I keep getting a repository is not found, seems like GMF tooling is removed?

Yes, this seems to be the case. I've added a request to keep the GMF Tooling update site despite terminating the project here: https://gitlab.eclipse.org/eclipsefdn/emo-team/emo/-/issues/593

In the meantime, you can install Epsilon from its update site if you omit the Epsilon GMF Integration feature.

Hi there, thanks for your quick response. It's actually the GMF Integration that I need for Eugenia.

Until this gets fixed, I've added a warning to the download page.

We've had to remove Eugenia itself from Epsilon, as the GMF Tooling update site is no longer available, which was also breaking our continuous integration builds.

We're waiting to see the response from the termination review issue, with the intent to provide some mechanism to make it possible to install older versions of Epsilon with Eugenia in compatible Eclipse releases (before 2022).

The GMF Tooling update site has been temporarily restored until a longer-term solution can be found.
