It was a great honor to be asked by Packt Publishing to write this book. I knew beforehand it would be a lot of work and somehow needed to be combined with my daytime job. I couldn’t have written the book without the help of a lot of people and I would like to thank them.

First of all I would like to thank my family for supporting me while writing this book. They gave me space and time to write the book. Thank you for your patience and a big kiss for Kim, Britt, and Liam; I love you. I also like to thank my colleagues at JDriven. They reviewed the pages I wrote and helped me by asking questions and showing interest in the progress of the book. Of course I like to thank all the people at Gradleware for making Gradle such a great build tool and René Gröschke for reviewing the chapters in the book.

Finally I’d like to thank the great staff at Packt Publishing. Sai Gamare kept me on schedule and made sure everything was submitted on time. I’d also like to thank all the editors for reviewing the book. They really helped me to keep focus and be concise with the text.
