cannot install UML Designer from Marketplace, nor as plugins

[jadelkhoury]

Although I can download UML Designer as a ready application (from http://www.umldesigner.org/download/), I cannot seem to be able to install UML Designer in any form onto an existing Eclipse installation.
(Why don't I just use the stand-alone application? I am trying to integrate UML Designer with another Sirius-based plugin.)

I have tried different versions of Eclipse, and Update sites, with no success. Hard to share all options, but here is the most concrete setup on Eclipse 2019-09 R (4.13.0). I have Sirius
6.2.3.201908120659 installed.

1. When I try to install as plugin, I get the following error, when I try to install the Plugin version 9.0.0.201901300933

Cannot complete the install because one or more required items could not be found.
  Software being installed: UML Designer 9.0.0.201901300933 (org.obeonetwork.dsl.uml2.runtime.feature.feature.group 9.0.0.201901300933)
  Missing requirement: UML Designer 9.0.0.201901300933 (org.obeonetwork.dsl.uml2.runtime.feature.feature.group 9.0.0.201901300933) requires 'org.eclipse.equinox.p2.iu; org.obeonetwork.dsl.uml2.core.runtime.feature.feature.group 0.0.0' but it could not be found

2. I tried to install via the marketplace, and then UML Designer cannot be found with the default Eclipse Marketplace. But if I choose the Obeo Marketplace, I can find it. BUT it cannot be installed. See picture below

Did you try to install thanks to the update site : https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/9.0.0/repository/
It should work with a Sirius 6.1 and Eclipse Oxygen.

[jadelkhoury]

My aim is to actually make it work on Eclipse Oxygen, but there I need to use Sirius 5.1.1 (due to the other product).
With Oxygen Build id: 20180405-1200, I tried each of the repos in attached picture. They all give the same error.

It seems that org.obeonetwork.dsl.uml2.runtime.feature and/or org.obeonetwork.dsl.uml2.core.runtime.feature is missing?

[mbats]

So for Sirius 5.1, the good repo is the 8.1 version : https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/8.1.0/repository/

Could you share the error you get with this repo please?

The error is:

Cannot complete the install because one or more required items could not be found.
  Software being installed: UML Designer with Product Specific Branding 8.1.0.201807261234 (org.obeonetwork.dsl.uml2.runtime.product.feature.feature.group 8.1.0.201807261234)

Here are the 2 steps to get to that error:

Step2, after waiting some time, and then I press the "stop" button:

Can you try by selecting only UML Designer and UML Designer SDK

[jadelkhoury]

Same problem. I also tried with just UML Designer, and that did not help either.
Maybe it is that particular version of Oxygen that is a problem? What version are you using?

[enwi]

For me the solutions depicted in this issue did not work either. What did work though was to deinstall Sirius first and install UML Designer from here specifically this link https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/9.0.0/repository/ which was also mentrioned above.

The same error still persists on eclipse 2022-12:

Cannot complete the install because one or more required items could not be found.

I' using this update site:
https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/9.0.0/repository/

There is no way to install the UML Designer with or without Sirius. Tried to install it from:
http://download.eclipse.org/sirius/updates/releases/7.0.6/2021-06

Can some please confirm any working configuration based on a current eclipse release? Thanks!

I also had this problem. You should add the https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/9.0.0/core/repository/ to your available update sites (note the /core/ in the url), before installing UML designer from https://s3-eu-west-1.amazonaws.com/obeo-umldesigner-releases/9.0.0/repository/. The missing org.obeonetwork.dsl.uml2.core.runtime.feature.feature.group is located there.
