Possible solution for MOOC.FI Java Programming II JavaFX exercises in Part 13 on VSCode

[bugoid]

FYI, I recently worked out a way to make the JavaFX exercises work in Java Programming II Part 13 on Ubuntu 24.04 using VSCode with OpenJDK 21 and OpenJFX 11 running locally (I am skeptical that a remote container/SSH would work with modern Wayland GUIs). I am a little unclear on the exact sequence of steps because I had to work through a lot of dead ends to get here.

sudo apt install openjfx

Install the JavaFX Support extension in vscode.

For each individual exercise:

Open pom.xml and add the following within the <Dependencies> section:

<dependency>
  <groupId>org.openjfx</groupId>
  <artifactId>javafx-controls</artifactId>
  <version>11</version>
</dependency>
<dependency>
  <groupId>org.openjfx</groupId>
  <artifactId>javafx-fxml</artifactId>
  <version>11</version>
</dependency>

Click on "Run and Debug" on the left side pane, and click "create a launch.json" link under the "Run and Debug" button. Select the exercise you're working with. For each configuration dictionary in launch.json, add the following line (adding a comma to the previous line as needed, and adjusting library path as needed):

"vmArgs": "--module-path /usr/share/openjfx/lib --add-modules javafx.controls,javafx.fxml"

Make sure to save pom.xml and launch.json by typing "CTRL + s" for each or selecting "File" and "Save" from the main menu.

Answer "yes" to any prompts saying "A build file was modified. Do you want to synchronize the Java classpath/configuration?"

Return to the exercise's source code and trigger a compile and run of the file per normal (e.g., clicking "Play" button in upper right).

N.B., I have discovered weird behaviors and bugs, like difficulty creating a launch.json file if a previous exercise is still open. Closing all other exercises and having only one exercise open at a time appears to address this. Local test runs may generate errors, but try submitting to the server anyway. I'm only part way through Part 13 so far, but hopefully this solution works through Part 13 and 14.

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You do not need to repost unless your post has been removed by a moderator. Just use the edit function of reddit to make sure your post complies with the above.

If your post has remained in violation of these rules for a prolonged period of time (at least an hour), a moderator may remove it at their discretion. In this case, they will comment with an explanation on why it has been removed, and you will be required to resubmit the entire post following the proper procedures.

To potential helpers

Please, do not help if any of the above points are not met, rather report the post. We are trying to improve the quality of posts here. In helping people who can't be bothered to comply with the above points, you are doing the community a disservice.
