Changelog

v2.8.0

Compare Source

The v2.8.0 release of the gradle-build-action introduces an easy mechanism to connect to Gradle Enterprise, as well improved support for self-hosted GitHub Actions runners.

Automatic injection of Gradle Enterprise connectivity

It is now possible to connect a Gradle build to Gradle Enterprise without changing any of the Gradle project sources. This is achieved through Gradle Enterprise injection, where an init-script will apply the Gradle Enterprise plugin and associated configuration.

This feature can be useful to easily trial Gradle Enterprise on a project, or to centralize Gradle Enterprise configuration for all GitHub Actions workflows in an organization.

See Gradle Enterprise injection in the README for more info.

Restore Gradle User Home when directory already exists

Previously, the Gradle User Home would not be restored if the directory already exists. This wasn't normally an issue with GitHub-hosted runners, but limited the usefulness of the action for persistent, self-hosted runners.

This behaviour has been improved in this release:

• The Job Summary now includes a useful error message when Gradle User Home was not restored because the directory already exists.
• The action can now be configured to restore the Gradle User Home when the directory already exists, overwriting existing content with content from the GitHub Actions cache. See https://github.com/gradle/gradle-build-action#overwriting-an-existing-gradle-user-home for more details.
