells are adjacent to the revealed cell. You can use these numbers to calculate the location of mines.
If the adjacent cells also do not contain mines, an "unmined" region is revealed up to cells that do have numbers.
Cells that you believe to contain mines can be flagged so you don't accidentally reveal them. The number of flags is equal to the number of mines on the game board.
If "unmined" cells are revealed, then the game is won.

Now let's start implementing the game:

To begin, create a MinesweeperGame class, which will implement the logic of the game. This class must inherit the Game class, which is part of CodeGym's cool "game engine".

This and other engine classes are located in the com.codegym.engine.cell package. To use them, the MinesweeperGame class must include the following import statement: import com.codegym.engine.cell.*;

If you did everything right, you will see the playing field when you start the application.

Requirements:

There must be a public MinesweeperGame class.
The MinesweeperGame class must inherit the Game class.
The MinesweeperGame class must have a statement that imports the entire contents of the com.codegym.engine.cell package.

package com.codegym.games.minesweeper; import com.codegym.engine.cell.*; public class MinesweeperGame extends Game{ }

I had similar problems on Linux. Then tried it on Windows instead of Linux and got it working without big problems. Then, I compared the configuration and adjusted it on Linux. This might help a bit: - I've added a module-info.java file in the <xxx>/8.Games/src/ folder that contains the following: module MinesweeperGame { requires javafx.fxml; requires javafx.controls; requires desktop.game.engine; opens com.codegym.games.minesweeper; } - in Project Structure, under Modules > 8.Games there was no 'desktop-game-engine'. I added that by going to Libraries, then added desktop-game-engine.jar (which should be in <xxx>/8.Games/lib/ and applied it to '8.Games'

Oh and in Run > Edit configurations, IntelliJ was complaining there was no main class. I added this: 'com.codegym.games.minesweeper.MinesweeperGame'. This is in the field left of the '--module-path <etc.>'

you need to overrode initialize() method and call the setCellSize with some arguments inside it :)
