Hello!
I've tried to install a plugin genrated with Xtext 2.9.1 in Eclipse Photon (Version: Photon Milestone 6 (4.8.0M6) Build id: 20180315-1217) getting the following error:
An error occurred while collecting items to be installed
session context was:(profile=epp.package.jee, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).
No repository found containing: osgi.bundle,prometheuss,1.1.13.201710061140
No repository found containing: org.eclipse.update.feature,prometheuss.sdk,1.1.13.201710061140
No repository found containing: osgi.bundle,prometheuss.ui,1.1.13.201710061140
My questions:
1. Is there a workaround to install the plugin (the problem doesn't exist in Eclipse Oxygen)?
2. If I have to migrate to the current Xtext version, is there some documentation how to do it?
Thanks for your answers.
Best regards, Andreas.

Hi Andreas!

The only fishy thing I see here is org.eclipse.update.feature. Where did you get that from? Might be related to the drop of the Update Manager API in Photon M4:

Not really. If you are already on the new project structure with the .ide project you are relatively safe. We always take care of keeping backward compatibility as far as possible.
The usual way to do this is to create a new project with similar configuration and compare the relevant parts, e.g. dependencies, Manifest, pom.xml etc.
Don't forget to merge plugin.xml_gen.
The rest is custom implementation. This can't be predicted by documentation.

Hello Karsten,
thanks for your hints. I've created a new project and got it to build the plugin based on the new project structure and Xtext 2.14.0. So far, so good.
The problem comes with installing it, still missing some dependencies:
Cannot complete the install because one or more required items could not be found.
Software being installed: PrometheussDSL Feature 1.0.0.201805180724 (prometheuss.feature.feature.group 1.0.0.201805180724)
Missing requirement: prometheuss 1.0.0.201805180724 (prometheuss 1.0.0.201805180724) requires 'osgi.bundle; org.eclipse.xtext.xbase.lib 2.14.0' but it could not be found
Cannot satisfy dependency:
From: PrometheussDSL Feature 1.0.0.201805180724 (prometheuss.feature.feature.group 1.0.0.201805180724)
To: org.eclipse.equinox.p2.iu; prometheuss [1.0.0.201805180724,1.0.0.201805180724]
I don't know if this is an Xtext or Eclipse Photon problem?
Best regards
Andreas
