Javafx runtime components are missing and are required to run this application что делать
Здравствуйте, столкнулся с данной ошибкой не понимаю почему.
На фотке прикрепил всю структуру проекта и главный класс.
Дело все в том, что в IntellijIDEA все компилируется, но когда создаю jar файл через меню File->Project Structure -> Artifacts ->new Jar File. А потом запускаю его через cmd командой java -jar [абсолютный путь до jar файла], то вылетает данная ошибка. Были подозрения на модули проекта (прочитал советы в интернете), но они у меня прописаны в module-info.java. Фотку также прикрепил. Куда копать не знаю, если прописываю модули в ручную в меню Run -> Edit Configurations -> VM options, то он перестает видеть мой "module org.diploms" ,подскажите что делать копаюсь сутки.

Ответ очень оказался прост, почитав документацию JB он нашелся. На картинке сказано "Упаковка приложения JavaFX в .jar это возможно только с Java 8." Поэтому переводите свои проекты на Jdk-8, отмечу что это последняя версия в которой включена поддержка JavaFx (т.е. вам не придется тянуть зависимости maven или подключать модули библиотеки вручную. Все классы JavaFX включены в стандартный jdk, достаточно сделать import.

I should add that you can also go directly to the Gluon JavaFX page, which will point you to the instructions for using the JavaFX maven modules.
I'm getting the same error when using the maven module, but I suspect it is due to Eclipse. It should work with OpenJDK 10 right? or do I need to use OpenJDK 11?

I managed to solve it by adding a module-info.java file (I'm new to java), sorry for the noise :)

Solution 1: Follow this step
- First of all Go To File.
- Then Select Project Structure.
- Now, Select Modules.
- Then tap on Dependency.
- Now, Click on + (on left-side of window).
- clicking the “+” sign will let you designate the directory where you have unpacked JavaFX’s “lib” folder.
- Scope is Compile (which is the default.) You can then edit this to call it JavaFX by double-clicking on the line.
- Then, Select Run.
- Edit Configurations
- Add this line to VM Options
- –module-path /path/to/JavaFX/lib –add-modules=javafx.controls
- And don’t forget to set the SDK
- Now your error will solved.

@Aaris-Kazi, I was also facing the same issue and it can be resolved by adding vmArgs in the launch.json file
"vmArgs": "--module-path \"C:\\Program Files\\Java\\javafx-sdk-11.0.2\\lib\" --add-modules javafx.controls,javafx.fxml"
If you’re not familiar with Java modules, you’re almost guaranteed to get hit with an error: “Runtime Components Are Missing”. It can be a huge frustration if you’re trying to get into JavaFX. Even if you consider yourself to be pretty Java-savvy.
One side effect of Oracle removing JavaFX from the JDK was to make it harder to get started. Honestly, JavaFX should be a very intuitive and easy to use piece of software. But this is one of the few awkward stumbling blocks that trips a lot of people up.
A “Runtime Components are Missing” error is generated by the Java Launcher. It is generated for all non-modular JavaFX projects since Java SE 9. However, it can be corrected by adding JavaFX modules, using command line arguments.
When I first came back to JavaFX after using it in Java 8, every single one of my old prototypes crashed. So if you’ve had this error don’t be disheartened. It’s a relatively easy fix.
How we’re going to fix it
The good news is there are several easy ways to fix your app. Generally, there are two situations you could be in to find this error.
- You’re in an IDE and when you hit ‘Run’ the IDE delivers the error
- You’ve got a JavaFX application packaged as a jar. It won’t run, but you’re smart enough to run it from the command line. Low and behold… error.
The solutions in each case can be similar, although if you can’t make your app modular you will have to apply command-line arguments both in the IDE and with your Jar.
I’ll start with launching from the IDE, because that seems natural. If you’ve got a Jar that won’t run, feel free to skip on down.
I’ll talk a little about why this is happening, because it has to do with JavaFX’s custom windowing and rendering systems. But, I completely understand if you just need those fixes, you can skip ahead to there too.
