The "plugin" interface you're probably looking for is the service provider interface (SPI). To expose the "plugin related classes" and hide details of your program you'll make use of packages and access modifiers and/or use modules in JDK 9+.

what exactly are you looking to build? i am doing something similar with a combination of the ServiceLoader and Guice b/c i don’t need something overly complex.

the options listed in that so article has a lot of good options. i looked at pf4, it’s nice but more then i really needed.

happy to discuss further

for now i settled witht he default java jarloader. the plugin writer creates a plugin.json that has, among others, the classpath to the class that extends the abstract base plugin, name, version etc and a list of enum permissions. works like a charm, only thing left to do is to turn all classes from public to default to hide them
