Honor custom distributionPath for caching downloaded wrapper distributions

[cloudshiftchris]

The distributionPath property in gradle/wrapper/gradle-wrapper.properties is not used when caching distributions. It appears that caching is only supported for the default wrapper/dists location.

Thanks for the report: you're assessment is correct. Currently the gradle-build-action can only save/restore wrapper downloads that are located in the default location. Are you setting only distributionPath or are you also specifying distributionBase in gradle-wrapper.properties?

You can configure the action to save/restore more directories inside the Gradle User Home directory, but there's no way to tell the action to save/restore directories outside of the Gradle User Home.

As a workaround:

• If your wrapper dists are located in a different location in Gradle User Home, you could configure gradle-home-cache-includes with the extra location.
• If your wrapper dists are located outside of Gradle User Home, then you could setup caching of this directory with actions/cache

Thanks for the info.

Use case is separating our custom Gradle distributions from standard distributions to aid in install / maintenance.

e.g.
distributionPath=wrapper/my-dists

...within the GRADLE_USER_HOME distributionBase.

Is there specific cache logic for wrapper/dists that wouldn't be applied using a generic gradle-home-cache-includes?

Yes, the Gradle wrapper distributions are saved and restored independently of the rest of the Gradle User Home, with the aim to increase sharing between different projects/builds using the same Gradle version.

Another option you have to workaround this limitation is to fork the action and add your custom distribution base here: https://github.com/gradle/gradle-build-action/blob/main/src/cache-extract-entries.ts#LL341C32-L341C32. Note that you'll need to run npm run build to regenerate the transpiled sources.
