El primer paso es crear un proyecto Maven, usamos Maven para no tener problemas de dependencias y generar el jar de una forma r\u00e1pida y comoda. Podemos usar el arquetipo quickstart, que es el m\u00e1s simple de todos, una vez hemos creado el proyecto, desde la consola o desde nuestro ide preferido, vamos a editar el POM para obtener todas las librer\u00edas precisas, si alguna de las que ponemos en este ejemplo no la puede encontrar vuestro maven, usad maven central para buscar una versi\u00f3n m\u00e1s actual o a\u00f1adid el jar a vuestro repositorio local.
