Eclipse Papyrus 5.0.0

Papyrus 5.0 contains new features:

• it is now possible to associate a set of customization of the model explorer to the architecture framework.

A huge job has been done to remove all re-exports on dependencies.

Now papyrus 5.0 compiles on Java11.

Note that all the relative: Sysml 1.4, 1.6, Moka, designer... have also been reworked to be compatible with work on re-exports and on Java11.
