I have a issue, not being able to import MediaPlayer in my JavaFX project. I am using IntelliJ with a Maven build, JDK 17 .. I updated the Maven dependencies and I have the JavaFX plugin installed, and it is still not working.. Thanks in advance for any answer/suggestion

            </plugin>
        </plugins>

and the module.info file

module com.example.demo {
    requires javafx.controls;
    requires javafx.fxml;


    opens com.example.demo to javafx.fxml;
    exports com.example.demo;
}

aswell as the VM arguments I added for the build/run

--module-path
"%Path to FX lib%"
--add-modules
javafx.controls,javafx.fxml,javafx.media
Solution

  • If you define a module-info.java file and you want to use the javafx.media module, you need to require that module in your module-info (as suggested by kleopatra in comments).

    module com.example.demo {
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.media;
    
    opens com.example.demo to javafx.fxml;
    exports com.example.demo;
}

    The JavaFX modules are named in the javadoc.

    Oracle provides a brief introduction to the module system, which you should understand when you use it.

    As you are using Maven and JavaFX 17.0.0.1, you also need a dependency in Maven on that version of the javafx-media module.

    <dependency>
    <groupId>org.openjfx</groupId>
    <artifactId>javafx-media</artifactId>
    <version>17.0.0.1</version>
</dependency>

    The java-media dependency version should be the same version as all other JavaFX dependencies. Using either the latest stable version (not an ea version) or the latest long-term service (LTS) release version is recommended.
