Right, component isn't a thing. I probably shouldn't use that term. I want to standarize on the naming convention of plugin, module, and extension. It is explained a bit on the wiki [1] but I'll try to do a little better job here. So a plugin is basically a jar. A jar contains multiple modules. A modules ends up being a spring application context that composes multiple configuration files. Modules are assembled into a hierarchy at runtime. Extensions are implementations of interfaces that exist in a module. A maven project produces a jar, so a plugin ends up being a maven project also.
So currently today we don't have a strong definition of Plugin and I hope to address that.
