This chapter is deprecated. While the original version of Maven: The Definitive Guide had an entire chapter dedicated to the Nexus Repository Manager, Sonatype found that the content was growing fast enough to deserve its own dedicate title. We've decided to spin off the content in the Repository Management chapter into a new book called Repository Management with Nexus. This new book covers both Nexus Open Source and Nexus Professional, it guides you through the process of downloading and installing a repository manager, and it provides a detailed survey of all of the configuration options.

Note
In the past, a book was a very static object, it was written, edited, proofread, and printed. After printing there was little time to reconsider the structure or content of a book. While the Internet has offered an opportunity for the real-time, constantly evolving on-demand book, the publishing industry has yet to come to terms with the idea of a book that is "alive" - a book that can change the day after it was sent to the print, and a book that can split into two and continue to grow. We decided to make this break because it makes sense, if one of our chapters starts to grow into a hundred-page beast, we're not just going to throw more pages at an already "thick" reference book. (But then again, this book isn't "thick" if you are reading it in a web browser, it is all about perspective.)
What's true about software development is also true about writing. If you start out a project with a single, monolithic project, there is going to come a time when it makes good sense to refactor a package or collection of classes into a separate module. That is exactly what we are doing by spinning the Repository Management chapter into Repository Management with Nexus. We're "refactoring" the book into two.
Consider this editor's note to be a deprecation warning. Eventually, we're going to remove this marker chapter from the book entirely. On the web it will be a HTTP redirect to the new book, and in the PDF it might be a place-holder page that references the Nexus book.
