Failure when installing Eclipse Modeling tools (updated) [message #1764864] Fri, 02 June 2017 16:34 Go to next message

I'm trying to use Oomph (1.7.0 build 3044) to install Eclipse Modeling Tools (Neon, linux, 64bit), but I get an error. The feature org.eclipse.m2m.atl.emftvm.feature.group cannot be found. The same error happens when I try to install Eclipse IDE for Java Developers or Eclipse IDE for Eclipse Committers.
I found that the missing feature is available at http://download.eclipse.org/mmt/atl/updates/releases but that repository is not one of the repos listed in the log.

UPDATE:
This works fine on another machine, but there it doesn't try to install the ATL EMFTVM. Earlier I experimented with creating an Oomph setup in an existing eclipse installation (without success). Somehow the installed features of my current installation seem to get merged with what will be installed when choosing a configuration in the installer. Is there a way to prevent that?

UPDATE 2:
I was able to resolve the issue by deleting everything oomph related from $HOME/.eclipse. However, I'm still not sure what went wrong and how to prevent similar issues in the future.

I don't see a requirement for such an IU in the product catalog. The Neon Modeling product version requires these:

  <repository

</setup.p2:P2Task>

So I would not expect any addition root requirement other than these and the ones required by the types of Oomph tasks that are needed.

I tried just now to install the Neon Modeling product version and that worked. Are you doing something else you're not telling me about? Perhaps you could attach the setup.log so I have more clues...

I've updated my original post. Experimenting with Oomph authoring seem to have caused the issue. The installation in which I did this has ATL installed and somehow that was merged into the product catalog. I have not the slightest idea what I did to make that happen, though.
After deleting all directories with Oomph in their name from the .eclipse directory installation works as expected.

Perhaps you put a p2 task in your user.setup? Certainly things can be added to the user extensible product catalog but you'd have to explicitly choose such a product. Only things in your user.setup would be automatically "merged" with whatever product you're installing. E.g., I have a p2 task in my user.setup to install vi into every installation I create...

In the end, the products in the generated product catalog are not themselves ever modified by any normal actions that you do. I.e., they're not editable by you locally and when they're changed by us in our git clone, that new version will be downloaded but every client...
