Introducing Java Toolchains

Gradle 6.7 introduced Java toolchain support which was further enhanced in Gradle 6.8. This feature provides an easy way to declare with what Java version the project should be built. It detects installed JDKs and downloads one if needed. Learn more in the blog post.

Upgrading Gradle Survey

We published a survey asking about the user experience when upgrading Gradle so we can improve it. Your opinion is important to us and we would appreciate it if you could spend a few minutes answering those questions.

Gradle 6.8

Gradle 6.8 has been released. This release includes a much faster Kotlin DSL compilation and other performance optimizations, improvements to Java toolchain support including vendor selection, convenient execution of tasks in composite builds, new APIs for consistent dependency resolution, and other improvements. See release notes for details.

Gradle Enterprise 2020.5

Gradle Enterprise 2020.5 has been released. It features Distributed Testing for Maven builds which executes your existing test suites faster by distributing them across as many machines as you provide. See the release notes for details.
