I'm trying to create a JavaFX application using maven but it seems that the JavaFX plugin is creating duplicate dependencies. This is what gets spit out during mvn javafx:run

[WARNING] 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be unique: org.openjfx:javafx-graphics:jar:win -> duplicate declaration of version 17.0.0.1 @ line 129, column 17

I clearly did not list any of these dependencies twice. What am I doing wrong?

Here's the module-info:

module  me.xxx.xxx{
    requires javafx.controls;
    requires javafx.fxml;
    requires javafx.web;

    requires org.controlsfx.controls;
    requires com.dlsc.formsfx;
    requires validatorfx;
    requires org.kordamp.bootstrapfx.core;
    requires eu.hansolo.tilesfx;


    exports me.xxx.xxx;
}

I once had a similar problem. Could you try adding your "openjfx excludes" to controlsfx too? It was necessary in my case.

CodePudding user response：

The problem was that maven was using multiple JDKs to compile the source.

Removing old JDK 8 fixed the issue
