Creating executable JAR in IntelliJ (Java 18, JavaFX 18 Maven project), "WARNING: Unsupported JavaFX configuration..."

Question

I have a Java 18, JavaFX 18 Maven project which has a lot of libraries, beside the javaFX libraries, that needs to be included in the artifact. I want to create an artifact, a jar, which contains all dependencies. I started following this video to create the jar: https://www.youtube.com/watch?v=UKd6zpUnAE4

Summarizing my steps, and referring to the steps in the video:

1. In IntelliJ in Project Structure/Project Settings/Libraries I removed all Maven added libraries, and added C:\Program Files\Java\javafx-sdk-18.0.2\lib

2. After, in Run/Edit Configurations... I added a VM options, and in that window I added

   --module-path "C:\Program Files\Java\javafx-sdk-18.0.2\lib"

   --add-modules javafx.controls,javafx.fxml

3. After, in the video, "Ken" the host of the video creates a class, with a main() method, that runs the application original main() class. I did not need this step, because I already has a class that does the same.

4. After, File/Project Structure/Project Settings/Artifact/ I added a JAR/From modules with dependencies/ and I choose the class I recently created, and shortened the path until the source folder (src)

5. Following this step, after I clicked add (+), and added the content of "...javafx-sdk-18.0.2/bin" all dll's and everything (all files).

Here, at this point, separate from the video, I also created a folder named "jars" and put all Maven dependencies jars in that folder.

According to the video, after these steps, with a double click on the artifact the jar runs without a problem.

However, I needed I more step. My dependency jars are signed jars, so I needed to open the artifact with WinRAR and remove the *.SF, *.DSA and *.RSA files. Earlier this caused me problems so I followed the idea here: Invalid signature file digest for Manifest main attributes exception while trying to run jar file, and here: "Invalid signature file" when attempting to run a .jar

After this, everything should be fine, however not :( The jar doesn't run on double click. When I run it from command line, I receive the following error:

$ java -jar jHasher.jar

I have searched the following error message. I also found some posts on StackOverflow, however they are not clear to me, and I was not able to fix this issue. Please, guide me how to proceed. All suggestions are highly appreciated.

Answer 1

After several hard day, I was able to create the executable jar. I'd like to share the know-how with you.

After 5th step, skipping the WinRAR for removing the *.SF, *.DSA and *.RSA files. I added maven-shade-plugin to my pom.xml. The shade plugin can automatically remove these unwanted files, but unfortunately by itself cannot create a runnable JAR, because throws again exceptions and doesn't run on double click (JavaFX 18 Maven IntelliJ: Graphics Device initialization failed for: d3d, sw Error initializing QuantumRenderer: no suitable pipeline found).

To avoid this exception and include the unlocated/missing JavaFX files we have to repack the already packed JAR. To do that, I used the spring-boot-maven-plugin. After setting up the plugins (code below), you have to run the plugins with maven in a correct order! My maven command was the following: mvn clean package spring-boot:repackage

That it, finally the created JAR (JAR of the JAR) can run on double click.

My pom.xml's corresponding parts:

1. Shade plugin setting:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>3.4.1</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
   
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
   
                        <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>controller.Start</mainClass>
                        </transformer>
   
                    </transformers>
                    <minimizeJar>true</minimizeJar>
                    <filters>
                        <filter>
                            <artifact>*:*</artifact>
                            <excludes>
                                <exclude>META-INF/*.SF</exclude>
                                <exclude>META-INF/*.DSA</exclude>
                                <exclude>META-INF/*.RSA</exclude>
                            </excludes>
                        </filter>
                    </filters>
                </configuration>
            </execution>
        </executions>
    </plugin>
   

2. The Spring-boot-maven-plugin setting (this should be placed outside the plugins section, at the very end of the pom.xml):

    <pluginManagement>
        <plugins>
            <plugin>
                <!-- mvn clean package spring-boot:repackage -->
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                        <configuration>
                            <classifier>spring-boot</classifier>
                            <mainClass>
                                controller.Start
                            </mainClass>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </pluginManagement>
   

Make sure to run the plugins in the correct order, as mentioned above! I found this resource very useful: https://www.baeldung.com/spring-boot-repackage-vs-mvn-package
