Sounds very familiar. I was a Java developer for a long time, and in that ecosystem adding a library to your project can be enough for code to be activated and run. There are plenty of libraries where the idea is: just include it, magic stuff will happen, and everything works! That is, until it doesn't work. And then you have to try and debug all this magic stuff of how Java automatically loads classes, how these classes are created and run, and what they do. Didn't happen very often, but when it happened usually a full week was wasted with this.

I really prefer spending a bit more time to set it up myself (and learn something about what I'm using in the process) and knowing how it works, than all the implicit magic.
