I installed Eclipse jee 2022-12 and then installed from the Marketplace e(fx)clipse 3.8.0. I am unable to create a JavaFX Main class. I use the package explorer and then New -> Other -> JavaFX -> Classes -> JavaFX Main class. When I press the Next button, nothing happens - the window where I could enter the name of the class is not displayed. I am using Windows 10 and I tried this on two different systems - with the same result. The same process works perfectly fine when using Eclipse jee 2022-09 Thanks Walter Taus

  • Can you create a normal main class extending `Application` and calling `Application.launch` in the main? Is there anything shown in the Error log view (`Window`>`Show View`>`Error Log`)? – dan1st Feb 11 '23 at 09:02
  • Sounds like the same cause as https://stackoverflow.com/questions/74758570/cant-create-new-fxml-file-in-eclipse/74758879, but there's no way to tell without the error log. – nitind Feb 12 '23 at 02:33
  • @nitind The error log shows: Unhandled event loop exception (org.eclipse.ui) – Walter Taus Feb 12 '23 at 10:23
  • @dan1st: creating a normal main class and turning it into extends Application does work without a problem – Walter Taus Feb 12 '23 at 10:26
  • Can you show the full stack trace from the error log? Until this problem is resolved, just work around it by creating a normal main class inheriting from `Application`. – dan1st Feb 12 '23 at 10:28
  • @nitind I just tried with Eclipse 2023-03 M2. The problem is still there – Walter Taus Feb 12 '23 at 10:45

  • That class [has been removed in 2022](https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Fguide%2Feditors_actions.htm&cp%3D2_0_13_8). Try updating e(fx)clipse if it is fixed on their side. – dan1st Feb 12 '23 at 14:43
