Read this section carefully; if you do not understand what it means, then get a knowledgable person who can help you to do it. Sdk mac: javafx-12-0-2-sdk-mac/ sdk linux: javafx-12-0-2-sdk-linux/. The Eclipse e(fx)clipse project provides tooling and runtime components that help developers create JavaFX applications. This project is part of Eclipse IDE 2018-12, Eclipse IDE 2018-09, Eclipse Photon, Eclipse Oxygen, Neon, and Mars. Download JavaFX Ensemble8 1.2 for Mac from our website for free. Our built-in antivirus scanned this Mac download and rated it as 100% safe. The software is included in Developer Tools. From the developer: Ensemble is a gallery of sample applications that demonstrate a large variety of JavaFX features. It is included in the official Oracle JDK. 3 JavaFX Installation for Mac OS X. This page provides information about the installing the JavaFX 2.2 SDK on Mac OS X. The JavaFX 2.2 SDK for Mac is installed as part of JDK 7 update 6 for Mac.

You do not have to install anything if you are working on a CS system in any of the ICLs. For these systems, refer to the Paths tables in this document when you need to locate a component.

Java and JavaFX

The version of Java is 12, and the environment needs to support the use of JavaFX.

Getting The Java Development System

Download the Java SDK (Software Development Kit) from https://www.oracle.com/technetwork/java/javase/downloads/. You have to accept the license.

Javafx 2.2 Download

Install it.

Download and Install the JavaFX Library Set

This section is a manual installation that requires understanding of the computer file system. Read this section carefully; if you do not understand what it means, then get a knowledgable person who can help you to do it.

Typically, you would download JavaFX from https://gluonhq.com/products/javafx/.However, JavaFX12 has been superceded by JavaFX13, and the links for getting JavaFX12 are below.

  • sdk windows: javafx-12-0-2-sdk-windows/
  • sdk mac: javafx-12-0-2-sdk-mac/
  • sdk linux: javafx-12-0-2-sdk-linux/

Create a system directory to store the library files or choose a directory in your own account, where you have permission to create a directory. This directory will contain your jfxdir directory.

If you are not sure where to create this directory, you might want to mimic the way that the RIT CS Department has configured its systems. See the JavaFX Paths table later in these instructions.

The rest of this document will use the name jfxdir as a placeholder for where you installed the JavaFX library files.

After you install the files into your jfxdir, navigate to the lib subdirectory, and move the src.zip file up one level out of lib. Your jfxdir content should then look somewhat like this in a file browser:

The lib folder above is the directory that contains the JavaFX jar files needed for compilation and runtime.

Command-Line Compilation and Execution
(Optional Extra Steps)

Enabling Command Line Execution

Javafx downloads

You can set up your PATH environment variable to include the JDK binaries directory. This step is optional but handy, because you may want to run the Java compiler or interpreter (virtual machine) from the command line.

If you have a Linux or MacOS computer, installing the JDK automatically sets the PATH so that you have access to Java command line tools.

If you have a Windows computer without the WSL (Windows Subsystem for Linux), or you did not install Java on that subsystem, you have to modify your PATH environment variable yourself. This shows you how to set up your WINDOWS PATH environment variable.

In a terminal window, make sure that these commands work and display the version of Java you expect (12.xx in fall 2019):

java -version
javac -version

To test your path setting on Windows, open a system terminal by searching for 'cmd' and starting the terminal application.

Command-Line Compilation and Execution

Throughout these instructions, the name jfxdir is a placeholder for the name of the directory (folder) where you installed the JavaFX library files.

If you are using the CS department computers, here is where you will find JavaFX already installed.

JavaFX Paths in the RIT CS Department Computers
Linux (ICL1, ICL2, queeg, glados)
/usr/local/dcs/javafx/lib/
MacOS (ICL5)
/Library/Java/Extensions/javafx/lib
(You may have to hit Command+Shift+G in the finder to see this directory. Or check the finder→Preferences:Sidebar:host disks checkbox.)
Windows (ICL6)
C:javafxjavafx-sdk-12.0.2javafx-sdk-12.0.2lib

Commands to Compile and Run from the Command Line

(For Windows systems, you must have set your PATH environment variable.)