Fixing Runtime Components in the short term
This is a wildly irresponsible cowboy fix, but if you’re not looking to a long-term stable project (for example university projects or prototyping), it can be a good way to get around the issue for now.
To jury-rig the Java launch process and fool the LauncherHelper into not realising your app is an instance of a JavaFX Application, you can create a dummy class to act as an entry point to the program.
In this case, we’ll set MyLauncher as the main class for the application and the only responsibility of this class will be to launch our actual application!
The benefit of this fix is that it will get rid of this error in both the IDE and with a packaged Jar. That being said, I’d really recommend checking out some of the more sustainable fixes below.
Especially in the case of an app you want to deploy in a production environment, you’ll have a much bigger job changing your application when it’s already in production.
If you’re curious as to why JavaFX needs to check that the runtime components are present, check out the drop-down below.
Why JavaFX needs ‘Runtime Components’
Java has other windowing solutions that don’t need this custom support, so why does JavaFX? Well, the Abstract Window Toolkit (AWT) has been with Java since the beginning. In that sense, it’s baked into the Java runtime. Swing, which also provides a GUI framework, is sat on top of AWT.
Swing, JavaFX uses its own custom windowing toolkit – glass – which is used in combination with prism, its graphics engine. Both of these are inside the javafx.graphics module. When JavaFX was added, the Java launcher was modified to allow JavaFX to set itself up before the application launched.
This is done inside a class called LauncherHelper, which is called whenever any class or jar is run.
As with everything in Java, it also makes sense to delegate where you can. So, when an application is launched, LauncherHelper checks whether it’s a JavaFX program, and if it is, it hands off the responsibilities to the FXLauncher , which runs some pre-flight checks and sets itself up ready to run.
In fact, the main class that the FXLauncher launches isn’t the main class of your application. In this case, FXHelper does the any setup needed before checking back in with our app.
One fix I’ll go through today short-circuits this test by jury-rigging the launch process to fool Java into thinking it’s not a JavaFX application. For small projects, that’s OK, but if you’re looking at developing a production-level or portfolio app, there are other, more sensible ways to do this.
If you’re looking for a really fast fix, though, it does the job.
Fixing JavaFX Runtime Components Issues Responsibly
A lot of these fixes aren’t a lot harder than the cowboy fix above, but they do take a little bit of understanding, or a tiny bit of patience.
in the first case, converting to modules takes a litte bit of understanding. But it’s a fix that will work in both the IDE and the Jar. If you choose to provide VM arguments manually, you’re going to need to provide these to run the Jar too – hence the patience.
1. Make your app modular
By far and away the most future-proof way to fix this error is to convert your project over to a modular one. That being said, it’s not always practical. There are plenty of libraries that currently don’t fully support java 9 modules (Apache POI is a great example)
It can also be a little intimidating if you haven’t migrated yourself across to modular projects yet.
Why convert to Modular
From Java 9 and onwards, Java has modularized. In part, it’s to give you flexibility to add modules easily to your runtime image without including a bunch of jars. But in part it’s because Oracle can no longer assume that Java will exist on every machine you might ship your code to.
A few years ago, when Java aggressively pushed the JRE with manufacturers, it was a safe bet that a JRE existed on most machines. But, nowadays this just isn’t the case. So, developers find themselves shipping their program (which might be quite small) with a 200 MB JRE.
With Java modules, you can include just the modules you need, to make a custom JRE of a much smaller size.
The price you pay for shedding up to 150 MB off the program you’ll eventually ship is that you need to specify which modules your program requires. If there isn’t an overwhelming reason why you need to stay pre-modular, I would suggest the a few lines of code (5 in this case) is more than worth it.
1. Getting access to other modules
- Whenever you want to include a module in your program, you need to use the requires keyword
Some modules use the transitive keyword to specify modules that they need, but also that you have access to as well! A good example of this is the javafx.controls module, which requires transitive javafx.graphics and javafx.base . That means your program can access javafx.graphics and javafx.base but you don’t need to include module statements for them.
If course, if you’re not using a build framework, you will still need to download the javafx.graphics and javafx.base jars or jmods for your program to work.
