Papyrus Designer is an extension of the Papyrus modeler. In order to install it, there are three different methods.
1. The easiest way (if Papyrus is not already installed) is to install the Papyrus SW designer RCP . Nightly RCPs for Eclipse 2023-03 are available as well .
2. Install Papyrus Software designer via the market place].
3. Open the standard Eclipse installation dialog (Help->Install New Software).
Within, add either a release update site of SW designer: Release 3.0.0, Release 2.1.0 (until 2021-06) or a nightly a nightly build , .
Please note that Papyrus SW designer depends on CDT (C++ code generation feature) and JDT (Java code generation) which both require a Java VM 17 in recent Eclipse version. This implies that you cannot use this installation option, if your existing Eclipse installation ships with an embedded Java VM that is older or the installed Java in your system is older. This is currently the case for Papyrus RCPs older than 2023-03.
