Eclipse User

Hello,

I am trying to run GEF examples as it is written here: https://github.com/eclipse/gef/blob/master/README.md#eclipse-graphical-editing-framework-gef

I comleted steps:
Set up an Eclipse IDE (using OpenJDK 11 and OpenJFX 11)
- I am using JDK 19.0.1, OpenJFX 19
Set up a Target Definition containing GEF
- I got some missing dependencies here, viz dep.jpg - I don't understand why

but when I tried to Run the examples I got this error:

!SESSION Sun Dec 11 14:50:07 CET 2022 ------------------------------------------

at org.eclipse.equinox.launcher.Main.main(Main.java:1440)

I think I did everything from manual.. can someone help me to get through this?

I should add that I am using latest Eclipse for Committers.

Thank you very much.

I managed to fix the missing dependencies, by changing https://download.eclipse.org/releases/2019-03 to https://download.eclipse.org/releases/2022-12. But I am still left with the last error java.lang.ClassNotFoundException: org.eclipse.core.runtime.adaptor.EclipseStarter
