Hi,
I was using as target platform Eclipse Modeling 2018-09 + EFX 3.6.2.
==> no problem.

When trying to move on Eclipse Modeling 2020-03 + EFX 3.6.2 when starting the application I got a noSuchMethodError see below.

Which latest version of Eclipse runtime, EFX 3.6.2 is compatible with please ?

Thanks for your help.
Stéphane.

Here is the stack trace:
java.lang.NoSuchMethodError: org.eclipse.e4.ui.internal.workbench.ReflectionContributionFactory.<init>(Lorg/eclipse/core/runtime/IExtensionRegistry;)V

3.6.x is built against a fairly old target platform, we don't upgrade our target platform frequently because we got tired to hunt regressions introduced by the platform team and yes we need to use internal APIs there was/is no way around that. Anyways the current nightly builds run against 2019-12 so you should be able to update to the nightly target

Final note the current nightly is going to be what we'll releasing in the next few weeks.

Thanks a lot Tom, it is crystal clear, I'm with you ;D

Same philo to me regarding upgrading a target platform.
I used to run against 2014 Modeling SR1, then 2016 Modeling SR1.
After 4 years, I'm upgrading again: platform, EMF, EFX and CDO.
To get something stable without regressions as you said it could be quite challenging, that why I try to be up-to-date as maximum to have a good ROI of the effort of moving on.

2019-12 with NB builds is perfect for my needs
