Gradle 6.6 releases: automation building tools

2 min read

Gradle is a build tool with a focus on build automation and support for multi-language development. If you are building, testing, publishing, and deploying software on any platform, it offers a flexible model that can support the entire development lifecycle from compiling and packaging code to publishing web sites. It has been designed to support build automation across multiple languages and platforms including Java, Scala, Android, C/C++, and Groovy, and is closely integrated with development tools and continuous integration servers including Eclipse, IntelliJ, and Jenkins.


  • Highly customizable — Gradle is modeled in a way that customizable and extensible in the most fundamental ways.
  • Fast — Gradle completes tasks quickly by reusing outputs from previous executions, processing only inputs that changed, and executing tasks in parallel.
  • Powerful — Gradle is the official build tool for Android, and comes with support for many popular languages and technologies.

Changelog v6.6

Performance improvements

Fast feedback for local incremental builds is crucial for developer productivity. This is especially true when your IDE uses Gradle to build and run tests for your project, which IntelliJ IDEA does by default. This scenario has been the primary focus of performance improvements since Gradle 6.5 and will continue for the next several Gradle releases.

Configuration caching

Before running any task, Gradle needs to run the configuration phase. Currently, this is done on every build invocation and can incur a noticeable overhead, especially in large projects.

The configuration cache significantly improves build performance by caching the result of the configuration phase and reusing it for subsequent builds. Using the configuration cache, Gradle can skip the configuration phase entirely when nothing that affects the build configuration has changed as you can see below.