The quotation marks are in case your full directory path includes spaces.

Configure IntelliJ IDEA

The IDE of choice is JetBrains' Configure IntelliJ IDEA. The Community Edition (CE) is free.

Install IntelliJ IDEA

  • Get a free student account for IntelliJ IDEA. If you don't already have one from having used PyCharm, go to https://www.jetbrains.com/shop/eform/students and sign up.
  • Download IntelliJ IDEA from https://www.jetbrains.com/idea/download/.
  • Install it.

Configure IntelliJ IDEA for Java and JavaFX

Run IntelliJ IDEA by finding and starting the application.

  • CS Department Linux computer: Open the Terminal application, and type the following into the terminal:
  • MacOS computer: Search for the application in Applications.
  • Windows computer: Search for the 'IJ' icon on the desktop.

The splash screen of IntelliJ IDEA has a Configure gear at the bottom. Click on the gear to configure default settings shown below.

  • Navigate from Configuration → Preferences:
    • Build, Execution, Deployment → Compiler → Java Compiler:
      • Select javac as the compiler.
      • Check the bytecode selection. If it says something that means 'same as language level', you can leave it as-is. Otherwise, try to set java bytecode version to 'same as language level' or version '12' if that is not available.
    • Click OK in the dialog.
  • Configuration → Project Structure for New Projects:
    • Project Tab:
      • SDK: 12
        (Search the file system for where you installed the JDK, or use the Java Paths table if on an RIT CS system.)
      • Language level: 12
    • SDKs Tab:
      • Use (+) to add 12 if not already shown.
        Use the JDK Home path folder icon to navigate if needed.
      • Select 12 for the JDK version.

        NOTE: Java should be installed in the standard location, and IntelliJ IDEA should find it. If IntelliJ IDEA tells you that it cannot find Java on your computer, then use a file browser to find the Java location; it may have been installed in another location.

    • Click OK in the dialog.

    If you are configuring IntelliJ IDEA on the RIT CS systems, search for libraries that are already installed. The Java Paths table below has the information.

    Java Paths in the RIT CS Department Computers

    Note: IntelliJ IDEA may already know where to find Java. Ask for help if the locations below do not work or you are having trouble following the paths below.

    Linux (ICL1, ICL2, queeg, glados)
    /usr/local/dcs/jdk/...
    where the ellipses(...) is the latest folder for Java version 12.
    MacOS (ICL5)
    /Library/Java/JavaVirtualMachines/jdk-12.0.2.jdk
    (You may have to hit Command+Shift+G in the finder Or check the finder→Preferences:Sidebar:host disks checkbox.)
    Windows (ICL6)
    C:javajava12jdk-12.0.2

    Creating an IntelliJ IDEA Project

    Do not put all of your assignments into one IntelliJ project. Make a new project for each one!

    These steps identify what you must do for every project that uses JavaFX.

    Choose Create New Project from the initial screen.

    In the dialog that pops up, make sure that the plain Java(not JavaFX) is selected on the left, and the Project SDK is the version of Java you downloaded. Change the SDK to the right version, or add a new version if needed.

    Hit Next, but do not check any templates.

    Hit Next, and choose a project name. If you are doing this for the first time to test everything, make a project called 'Lab00'.

    Before you close the dialog window, check the directory path. The default is fine unless you are on a Windows systems in ICL6.

    For Windows systems in ICL6, change the directory path so that it uses the Z: drive where your RIT CS account is located. The default location is ideaProjects.

    Add the name of your project to the end of the directory path if it is not already there. Advice: Never change the lowest level directory name. The last part of the directory name must match your project name.

    About the IntelliJ IDEA Layout

    Various tabs show up along the left, bottom, and right margins. They may not work the way you expect. If the pane associated with a tab is not showing and you click the tab, the pane will appear. If the pane is already showing, clicking the tab will make it disappear.

    Folders are opened by double-clicking or by clicking the small triangles or arrows to the left of their names.

