We've just released an alpha build of Maven: The Definitive Guide, it is the first update in a number of months and we're gearing up for a lot of activity over the next few weeks. This newer version of the book is a complete rework of the last release with a focus on being concise and comprehensive. We'll be releasing two more chapters a week over the next month, so stay tuned.
I jumped into this book at the end of last year, and took the original content and decided to split the book up into two parts. Part I is a "by example" approach to Maven with an entirely new set of examples. Part II is more reference material. We're still evolving the final structure of the book, but we've decided that we're going to be as transparent as possible as we finish this book. Consider the book we released today to be an early alpha, you are definitely going to find some grammar and spelling problems, and we're working furiously to produce a product that doesn't sacrifice content or quality.
If you've been reading the book, you'll notice that there are a few missing chapters. We've removed some of the material that dealt with plugin usage, site generation, and others. We have about seven chapters on in development right now. Stay tuned to this blog for more updates. We're committed to opening up the writing process and being as transparent as possible.
