JavaFX and IntelliJ no errors althought the documentation says I should have some

Asked 2022-Jan-31 at 06:30

I'm currently following this tutorial: https://openjfx.io/openjfx-docs/ (JavaFX and IntelliJ IDEA). I use Intellij 2021.3.2.

I have created a project (1. Create a JavaFX project), which worked out great and didn't need to 2. Set JDK 16 because it was already set to 17 (which I guess is fine).

But here begin the weird stuff (and I'm very new to programming so I'm sorry if it sounds silly). "You can also set the language level to 11 or greater." I don't have this option. Because it's "can" I felt like it wasn't a big deal but if someone can explain what this is all about? Just out of curiosity, because I'm at the very beginning of the tutorial and I kinda only understand half of it.

Then 3. Create a library, and I don't have what they have, and my stuff is red:

So when they said "add the JavaFX 17 SDK as a library to the project" I didn't know what to do. I also didn't know what to do to fix the red stuff.

And finally, they say "Warning: If you run now the project it will compile but you will get this error: ..." but if I click on this button

everything works! which you know i'm not complaining about but I would like to understand a bit more what is happening.

And then they suggest I should 4. Add VM options to fix the problem that I don't have. So I figured maybe my computer set the VM options correctly without me knowing it but there is currently no VM option (and it works). Should I add them nonetheless?

Thank you for your help, I'm very lost and feel like I don't really understand anything.

The current documentation in the openjfx tutorial for getting started with JavaFX using Idea is incorrect, at least for recent Idea releases (2021.3 +).

The tutorial is written as though a new Java project was created, rather than a new JavaFX project. Once a new JavaFX project has been created, most of the rest of the steps in the tutorial are either redundant or wrong.

Step 1, “Create a JavaFX project", does a lot more than just “Create a Java project”, which is why everything else is different from the tutorial.

A better tutorial for getting started with JavaFX with Idea, is the official Idea documentation:

Create a new JavaFX project.

Differences between creating a new Java project and creating a new JavaFX project

The new JavaFX project:

Provides a build script for Maven (pom.xml) or Gradle (build.gradle).
Adds the appropriate dependencies for JavaFX base, graphics, controls and fxml.
Provides an example application and controller code that you can run immediately.
The example project is modular and provides a module-info.java
Because the program is modular and dependencies are downloaded via maven and recognized by the IDE, you don’t need to manually configure VM runtime options for the module path and adding modules.
Idea will recognize the Maven or Gradle projects and automatically synchronize the initial transitive dependent libraries with the Idea project.
There are options in the Idea Maven tool window which will allow you to synchronize further changes to dependent libraries or javadoc and source code in libraries.
Selects a JDK and attaches it to the project, automatically downloading the selected JDK version if not already present.
Sets an appropriate language level for the project.

When you just use the create new Java Project option, it doesn’t do any of those things, so you need to do things manually instead, which is what the rest of that tutorial is about:

Manually download the JDK and configure it in the SDK.
Manually download the JavaFX SDK and add the libraries from it to your project.
Manually configure VM modular arguments.
Manually maintain any other dependencies.
Manually associate javadoc and source code.
Manually write the code for a basic application.
Manually set the project language level.

Doing all this stuff manually is more work and more error prone. The manual work usually leads to a worse outcome and a project that is more difficult to maintain for many people getting started with JavaFX, so I do not recommend it.

Versions

In terms of the versions to use, I recommend using the most recent stable (non-beta) releases of both JDK and JavaFX, regardless of what versions may be referenced in any tutorials you may be using.

You can set JavaFX versions in the Maven file generated by the new JavaFX project wizard, then press the button in the Maven Tool window to synchronize the Maven project with the Idea project.

Language level settings

These are important later on, but pretty irrelevant when just getting started.

The language level settings:

Tell the compiler what version of the java byte code to compile the application to.
Tell the IDE what language syntax rules to enforce and provide help with.

If you use Java 17 only features, the app won’t run on a Java 11 VM.

You can define the settings in Idea manually:

language setting level.

But it is better to set them in the compiler section of the maven project and synchronize the project with Idea, which will also configure the settings in the IDE.

IMO, set it to the most recent stable version and have a requirement that your application be run with that Java version as a minimum (you can enforce that by using jlink or jpackage to bundle the JRE version you choose with your packaged app).

QUESTION

How do I find the most recent version of JavaFX to implement in my build.gradle file?

