Releases #

Gradle Build Tool 7.6 #

This release includes building and running code with Java 19, a flag to rerun tasks individually, a new strongly-typed dependencies block for JVM test suites and a pluggable system for Java Toolchains provisioning. See release notes for details or watch the release video highlights.

Gradle Enterprise 2022.4 #

Gradle Enterprise 2022.4 makes class-level faults and bottlenecks in JVM-based tests for Gradle and Apache Maven™ easier to identify and diagnose, increases the predictive accuracy of Predictive Test Selection without sacrificing time savings, and enables programmatic administration of Test Distribution agents. See release notes for details.

Test Retry Gradle Plugin 1.5.0 #

Some of your tests are flaky? The Test Retry Gradle Plugin 1.5.0 plugin causes failed tests to be retried within the same task. After executing all tests, any failed tests are retried. The process repeats with tests that continue to fail until the maximum specified number of retries has been attempted or there are no more failing tests.

This new release now also allows declaring test classes that must be retried as a whole unit, for example, if test methods depend on each other. This can be configured via qualified class name patterns or annotations on the class level.

Gradle Enterprise Gradle Plugin 3.12 #

This release adds built-in support for https://github.com/gradle/develocity-testing-annotations, captures skipReasonMessage when specified for the task, and includes test retry functionality provided by the Test-Retry Gradle Plugin (above). See release history for details.

Other Releases #

IntelliJ IDEA 2022.3 #

IntelliJ IDEA 2022.3 introduces improvements for working with build.gradle files in Groovy projects and much faster code completion in build.gradle.kts
