The reason we should be intentional about dependencies, is to limit how often we need to change our code. Changes will ripple along those dependencies. Additionally, we need to handle the behavior of dependencies when unit testing.

Windows is a platform, Android is a platform, heck Firefox is a platform. All of these platforms provide a way to run 3rd party code, in the form of apps, programs or plug-ins. When exploring some options for pulling in and running 3rd party code within a rest-service, I realized I’ve never had to write a plug-in. Here’s a simple walk through of a simple plug-in example in Java.
