I'm trying to add javafx.media module. I'm using IDEA with Maven build tool. I did some online searches and added required module to modules-info.java and javafx-media dependency to pom.xml. The prebuild found no error but when I tried to build the project it said: "java: package javafx.scene.media does not exist". I tried to Google it again but found nothing except what I've done. So please help me. I'm new to Maven and Java 9 Modules.

Here is my module-info.java file content

module com.example.minesweeper {
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.media;

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

Here is my pom.xml file content

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Sometimes there are other packages not found too but I don't know how do they not exist and I just revert the project to fix them. I hope I can find a general solution to these missing packages.

    Is there a good reason why you are using a `20-ea+4` version instead of `20.0.1`? https://central.sonatype.com/artifact/org.openjfx/javafx-controls/21-ea%2B23/versions and why is `javafx-media` using version 17 instead of `20.0.1`? – khmarbaise Jun 26 '23 at 10:42

    Thank you so much for your comment. I tried javafx-media 20.0.1 and it worked. I don't know why the 17 version contains the package javafx.scene.media but it missing some classes and it couldn't be found. So it's all about my ignorance of Maven. – Giao Le Xuan Jun 26 '23 at 11:09
  • No problem glad to help. Post your knowledge as answer that might help others in the future... – khmarbaise Jun 26 '23 at 14:42
  • I'm not really understand what happened so I don't want to post an answer. The versions I used was defaulted by IDEA and I didn't understand much about how Maven works. So the temporary solution is just switch to a newer versions which can be found on https://mvnrepository.com/ and modifying pom.xml. For general problem of missing some random packages, I haven't known the solution yet. – Giao Le Xuan Jun 26 '23 at 15:29
  • IDEA and I didn't understand much about how Maven works ? Really.. it does understand a lot... The versions should be looked up in central repository https://central.sonatype.com/ – khmarbaise Jun 26 '23 at 15:33
  • Note that there haven't been any packages added to or removed from the `javafx.media` module between versions 17 and 20. So, while the mismatched versions seemed to be the problem, I don't know why that lead to a "package does not exist" error. – Slaw Jun 27 '23 at 02:30