2. Giving reflective access to your module
- We need to give javafx.graphics reflective access.
The JavaFX graphics module injects fields into a Controller using reflection. This is useful, because it facilitates dependency injection, but it means we need to grant reflective access. That requires the opens keyword.
3. Giving other access to your module
- Part of the process of launching our app is to allow JavaFX to set up quickly int he background and then call our main class when it’s ready. To allow this, we need the exports keyword.
Part of that process is that the FXLauncher operates on our main class in order to launch it (check out “Why JavaFX needs Runtime Components” in the dropdown above), we need to allow that too.
3. Putting it all together
All-in-all, our module-info.java file should be in the root of our project directory and for a module called my.project , should look like this:
That’s all we need. If you want more detail on adding modules to a project, check out my post on setting up a modular project with Maven.
Honestly, Java’s module system means that Java is now purpose-built to do things like add in JavaFX. For me this is the logical way to fix the project.
2. Add command-line arguments to your app
This is a pretty flexible fix, which can be done in any IDE. The caveat is that you’ll also need to provide the same arguments when running your Jar. For this to work, you’ll need to know the location of the JavaFX SDK you’ve downloaded on your machine.
I’ll go through what the parameters are first, then how to add them to your IDE. Finally, we’ll cover how to add these arguments when running your jar.
The module parameters you need to add
To fix this, we’re going to pass two sets of parameters to Java as we run our code.
1. Module Path
The first is --module-path , which is going to specify the location in our filesystem where the JavaFX jars are located. Regardless of where you’ve located it, you need to provide the address to the lib folder (this is where the jars are stored).
2. Modules to add
The second argument is --add-modules . This will define which modules to add to our project. For the simplest project, you’ll just need javafx.graphics . However, the basic use-case of an app with buttons (controls), FXML files and so on will require we include javafx.controls and javafx.fxml . Include these separated by a comma but no space.
Make sure you leave a space between the --module-path arguments and the --add-modules arguments or you’ll continue to see errors..
Next, we’ll add them into the IDE run configuration.
Adding VM arguments in an IDE
The most popular are Eclipse and IntelliJ, so I’ll include some screenshots here, but this should work no matter which environment you’re developing in.
a. Eclipse
To add VM arguments in Eclipse, right click the project. Click Run as then Run Configurations . Head to the the Arguments tab and you’ll want the VM Arguments box (not the program arguments one).
b. IntelliJ
In IntelliJ, click the drop-down to the left of the run button, or in the menu bar, Run -> Edit Configurations . In the right-hand panel of your run configuration, specify your main class, and add VM options in the box below.
And that’s it! Your program should run in the IDE.
Adding VM arguments to a Jar
If dependencies or project-constraints are stopping you from converting your project to a modular structure and rebuilding your Jar, you can still run your jar using a batch (or shell) script providing the runtime arguments to the launcher.
Batch scripts allow you to save executable commands into a plain text file to run later. What we’ll save is a combination of the java command to launch a jar ( java -jar myJar.jar ) with the arguments needed to specify the runtime components. So in each case, our script will run:
If you don’t know how to create these files, here’s how. I’ll run through how to create both batch and shell scripts on Windows and Mac/Unix systems. In either case, we’ll be running the same command.
1. Creating a batch file
In Windows, create a file labelled launcher.bat in the same directory as your Jar file. Right click and select “edit” to edit your file.
Add the text, editing your module path so it points to the lib folder of the JavaFX SDK you have on your system, and save. 👍
To launch your application, simply double-click the script file, or launch it from the terminal.
2. Creating a shell file
In Linux or on Mac, launch the terminal and navigate to the folder with your jar, and create a file using the command "touch launchScript “.
Using your favourite text editor, we’ll need to add two commands to the file. The first directs the system to run launchScript as a shell script, and the second runs our app with the VM arguments.
Again, edit your module path so it points to the lib folder of the JavaFX SDK you have on your system, and save. In the same way as with Windows, to launch your application, simply double-click the script file, or launch it from the terminal.
