I updated my Maven-based JavaFX project from Java 8 to Java 11. Because Java 11 does not include JavaFX anymore, I included the JavaFX Maven plugin in my pom.xml as explained in https://openjfx.io/openjfx-docs/#IDE-Eclipse:
<properties>
...
<javafx.version>11.0.2</javafx.version>
...
</properties>
<dependencies>
...
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>${javafx.version}</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-fxml</artifactId>
<version>${javafx.version}</version>
</dependency>
</dependencies>
...
<plugin>
<groupId>org.openjfx</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>0.0.3</version>
<configuration>
<mainClass>my.javafx.main.class</mainClass>
</configuration>
</plugin>
However, when I run it with mvn clean javafx:run as instructed, I get the error below. What can be wrong?
EDIT: please note that the initial messages about module names are warnings. I am not sure they are related to the error.
It seems the crucial error is the exception java.lang.ClassNotFoundException: com.sun.javafx.css.parser.CSSParser.
