    id 'application'  
    id 'org.openjfx.javafxplugin' version '0.0.13'

    // Use Maven Central for resolving dependencies.
    mavenCentral()

    useJUnitPlatform()

javafx {
    version = "19"
    modules = [ 'javafx.controls', 'javafx.fxml' ]
}

But I'm getting

when trying to import javafx.fxml. Any ideas?

Detected code, here are some useful tools:

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If your code is long, or you have multiple files to share, consider posting it on sites like https://pastebin.com/ and share the link instead, that is easier to browse for helpers.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

[gaunt dove]

is the version correct?

surely it's longer than just "19"

[rotund marten]

Well javafx is working

Fxml is not

[gaunt dove]

is it specific to just 19?

or doesnt work on older versions as well

[polar current]

that looks correct to me

JavaFX kind of requires you to set up your module-info.java file correctly. Could you post your current one?

Otherwise you won't be able to access these packages, even though you made them available on your classpath 🙂

Actually you don't need it

what you need are the dependencies and launching the app with javafx:run plugin

[open shale]

You sure? I've always had problems past Java 11 when trying to run JavaFX code that wasn't properly set up within the module system.

[ionic bane]

Yes I am

you probably didn't run with javafx:run, if you run with the default launch config, it won't work

[open shale]

Ah you're right, that should work as long as you don't package it into a runnable. Then it usually breaks 😅

[ionic bane]

you can clone a working sample here https://github.com/openjfx/samples

[ionic bane]

yea

Also think about splitting Main to application, otherwise it may cause weird problems
