"Apache Maven 3 Cookbook" is an introductory Maven book. It explains the concepts well. It's been a while since I read a Packt book and it looks like they fixed the proofreading/formatting problem. I only noticed one formatting error, which is nothing. And it was 5.o vs 5.0 - hardly something that interferes with readability.
The beginning was a bit repetitive. The how to install for Windows/Mac/etc repeat pieces instead of having one section and showing the differences.
The cookbook recipes show common things you'll start with - building different types, a Spring app, etc. It even shows Google app engine. The book also includes tools like coding standards. The author says codings standards tools help "lesser experienced programmers adhere to standards expected of them." Hmm. Experienced folks need standards too. Can't remember everything!
That would be only complaint. The book shows so many different things, there isn't room for depth. I have concerns about the depth of the Sonatype book too though so I can hardly hold it against the Packt book. (I'd like links to references on where plugin variables and the like are stored.)
Disclosure: I received a copy of this book from the publisher in exchange for writing this review on behalf of CodeRanch.
