Configuring Maven is deceptively simple, after all, it's just a matter of writing XML, isn't it? Things look differently when the rubber meets the road. One must know the intricacies of the build lifecycle; how plugins, goals (mojos), and phases come together; rules for dependency resolution; configuration inheritance between parent-child POM files; enhancing the build with profiles; and more.
