in the past (somewhere around 8.4) it was possible to include plugins into a "hidden" plugin application for referencing them in other apps.
As André stated, this is still possible to include the plugins in a "hidden" application, but the plugins from the hidden application are not visible to another application during development in the local cumulocity tools runtime.
In an older version of "cumulocity-tools" (Version 2.0.26) the local development server detected all other applications, that exist in the same parent folder during the startup of the development server (c8y server
command)
Is there a configuration parameter to enable this detection?
