Really guys?! I'm gonna have a hard time giving a positive review if the install doesn't even work...

On a completely fresh Eclipse Oxygen instance I got the following error:

Cannot complete the install because one or more required items could not be found.
  Software being installed: UML Designer SDK (
  Missing requirement: UML Designer ( requires ' 0.0.0' but it could not be found
  Cannot satisfy dependency:

I have installed it in Eclipse Neon, worked with the first go.
A bit of a change of mindset if you come from a IBM Rational Software Architect perspective. I love the separation of model information (.uml) from the view information (.aird), it solves a huge complain from many of my colleagues in the financial services industry, especially if you are into model driven development; why parse a huge file (model + view) when you are just interested in the model only.
Also love the fact it is Eclipse EMF based, loads of previous eclipse plugins can still be ported with slight modification.
Keep up the good work!

The UX is appalling, the usability product bears no relation to the "Getting Started" tutorial on the plugins website and doesn't appear to function correctly via exploration. Add lots of meaningless/opaque options but most result in empty and non-functioning popups. Uninstall doesn't function correctly, with numerous options left handing around in Eclipse.

So many errors, I must been submitted at least 20 different bugs in less than 20 minutes.
I couldn't find the Java generator code.
I have a "decent pc" with SSD, and every action takes between 3-7 seconds to response

it looks like a situation which could be caused by a configuration or an environment issue.

Would you mind sharing your feedback, OS, UML Designer and Java versions through an issue so that we can help in troubleshooting this ?

Horrible resolution on my 23 inch iMac, horrible UI totally unfriendly and that was only on the most basic class diagram!

I can create a combined fragment with loop as Interraction operator, but how to insert it on the sequence diagram ?

When trying to do the "Create an UML project" tutorial, I see the following error message:
"Error loading cheat sheet content.
Cheat sheet content file '/doc/cheatsheets/CreateProject.xml' could not be parsed, error at line '47', column '9'."
And the tutorial is not launched.

I looked for this file and I found it in the following path:
The file has effectively an error at line 47, in a followed by a text that has closing quotation mark but not has not opening quotiation mark and lacks the "label" attribute definition, making it an invalid XML file.
However, after adding the "label" attribute and quotation mark for the text and saving the file, eclipse still shows the same error message when trying to launch the tutorial, even if the file is now valid XML.
