Java FX Modular Application, Module not found (Java 11, Intellij)

Question

Hello I have a problem with my modular Java FX Application.

First of all I created a JavaFX Project with the Intellij Wizard.
I added the Java FX lib:

And the JavaFX modules get recognized. My module-info.java:

I also added the VM options:

But I always get this errormessage:

"Error occured during initialization of boot layer
java.lang.module.FindException: Module HelloFX not found"

Thank you.

Answer 1

When you get the error:

Error occurred during initialization of boot layer

java.lang.module.FindException: Module HelloFX not found

it means that the path to the module in question in --module-path is wrong and the module can't be found.

Check the output folder. Based on your first picture, the output of the HelloFX project goes to out , but your VM options you are setting the relative path to mods .

You can configure the compiler output from IntelliJ -> File -> Project Structure -> Project -> Project Compile Output .

On Windows by default, when you create a JavaFX project, IntelliJ points to \\path-to\\HelloFX\\out .

Then you either modify that compile output path to \\path-to\\HelloFX\\mods , or your VM arguments:

--module-path "\path-to\javafx-sdk-11.0.1\lib;out\production"
