Book on Amazon.
So, as I promised earlier I publish my review.
First of all I would say that subject book is very easy for ubderstanding.
You will not find here advanced topics such as repository or distribution management but this book can be very helpfull if you migrating your project from Ant to Maven.
That is really cookbook - it contains a lot of relatively simple recipes.
I think this book will be very usefull for maven beginners.
