So you may be asking yourself at this point, what is this transitive concept? In short, a transitive dependency is a dependency of a dependency and so on. It provides a mechanism to not have to actually declare all of your actual dependencies, instead, focusing on what you know about. This reduces your need to know the inner workings of libraries while also isolating you from changes when upgrading versions. As you might imagine, since software is managing this transitive dependency process, there are rules, and these rules can get you if you don't know them. The first rule is that when two versions of an artifact are needed, the one closest to the actual project wins. Meaning if A has B and C, B relies on Z 1.0 and C relies on D, which also relies on Z 1.2, Maven will pick the version 1.0 because it's closer to A, two…
