Summary of Changes

Hello @feeblefakie, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request backports changes to enable the Gradle build cache for improved build performance. It also includes an upgrade of the Gradle wrapper to version 8.14.3 and updates to the Gradle wrapper scripts to align with modern execution practices and licensing.

Highlights

• Enabled Gradle Build Cache: The Gradle build cache has been enabled by adding org.gradle.caching=true to gradle.properties, which will significantly improve build performance by reusing outputs from previous builds.
• Upgraded Gradle Wrapper Version: The Gradle wrapper has been upgraded from version 8.7 to 8.14.3, ensuring the project uses a more recent and potentially more stable or performant version of Gradle.
• Updated Gradle Wrapper Scripts: Both the gradlew (Unix) and gradlew.bat (Windows) wrapper scripts have been updated to include the SPDX license identifier and to modify how the Gradle wrapper JAR is executed, transitioning to a direct -jar execution method.

Code Review

This pull request backports changes to enable the Gradle build cache and upgrade the Gradle version. The changes to the Gradle wrapper scripts and properties are mostly correct and align with the goal. However, there is a critical issue with the specified Gradle version in gradle-wrapper.properties, which appears to be invalid and will likely break the build. I've left a specific comment with a suggestion to fix it.

[gemini-code-assist]

The Gradle version 8.14.3 specified in distributionUrl appears to be invalid as it does not correspond to an official Gradle release. This will cause the build to fail with an error when trying to download the Gradle distribution.

The original commit that is being backported uses version 8.8. Please update the URL to use a valid Gradle version.

distributionUrl=https\://services.gradle.org/distributions/gradle-8.8-bin.zip