Asked 2021-Nov-28 at 22:46

What I believe is the official website, openjfx.io, tells me to use version 0.0.10 in gradle. However, It's incompatible with JDK 8 and 17, spitting out java.lang.UnsupportedClassVersionError: org/openjfx/gradle/JavaFXPlugin has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0 I looked through the JavaFX repo, but couldnt find a good version number to replace 0.0.10 with, but I don't think 0.0.10 is really the most recent one. Where can I find the most recent build number?

...

ANSWER

Answered 2021-Nov-28 at 22:46

tl;dr

Currently the latest versions for JavaFX development would be:

JavaFX Gradle Plugin 0.0.10 (simplifies working with JavaFX 11+ in Gradle projects)
OpenJFX 17.0.1 (libraries that implement JavaFX, require Java 11 or later)
Java 17.0.1 (an LTS version)

JavaFX Gradle Plugin

Comments by Slaw point out that you seem to be confusing the Gradle plug-in for JavaFX with the OpenJFX libraries needed to run a JavaFX app.

The plug-in simplifies working with JavaFX 11+ for Gradle projects.

Currently, that plugin’s latest version is 0.0.10. See also the GitHub product page.

OpenJFX libraries

As for the OpenJFX libraries, see the Products Roadmap at GluonHQ.com. You will find 17.0.1 is the latest, with 18 in early-access.

The JavaFX (OpenJFX) releases have been synced to arrive at about the same time as the Java releases, and use the same major version number. A convenient approach.

But OpenJFX releases do not require the latest Java. The Release Notes for 17 says it requires Java 11 or later. Note that both Java 11 and 17 are Long-Term Support (LTS) versions.

I suggest you generally do your development work with the latest Java and the latest JavaFX while aiming your deployments at the latest LTS version of both. Note that Oracle recently announced a change in the LTS cadence from every three years to every two years. Presumably JavaFX will follow that as well.

IntelliJ doesn't make it all that easy to use JavaFX. I find the most intuitive way is to do the following:

Add global libraries for the JavaFX modules you want to use. The easiest way is to use from Maven and search for org.openjfx then add the modules you want (e.g. controls and fxml for the basic IntelliJ generated JavaFX project).
Create a module-info.java file for your app that looks something like the code below.

One of the comments here mentioned that they'd put their .jar in the mods/production folder. I did the same... and it worked. (╯°□°）╯︵ ┻━┻

I guess "Modular from IDE" doesn't agree with the IDE.

Looks like the proper way to go about modular is to use Maven/Gradle. I'll rebuild and go with Gradle.

This problem is caused by the fact that you try to call showAndWait() on a stage that is already visible. From the javadocs

Throws: IllegalStateException - if this stage is already showing.

If you delete the initial call a.show(); this should fix your problem.

The javafx.fxml module instantiates controller classes, and accesses fields and methods in them, via reflection. In order for that to work, you need to open the specific package(s) containing any controllers to the javafx.fxml module.

This is a good resource for understanding the module system. Quoting from it:

open, opens, and opens…to. Before Java 9, reflection could be used to learn about all types in a package and all members of a type—even its private members—whether you wanted to allow this capability or not. Thus, nothing was truly encapsulated.

A key motivation of the module system is strong encapsulation. By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

JavaFX, JLink/JPackage Module issue - adding Libraries "Error occurred during initialization of boot layer java.lang.module.FindException"

Asked 2020-Jun-02 at 10:19

IDE: IntelliJ. Trying to use JavaFX for the first time with some additional libraries, and with an installable package - (c/o JLink/JPackage) Have followed directions from OpenJFX for a Modular Project from IDE and can get this to work no problem. https://openjfx.io/openjfx-docs/

Adding libraries though I am just getting this error: "Error occurred during initialization of boot layer java.lang.module.FindException: Module eu.hansolo.medusa not found, required by ModuleName"

Have read a number of similar threads on this error but no joy here specifically.

Have tried adding adding to VM on run configuration ie:
--module-path ${PATH_TO_FX}:mods/production --add-modules javafx.controls,javafx.fxml,eu.hansolo.medusa -
still getting "Error occurred during initialization of boot layer java.lang.module.FindException: Module eu.hansolo.medusa not found"

However.. If I delete the "module-info.java" file.. I can run the application in IntelliJ no problem.. however.. I then can't use JLink to make the custom runtime image.

Any advice or pointers to reading I can do would be greatly appreciated and many thanks in advance.

So the issue appears to be that you haven't added Medusa to your module path. The way I accomplished this is by using maven.

I added the dependencies to my pom file and created a module-info.java and everything seemed to work.
