package javafx.fxml does not exist

[Jim Jupiter]

Hi

I have reinstalled IntelliJ IDEA with Java SDK 13

but message appears Error:(3, 19) java: package javafx.fxml does not exist

???

What should I do? Install this? https://gluonhq.com/products/javafx/

[Stephan van Hulst]

You need to install an implementation of Java FX. I don't know about Gluon, I always use OpenJFX, but it probably doesn't matter much.

[Jim Jupiter]

Thank you - it works - I have downloaded Gluon JavaFX  13 SDK from the above mentioned link - then press F4 - open modul settings and then - add lib

[Jim Jupiter]

Hmmm

some error occurred

Caused by: java.lang.IllegalAccessError: class com.sun.javafx.fxml.FXMLLoaderHelper (in unnamed module @0x6a15cd04) cannot access class com.sun.javafx.util.Utils (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.util to unnamed module @0x6a15cd04


Parent root = FXMLLoader.load(getClass().getResource("Main.fxml"));

How are you running your project?  From an IDE?  Which one?  Is the project modular or not?

[Stephan van Hulst]

Looks like you put the fxml dependency on the classpath. You need to put it on the modulepath.

[Jim Jupiter]

as stackoverflow says i have put this to vm options (last two)

Edit: if I delete two lines - same error

IDE  IntelliJ IDEA

modular??? don't know

[Knute Snortum]

I bet you haven't added the JavaFX library to the project.  Here are instructions on how to do that.

[Stephan van Hulst]

Do you have a module-info.java file in your project? If so, please show it to us.

[Jim Jupiter]

same error again

modul-info.java don't see it

I reinstalled IDEA and then Import the project - maybe there some fault?

[Stephan van Hulst]

Please show us your complete project directory structure, and copy and paste the output from your Run Tool Window when you run the application.

Can you show the output after having added the --module-path and --add-modules switches to your VM options?

Now IntelliJ did not start

If you already have a 64-bit JDK installed - define a java home variable

Failed to create JVM path. Path C: program files\java\jdk 13.0.1

appears



Edit:

JAVA_HOME C:\Program Files\Java\jdk-13.0.1
IDEA_JDK_64 C:\Program Files\Java\jdk-13.0.1

I:\javafx-sdk-13.0.1

[Knute Snortum]

I don't see anywhere on the command line where you set your module path, e.g.

"C:\Program Files\Java\jdk-13.0.1\bin\java.exe" --module-path /path/to/java/javafx-sdk-11.0.2/lib --add-modules javafx.base,javafx.graphics...

[Stephan van Hulst]

Knute, -p is a shorthand for the module path.

It seems that IntelliJ just doesn't deal well with mixed classpath/module projects.

You might want to make your project into a full blown module by adding a module-info.java to the root package and declare that your project requires javafx.controls, javafx.fxml and javafx.graphics.

You might also have to open your module to some JavaFX modules, but your compiler will tell you which ones.

Thanks for clearing that up.

I still don't think the vm args are set correctly.  I tried (in Eclipse) to only use the base and graphics modules and I got a runtime error executing the code.  I think you need the controls module, like this:
--add-modules=javafx.controls -p "C:\Program Files\Java\javafx-sdk-13.0.1\lib\javafx.base.jar;C:\Program Files\Java\javafx-sdk-13.0.1\lib\javafx.graphics.jar;C:\Program Files\Java\javafx-sdk-13.0.1\lib\javafx.controls" Or even more simply:
--add-modules=javafx.controls -p "C:\Program Files\Java\javafx-sdk-13.0.1\lib"

[Stephan van Hulst]

For an FXML application you also need to add the javafx.fxml module to the root nodes of the module graph. It just appears that IntelliJ either doesn't understand what modules to add to the graph, or the OP didn't add the module like they said they did.

[Jim Jupiter]

Does it work with Eclipse or Netbeans? Any know-how?

Try it now this way - didn't understand it - but maybe it works

[Jim Jupiter]

Nope        

I have installed Eclipse 2019-09

installed e(fx)clipse 3.6.0

Now I'm here

Error: Unable to initialize main class DBFX.Main
Caused by: java.lang.NoClassDefFoundError: Stage

all fx commands are red x

and enough trouble for today ... just relaxing  

Edit: Now it looks like this



Exception in thread "main" java.lang.Error: Unresolved compilation problem:
The method launch(String[]) is undefined for the type Main

at DBFX2020.Main.main(Main.java:25)

[Stephan van Hulst]

You're missing a dependency on javafx.graphics.

Honestly, you can save yourself a lot of pain if you just use Maven. All you need to do is declare a dependency on javafx.controls and javafx.fxml and you're good to go. To run the application, use the javafx:run Maven goal.

[Knute Snortum]

You don't have an import for Application.

[Jim Jupiter]

After a couple of retries - now it works ... didn't know exactly ... but this works for me now in IntelliJ IDEA 2019-3

- Creating a JavaFX Project in IDEA

- File / Project Structure - setting Libraries to javaFX-SDK path (choose + and Java)

- In Run / Edit Configurations following line works for me --->  

--module-path "c:\Program Files\java\javafx-sdk-13.0.1\lib” --add-modules=javafx.controls,javafx.fxml

[Knute Snortum]

Thanks for posting your solution!

[Stephan van Hulst]

Indeed! Have a cow