A “Runtime Components are Missing” error is generated by the Java launcher if JavaFX is unable to set up ahead of launching your app. This is required by the Java Launcher, which requires JavaFX to be on the module path in order to confirm the runtime requirements are met prior to launching.
We can solve this error by modifying our project to make it modular, and adding the correct JavaFX modules. However, if project constraints prevent you from modularising your project, these arguments can also be provided manually.
Inside an IDE, arguments can be passed to the virtual machine through the VM options settings in Run Configurations. Once packaged as a Jar, these settings much be set manually each time we want to launch the Jar. This can be automated by creating script files that are responsible for launching our app.
Hello Guys, How are you all? Hope You all Are Fine. Today I am trying to run my javaFX project and I am facing following error Error: JavaFX runtime components are missing, and are required to run this application in Java. So Here I am Explain to you all the possible solutions here.

Как первый пользователь, мне удалось заставить его работать, но для меня это было непросто.
Думаю, мало кто знаком с этой IDE, поэтому я опубликую шаги, которые я выполнил, в качестве базового руководства:
Загрузите и установите версию jGRASP 2.0.5_05 Бета.
Поскольку у меня установлено несколько JDK, он по умолчанию выбрал JDK 10.0.2, поэтому моим первым шагом было найти способ работы с JDK 11. Это можно сделать в Settings -> jGrasp Startup Settings , где я могу указать путь для мой исполняемый файл java :
Затем я перезапустил jGrasp. Вы можете проверить, какой JDK использует IDE в Tools -> System Info -> Java Version .
Откройте образец класса HelloFX. Я начал с самого простого примера из документации OpenJFX. Код можно найти здесь.
Build -> compile , как и ожидалось, вызовет кучу ошибок, учитывая, что JavaFX больше не является частью JDK:
Следуя документации OpenJFX, нам необходимо загрузить JavaFX SDK с здесь, а затем добавить библиотеку в путь к классам. Перейдите к Settings -> PATH/CLASSPATH -> Workspace , нажмите "Создать" и по очереди добавьте разные jar-файлы JavaFX из загруженной папки SDK / lib (как минимум javafx-base.jar , javafx-graphics.jar и javafx-controls.jar ) ,
Build -> compile теперь должен работать.
Следующий шаг: Build -> Run . Это не удается:
Это было ожидаемо. Согласно документации, нам нужно установить аргументы module-path и add-modules.
- Первая попытка: используйте Run arguments . После установки:
Что случилось с этим!? Что ж . если вы попробуете это в командной строке, это тоже не удастся, потому что порядок аргументов неправильный, аргументы vm должны идти перед именем класса.
В заключение: Run arguments не VM arguments !
- Вторая попытка: чтобы предоставить аргументы виртуальной машины, я нашел вариант отредактировать Settings -> Compiler settings -> Workspace . По умолчанию он использует jdk (integrated debugger) - generic . Вы можете просмотреть его и увидеть, что для Run он использует:
Поэтому вместо ARGS нам нужно найти способ установить FLAGS2 .
К счастью, рядом с вкладкой Environment есть вкладка Flags/Args , и там мы можем установить наши аргументы vm в FLAGS2 :
- Примените, закройте диалог и Build -> Run класс, теперь он будет работать!
Если вы видите журнал консоли, он содержит именно ту команду, которую вы использовали бы при запуске в командной строке:
Думаю, следующим шагом будет запуск более сложного проекта .
Попробуйте просто создать средство запуска только с основным методом. Это может выглядеть примерно так:
(вы можете пока оставить старый основной метод неиспользованным в вашем приложении)
У меня это сработало с JDK 13, JavaFX 13 и Eclipse 2019-12 под Ubuntu.
(Я создал проект, используя «new / Maven Project / Simple Project», а затем просто добавил JavaFX, Logging и другие вещи в качестве зависимостей в pom.xml, которые все попали в Classpath. Только JDK был в Modulepath) > Не нужно беспокоиться о модулях Java.
Если это сработает, вы можете потратить время на то, чтобы узнать о модуляризации Java в другой день .
. и не забудьте проголосовать за этот ответ. :-)
