Ah.. the old days of java programming - set up your CLASSPATH and done.. Nowadays; however, most libraries have tons on other dependencies and doing this manually is tedious and a pain in the neck - download the wrong version of the dependency, and you are in for a rabbit-hole trying to figure out the compilation errors. Do not get me wrong, Maven is ugly and disgusting(so are the other dependency managers for java), but gone are the days of CLASSPATH.. unless you avoid using libraries bloated 3rd part libraries at any cost.