    Open the Project pane using the tab on the left. You will see several main folders. One folder, named for your project, will eventually contain the source code for your assignment.

    Within the new project, start at the File menu:

    File→Project Structure
    Project Settings→Libraries

    Shows you an empty window pane on the right. Hit the + button at the top, choose Java.

    Navigate to find the jfxdir/lib folder; choose the lib folder, and not its contents.

    When finished, you should see entries in the pane corresponding to the directory chosen. IntelliJ IDEA should tell you the library has been added to the Lab00 module.

    To make sure the libraries were added, click Modules on the left hand side, and choose the Dependencies tab near the upper right. You should see your JavaFX directory listed there.

    If it says 'Compile' next to the directory, click on Compile and change it to 'Provided' and apply the change.

    Click on the OK button in the project structure dialog to return to the main window.

    If you are on a Windows system in ICL6, IntelliJ will complain about delays due to networking to your Z: remote mount. You can ignore the popup warnings by closing them, but you may experience intermittent network delays during compilation and execution.

    Adding Java Sources to the JavaFX IntelliJ IDEA Project

    To validate the Java and JavaFX installation with IntelliJ, you have to:

    • create a package;
    • create a class for the application main in that package; and
    • create a module-info.java to identify which Java runtime modules are required to run the program.

    If not already opened, open the Project tab on the left edge of the tool window.

    Open the directory for the project ('Lab00' for this example). The figure shows the project folder already opened. You should see a src folder.

    Create something called a package for our Java source code. (Although it is possible to write code outside of any package, it is not recommended, and some tools and libraries don't work well with code not assigned to a package.)

    Right-click on the src folder and select New→Package to create the lab00 package. A new folder called lab00 appears under the src folder.

    Right-click on the lab00 folder, select New→Java Class and enter HelloFX to create a file named HelloFX.java under the lab00 package(folder). An icon appears in the src folder, and a text edit window opens for it.

    Erase all the code in the new file.

    Paste the code below into the file, replacing all text the tool placed in there:

    Creating the module-info.java file

    Right-click on the src folder, and choose New→module-info.java.

    A new file by that name appears in the src folder, and IntelliJ IDEA opens a text edit window for it.

    Paste the following code into the edit window, replacing all text already placed there:

    The name exported must match the package name you created. It is also case-sensitive.

    Save the files using the File menu or using control-s (command-s on MacOS).

    Now use the Build menu to compile the program. The Messages tab will display output of the build, and it should report no errors or warnings.

    Note that, javac in MacOS warns that the package name should not have trailing numeric digits. You can ignore this warning.

    Running the program in IntelliJ IDEA

    You need a run configuration to run your program.

    There is a small button, or pull-down menu to the left of a green 'run' triangle at the top of the tool window, that will be labeled with Add Configuration. Click it. If something else appears in that menu, click and choose Edit Configurations... from the list.

    In the dialog, click '+' to make a new configuration. Select Application from the list. If there was already a run configuration there, you could copy or edit that one instead.

    Choose an informative name. In the future, you may have more than one run configuration for a project.

    Set the Main class. For this example, the main class is lab00.HelloFX.

    Do not enter 'HelloFX.java' or 'lab00/HelloFX.class' for the main class; it will not work.

    Check the box to 'include dependencies with 'Provided' scope'. Without this, the configuration will not find javaFX.

    Click 'OK'.

    The name of the configuration should now show in the button that used to say 'Add Configuration'. (In the future, you can click the adjacent pull-down menu and select 'Edit Configurations' to add, remove, or change run configurations.)

    Click green triangle 'run' button to the right of your HelloFX run configuration name.

    If everything is correct, your program should compile and a large window should pop up that displays the version of Java you are running. If this does not happen, seek help.

    You should also see that the program is running by the fact that the small square at the top of the tool window has turned red. (Clicking that square when it is red is an emergency way to stop your program.)

    Hit the app-closing button found in the frame of the window. (It is a red 'X' in a square or a red dot.)

    The program should terminate, and the tool's square's red color should go away again.
