Configuring JavaFX Project on IntelliJ

I’ve had a hard time just to get a JavaFX project going with IntelliJ on Java 11. After spending 2 nights of digging and Googling, I finally got “Hello World” window to show up.

I will try to summarize what I have done.

Maven

I have decided to manage dependencies and build with maven. Here is the pom.xml file I created. Right click on the project in Project window and select All Frameworks Support to add Maven support to the project.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>groupId</groupId>
    <artifactId>jenkinstoolsetfx</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
            <version>11</version>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-fxml</artifactId>
            <version>11</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.8.1</version>
                <configuration>
                    <source>11</source>
                    <target>11</target>
                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

 

VM options

I’m sure the module path may be different depending your installation but here is the VM options I gave in Run/Debug Configurations. (Run -> Edit Configurations) This is necessary because JDK does not contain JavaFX by default anymore.

--module-path "/usr/share/openjfx/lib" --add-modules javafx.controls,javafx.fxml

Project

Navigate to File -> Project Structure -> Project. Make sure you select 11 – Local variable syntax for lambda parameters in Project language level.

Language Level

Navigate to File -> Project Structure -> Modules. Select 11 – Local variable syntax for lambda parameters for Language level in Sources tab.11 - Local variable syntax for lambda parameters

Target bytecode version

Navigate to File -> Settings -> Build, Execution, Deployment -> Compiler -> Java Compiler. Select 11 for Target bytecode version.

Recap

There are many options to create cross platform desktop applications and JavaFX is one of them. I hope JetBrain will streamline the way to create JavaFX project easily in the future. I have uploaded the code to my GitHub repository. https://github.com/hiriumi/jenkins-toolset-fx
