Sourced from gradle/actions's releases.

v4.0.0-rc.1

First release candidate for v4 of the setup-gradle, dependency-submission and wrapper-validation actions provided under gradle/actions. This is the first release available under the v4 tag.

Major changes from the v3 release

The arguments parameter has been removed

Using the action to execute Gradle via the arguments parameter was deprecated in v3 and this parameter has been removed. See here for more details.

Cache cleanup enabled by default

After a number of fixes and improvements, this release enables cache-cleanup by default for all Jobs using the setup-gradle and dependency-submission actions.

Improvements and bugfixes related cache cleanup:

• By default, cache cleanup is not run if any Gradle build fails (#71)
• Cache cleanup is not run after configuration-cache reuse (#19)

This feature should help to minimize the size of entries written to the GitHub Actions cache, speeding up builds and reducing cache usage.

Wrapper validation enabled by default

In v3, the setup-gradle action was enhanced to support Gradle wrapper validation, removing the need to use a separate workflow file with the gradle/actions/wrapper-validation action.

With this release, wrapper validation has been significantly improved, and is now enabled by default (#12):

• The allow-snapshot-wrappers makes it possible to validate snapshot wrapper jars using setup-gradle.
• Checksums for nightly and snapshot Gradle versions are now validated (#281).
• Valid wrapper checksums are cached in Gradle User Home, reducing the need to retrieve checksum values remotely (#172).
• Reduce network calls in wrapper-validation for new Gradle versions: By only fetching wrapper checksums for Gradle versions that were not known when this action was released, this release reduces the likelihood that a network failure could cause failure in wrapper validation (#171)
• Improved error message when wrapper-validation finds no wrapper jars (#284)

Wrapper validation is important for supply-chain integrity. Enabling this feature by default will increase the coverage of wrapper validation on projects using GitHub Actions.

New input parameters for Dependency Graph generation

Some dependency-graph inputs that could previously only be configured via environment variables now have dedicated action inputs:

• dependency-graph-report-dir: sets the location where dependency-graph reports will be generated
• dependency-graph-exclude-projects and dependency-graph-include-projects: select which Gradle projects will contribute to the generated dependency graph.
• dependency-graph-exclude-configurations and dependency-graph-include-configurations: select which Gradle configurations will contribute to the generated dependency graph.

Other improvements

• In Job summary, the action now provides an explanation when cache is set to read-only or disabled (#255)
• When setup-gradle requests a specific Gradle version, the action will no longer download and install that version if it is already available on the PATH of the runner (#270)
• To attempt to speed up builds, the setup-gradle and dependency-submission actions now attempt to use the D: drive for Gradle User Home if it is available (#290)
