Gradle Effective Implementations Guide - Second Edition

Defining tasks

A project has one or more tasks to execute some actions, so a task is made up of actions. These actions are executed when the task is executed. Gradle supports several ways to add actions to our tasks. In this section, we discuss about the different ways to add actions to a task.

We can use the doFirst and doLast methods to add actions to our task, and we can use the left-shift operator (<<) as a synonym for the doLast method. With the doLast method or the left-shift operator (<<), we add actions at the end of the list of actions for the task. With the doFirst method, we can add actions to the beginning of the list of actions. The following script shows how we can use the several methods:

task first { doFirst { println 'Running first' ...
