Hello all,

I had tried to install the Papyrus-RT Developer Environment by following the Papyrus-RT/Developer/Developer Guide/DevEnv Guide (Setting up the Developer Environment) for release Oxygen.

While processing the P2 Director I got error (see below). I am not sure what the issue is. Has anyone encountered such an error before? Any assistance you provide will be of help.

Thank you

That's a problem in the Papyrus setup file and you should really report it to the Papyrus team, so that they know that their setup information is needed by contributors and that this information should be correct and up to date.

As Oxygen is already released I wouldn't expect UML milestone drops under 5.3. Until the Papyrus team has fixed the problem in their project setup you can work around it by (literally) copying the following snippet:

<?xml version="1.0" encoding="UTF-8"?>

... and then pasting it into your user setup, i.e., select the menu Navigate | Open Setup | User, select the "User" node in the editor and select the menu Edit | Paste.
