Packaging plugin + viewpoint

Hello,
I’ve made a plugin for Capella 1.1.0 using Capella Studio 1.1.0.
But the problem is that I don’t know how to build an installation package…
I’ve tried to select all my projects in my workspace and export them all as
deployable plug-ins and fragments, then I copy the files into capella/eclipse/plugins.
But then, only the viewpoint appears into Capella…
Best regards,
Matthieu Durot
