Cache cleanup fails with "Unable to locate executable file: gradle" when Gradle is not pre-installed on runner

[ashirman]

Our gradle action config looks as the following

    - name: Setup Gradle
      uses: gradle/[email protected]
      with:
        gradle-version: wrapper
        gradle-home-cache-cleanup: true
        cache-read-only: false

so assumption is that in post-action gradle will clean up cache in home directory thanks to gradle-home-cache-cleanup: true. Actually in Post Setup Gradle I see the following message

Post job cleanup.
In final post-action step, saving state and writing summary

based on sources https://github.com/gradle/gradle-build-action/blob/main/src/cache-cleaner.ts I see as if dummy gradle project does actual clean up. But from where this project should get gradle to execute this

        await exec.exec(`gradle -g ${this.gradleUserHome} --no-daemon --build-cache --no-scan --quiet noop`, [], {
            cwd: cleanupProjectDir
        })

?

Would you please clarify how to properly configure gradle-home-cache-cleanup so it would get gradle from somewhere. Thanks!
