For the generation the groupId also defines the package of the main class. artifactIddefines the unique name of the artifact. In our case it's the same like the groupId, but it could also be a simple name like "SuperCalculator". The generation uses this value as name of the root folder for out project. packagingdefines the packaging method. This could be e.g. jar, war or ear.
