If you’re familiar with Gradle’s basics elements—possibly through the author’s previous O’Reilly book, Building and Testing with Gradle—this more advanced guide provides the recipes, techniques, and syntax to help you master this build automation tool. With clear, concise explanations and lots of ready-to-use code examples, you’ll explore four discrete areas of Gradle functionality: file operations, custom Gradle plugins, build lifecycle hooks, and dependency management.
Learn how to use Gradle’s rich set of APIs and Groovy-based Domain Specific Language to customize build software that actually conforms to your product. By using the techniques in this book, you’ll be able to write domain-specific builds that support every other line of code your team creates.
Examine Gradle’s file API, including copy tasks, pattern matching, content filtering, and the FileCollection interface
Understand the process for building and packaging a custom Gradle plug-in
Manage build complexity with hook methods and Gradle’s rule feature
Learn how Gradle handles dependency management natively and through customization
Explore Gradle’s core plug-ins as well as key examples from the Gradle community

It's a great work not for absolute beginner. You should have some Gradle's background before, and preferably, have a bit of experience in build's scripting. The book clearly explains a lot of useful, real life use cases. There is a bunch of good examples attached and available at github.
Bottom Line Yes, I would recommend this to a friend
It is a quite short book (only 4 chapters) that presents you some more advanced topics of Gradle. Tim Berglund cover here topics such as: file copying & processing tasks, building custom plugins, using hooks to life-cycle events and management of dependencies.
I enjoyed the book. It is easy to read as the authors show many snippets of code as an example for the topics he covers. And because of the relatively short length of the book, you don't need to spend a lot of time reading about details that you probably don't care about.
The book is definitely not for those who are new to Gradle build system. I believe that you should at least be familiar with topics covered in previously published "Building and Testing with Gradle". The authors assumed that the reader already know how to use Gradle and quickly started with describing another features of it.
On the other hand, if you already know how to use it then you might not need to read this book at all. If in your job you need to use more advanced gradle tools, you might as well use only official online documentation, which most probably already covers all the topics from the book. The only benefit you will have from reading Tim's book is that he covered some example step-by-step instructions for using these advanced features, like creating custom plugins.
Bottom Line No, I would not recommend this to a friend
