My JavaFx
application is running perfectly well from source but When I'm compiling to a single jar file I get error :
Error: JavaFX runtime components are missing, and are required to run this application.
I'm using Maven
as my repository manager and My install with Maven is sucessfull.
Note: In my Intellij
build artifact I can see that Intellij
include JavaFx
and all its libraries
a) For my maven project the trick was to use an extra starter class that does not inherit from javafx.application.Application:
public class GUIStarter {
public static void main(final String[] args) {
GUI.main(args);
}
}
The JavaFx dependencies are included in my pom.xml as follows:
<!-- JavaFx -->
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-base</artifactId>
<version>12</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-controls</artifactId>
<version>12</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-graphics </artifactId>
<version>12</version>
<classifier>win</classifier>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-fxml</artifactId>
<version>12</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-web</artifactId>
<version>12</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-media</artifactId>
<version>12</version>
</dependency>
<dependency>
<groupId>org.openjfx</groupId>
<artifactId>javafx-swing</artifactId>
<version>12</version>
</dependency>
In order to include fxml files in your build, you might need to define them as resource:
!-- define JavaFx files as resources to include them in the jar -->
<resource>
<directory>${basedir}/src/main/java/foo/baa/view</directory>
<filtering>false</filtering>
<targetPath>foo/baa/view</targetPath>
</resource>
b) As an alternative, an extra maven plugin "javafx-maven-plugin" could be used to build the javafx appication, see example project at https://openjfx.io/openjfx-docs/#maven (This did not work for me. I have several pom files and want to reference the javafx dependencies in a sub project. My main class could not be found by the javafx-maven-plugin.)
