javafx.controls cannot be resolved to a module in module-info.java


Actual state

I am learning JavaFx and trying to make a reusable component. The project is being developed in VSCode. The project is very simple and deals with a launcher and the reusable component. I was refactoring and when adding the modules everything has stopped working and I can't continue with the refactoring.

Issue

The error displayed inside the module-info is: javafx.controls cannot be resolved to a module. though oddly enough, if I tell Maven to update the project, on some rare occasion the error changes to tell me that the module is empty or doesn't exist.

Source code

The source code ( experimental branch) : https://github.com/Osolemio44/text-area-right This is the structure of the project:

Module-info of the launcher:

module com.adeso.launcher {

    requires transitive javafx.controls;
    requires javafx.fxml;

    opens com.adeso.launcher to javafx.fxml;

    exports com.adeso.launcher;
}

Module-info of the component:

module com.adeso.custom {

    requires transitive javafx.controls;
    requires javafx.fxml;

    opens com.adeso.custom to javafx.fxml;

    // exports com.adeso.custom;
}

Solution

  • After checking all the info of jewelsea, i changed the structure of my project and now it seems to work. I changed to a Maven modules project and created 1 module-info.java inside each maven module.
