I am a very infrequent user of Eclipse and new to the topic of UML modelling.
Eclipse: Version: Mars.2 Release (4.5.2)
Build id: 20160218-0600
When it comes to installing Papyrus, my guess is that I should stick to the MARS version of Papyrus. This is what my installation dialogue looks like:
After pressing next, the screen shows me a warning "Cannot perform operation. Computing alternate solutions..." and when I press "Show original error and build my own solution" my screen looks like this:
How do I adress this problem and is this kind of behavior expected? I would have hoped for the Eclipse installer to solve these dependencies.
I'm not sure whether you depend on the Eclipse Mars version for other projects. If not, I would propose to take the Oxigen version.
You can find it here: https://www.eclipse.org/papyrus/download.html
Scroll down to the RCP version and you will have a all-in-one installer of Papyrus' latest version.
In case you depend on Mars for other reasons, you can still complete the process as you were doing. You were only a bit too eager to select all components. Most people only need to take the "Papyrus" package, not the other ones such as "Qompass".
Johan, thanks for your guidance! I managed to successfully install the Oxygen Version of Eclipse and then added Papyrus Oxygen using using the "Install Software feature" from the Help Menu. This time it worked!
