I paid attention to the line:
Caused by: java.lang.IllegalArgumentException: Invalid URL: Invalid URL or resource not found
at javafx.scene.image.Image.validateUrl(Image.java:1125)
at javafx.scene.image.Image.<init>(Image.java:618)
at main.HomePageController.<init>(HomePageController.java:56)
but I didn't understand what the "Invalid URL" has to do with it, if everything works fine in the IDE. I am using Intellij IDEA 2021.2 (Community Edition). SDK is "16 version 16.0.2"
I built the JAR file as follows:
File -> Project Structure -> Artifacts -> + -> JAR -> From module with dependences
indicated the Main Class: main.Launcher
and a directory for META-INF / MANIFEST.MF: C:\Users\user\IdeaProjects\MP3Player\src
then in the jar I added all the .dll files from the directory C:\Program Files\Java\javafx-sdk-16\bin
MANIFEST.MF file:
Manifest-Version: 1.0
Main-Class: main.Launcher
Project structure:
MP3Player

In "Edit configurations" I added the parameter "VM parameters":
--module-path
"C:\Program Files\Java\javafx-sdk-16\lib"
--add-modules=javafx.controls,javafx.fxml
--add-modules=javafx.controls,javafx.media
The main class is written in pom.xml:
<mainClass>main.Launcher</mainClass>
I hope I have indicated everything that can help to understand the essence of the problem. I tried to recreate the project, did the build on Gradle, but jar-file does not work. PLEASE tell me what I'm doing wrong)
