Hi every one:

I installed e(fx)clipse on my eclipse 2019-09 using the Tom's tutorial, but it seems doesn't work well.

1.- The JavaFX SDK library doesn't have any effect on the project classpath.
2.- The CSS editor not show the auto-complete menu for "-fx-" properties.

I'd tried using java11, 12, 13 but without luck.

I tell your worse, if I set jre8 like default, it works perfectly, but who is using java 8 yet? ....

any advice for this poor confused programmer?

Thx

On classpath/compilation:
* So the tutorial i wrote for PDE based OSGi-Applications are we talking about that (I doubt because you talk ab JavaFX SDK library)
* If we talk about plain old java projects I highly recommend to use maven or gradle everything else is not really a feasable way forward

On CSS-Editor:
* Yeah we need to find a way to get the correct cssext-File on the classpath but I have not really a good idea how this could should work with maven/gradle

I too am having this issue. What if we do not want to use Maven or Gradle? After all the JavaFX SDK is installed on our very machine and therefore Maven and Gradle should rightly be unnecessary. I hate to have to install extra things because your plug-in has not been updated to work smoothly on its own with any Java FX SDK beyond 8. Please make fixing this your topE(FX)Clipse project priority. I guarantee you there is probably many more of us with this issue not reporting it and migrating to Intelli-J.

I think the issue is of enough importance that it will negatively affect not only the adoption of E(FX)Clipse, but also the use of Eclipse as a whole for the development of a modern Java graphical user interfaces.

Hi guys, I also had a problem with e(fx)clipse in Eclipse - because there is many solutions in the Internet (some of them work, some of them not) I want to share a my solution. It is based on the installaton guides that I found in Google, but most importantly that it works.

IMPORTANT: this instruction working for sure with Eclipse EE 2020-03 and JDK13 (during my search for answers I was deperate to find the solution, that I have installed many versions of Eclipse: 2019-09, 2019-03, even Oxygen. Finally I've installed 2020-03 EE, and because instruction below worked, I have not tested it on other versions of Eclipse - but I hope it works too.

1. Install e(fx)clipse according to this web page: https://www.eclipse.org/efxclipse/install.html#for-the-ambitious

a) in "Install new software" wizzard you should add the new site location to found proper software. Use "Add" button in "name" section type "e(fx)clipse (or anything you want, it does not matter). In "location" section type: https://download.eclipse.org/efxclipse/updates-nightly/site/
b) after using search button you should found two applications: e(fx)clipse-install and e(fx)clipse - single components - install them all
c) after intallation Eclipse will restart

2. Download Java FX from: gluonhq.com/products/javafx/ (I have used JFX14)

3. Extract downloaded pack and REMEBER THE LOCATION OF EXTRACTED FILES (it is very important).

4. In Eclipse run Window -> Preferences -> Java -> Build Path -> User Libraries. Click "Add" and name it "JavaFX14" (or whatever you like).

5. One-click on the newly added library, and click "Add external Jars". Find the files that you downloaded (that from step 3) and find folder named "lib" (in my case was "C:\Java\openjfx-14_windows-x64_bin-sdk\javafx-sdk-14\lib). Select all JAR files (in folder should be JAR files and one ZIP Archiwe so watch out).

6. Click Apply and close.

7. Run Window -> Preferences -> Java -> Installed JRE's. Click on the your active JDK and click "Edit" button.

8. In "Default VM arguments" section type:
--module-path [LOCATION OF THE DOWNLOADED FILES FROM STEP 3]\lib --add-modules=ALL-MODULE-PATH

In my case it was: --module-path C:\Java\openjfx-14_windows-x64_bin-sdk\lib --add-modules=ALL-MODULE-PATH

Notice that location address leads to "lib" folder - do not forget it!

9. Done!

Now when you will create a new Java Project (classic Java Project, not FX or something) you must remember only one thing. After setting project name, location etc. do not click "Finish" button. Click "Next" button. Click on "Libraries" bookmark, then ONE-CLICK ON THE MODULEPATH (it is very important). Now click "Add library" / User libraries and choose previously created library. It should appear your library on the list of modulespath. Click Finish and enjoy of your project with JavaFX. This step should be repeated every time when you want to create a new java project. But inside the project you don't need to do anything. You can add a classes, interfaces etc. and testing it by "Run button" (no Run configuration or something!)

PS. Sorry for my english - still learning.

I fully understand your frustration but:
* efxclipse-ide is a part time project (mostly unpaid)
* the adviced & documented way to use JavaFX-11+ is to use maven/gradle as it is not part of the JDK anymore and should be treated as any other library - for eclipse that means you need to have m2e installed

I'm swapped with other work so I can not promise to get that fixed very soon. If there's no ticket yet filed on github (https://github.com/eclipse-efx/efxclipse-eclipse/issues) please at least file one, I promise that the next time I have time to investigate e(fx)clipse IDE issues I take a look. BTW: I doubt that you can use JavaFX11+ on IntelliJ without maven/gradle but I could be completely wrong.
