Gradle Goodness Notebook

Experience Gradle through code snippets

About the Book

In 2009 I started to write small blog posts about Gradle at Messages from mrhaki. The posts contained code samples of cool Gradle features I just didn't want to forget. The blog posts turned out to be a useful resource for people learning and using Groovy in their every day programming.

The Gradle Goodness Notebook contains the blog posts about Gradle previously mentioned on my blog. The posts have been edited slightly so they can be used for the book. The book gives a broad overview of all the great features we can find in the Gradle build tool.

Latest update on April 18, 2023 with the following blog posts:

  • Defining Plugin Versions Using Version Catalog
  • Grouping Version Catalog Dependencies Into Bundles
  • Set Test Framework Version Using Version Catalog With JVM Test Suite Plugin
  • Using Spock With JVM Test Suite Plugin
  • Add Extra Dependencies For Running Tests Using JVM Test Suite Plugin
  • Set Project Version In Version Catalog
  • Configure Test Task With JVM Test Suite
  • Publish Version Catalog For Sharing Between Projects

The book contains the following sections:

  • Configuration
  • Tasks
  • Command line
  • Java and Groovy
  • Managing Dependencies
  • Testing Support
  • IDE
  • Miscellaneous

About the Author

Hubert Klein Ikkink
Hubert A. Klein Ikkink (mrhaki)

Hello. I am a passionate Groovy and Java developer based in Tilburg, The Netherlands. My goal is to write software, like Pixar makes movies, BMW makes cars, Bang & Olufsen makes audio and TV systems and Apple makes computers and devices: clean, elegant, user-centered and high quality.

My name is Hubert A. Klein Ikkink. Not a very common name, right? To make things easier I just picked the first letters of my firstname and surname and came up with haki. So there you have it, now I am known as Mr. Haki or mrhaki for short.

In 2009 I started writing blog posts about Gradle with the name Gradle Goodness. These posts contain small snippets of code explaining core and exotic features of the Gradle build tool.
