gradle-in-action-source's Introduction

Source code for "Gradle in Action"

Building the code

All source code used in the book is based on Gradle 1.7. Please use the checked-in Wrapper to execute the samples. Please be aware that a later version of Gradle might not be compatible with the source code.

The source code is organized into individual chapters. Chapter 1 contains Ant and Maven build scripts. Please refer to the build tool's online manual for instructions to install the runtime and execute the build script. You can find more information here:

Starting with chapter 2, all source code can be run using the Gradle Wrapper which means no runtime will have to be installed. For example to run the "Hello World" build script from chapter 2 open a shell/command prompt and navigate to the directory. You can execute the build script by referencing the Gradle Wrapper command line script and providing the task you would like to run.

Windows:

> cd gradle-in-action-source/chapter02/helloworld-task-doLast
> ../../gradlew.bat helloWorld

*nix:

$ cd gradle-in-action-source/chapter02/helloworld-task-doLast 
$ ../../gradlew helloWorld

Putting it all together

Gradle in Action demonstrates how to implement build logic needed for various stages of a Continuous Delivery pipeline. While the book discusses specific functionality step by step, you might want to see it all put together. You can find the sample To Do application extended by typical project automation functionality (like testing strategies, publishing and deployment logic etc.) in a dedicated repository. Furthermore, you can find an updated version of the To Do application implemented with Spring Boot, built on a declarative Jenkins pipeline and deployed to Heroku in the blog post "Build pipelines with Jenkins 2 by example".

Going further

The book discusses how to integrate third-party functionality by writing custom tasks or plugins. Some of the examples have been developed further and are available as full-fledged binary plugins ready to be used in your own projects.

Gradle CloudBees plugin: A plugin that provides support for managing applications and databases on CloudBees RUN@cloud.
Gradle Vagrant plugin: A plugin for managing Vagrant boxes.

Unfortunately, I could not cover all topics readers were interested in. Here's a list of example projects that should get you started:

Gradle Android examples: Gradle became the default build tool for Android projects. This repository demonstrates the most common uses cases for the Gradle Android plugin.

Continuous Integration

Most of the source code listings are automatically executed with the help of the Gradle tooling API. Whenever there's a change to the code, a corresponding job is triggered. Each build works through a list of predefined tasks for each chapter and verifies the expected outcome.

gradle-in-action-source's Issues

In 2022, can't get examples to work in

First, thank you for writing this book!

Is it possible to run the code examples in a recent version of IntelliJ IDEA? I'm using 2021.3 Ultimate Edition. I'm using the gradle wrapper with the version set (see image below, note that the s is now required unlike a few years ago) as you suggest in your README, and I followed the tips you mentioned in this issue, but I get this output:

11:32 PM	Gradle sync failed: This version of Android Studio requires projects to use Gradle 4.8.1 or newer. This project is using Gradle 1.7.
			Change to minimum versions (plugin 3.2.0, Gradle 4.8.1) and sync project
			Change to latest versions (plugin 7.0.0, Gradle 7.0.2) and sync project
			Open build file (16 s 601 ms)

My settings look like this:

Now that it's 2022, should I just give up on getting the code to work, and instead follow the book content as best as possible, following up with something like the Udemy Gradle Masterclass?

Test report aggregation

The HTML files for both the unit and the integration test are generated into the tests folder but the index file is only linking into the unit tests

Would the book content still be useful for nowadays' software development?

Dear author, hope you are doing well.

I'm a beginner of gradle, I'd know more about Gradle to automate my software packaging and deployment. I'm just wondering that is the book still can apply to today's software development? thanks!

Can't get examples working

As I've been running through gradle in action examples using this code, they don't work. I've been using the gradle wrapper, but it complains about:

Is there any kind of way to migrate forward so I can make it through the examples in your book?
