Review Comment:
   Better relativize `outputFile` to `project.projectDir` (or better 
`this.workingDir`) here (and in other places) so the `commandLine` doesn't 
contain any local paths.
   
   **Within** a task configuration block, you can 
   ```suggestion
       val outputFile = 
helmTestReportsDir.get().file("minikube-images.sha256").relativeTo(project.projectDir)
   ```

Review Comment:
   The cached outputs are (hopefully) relatively small-ish, compared to the 
execution time of these tasks.

Review Comment:
   All `Exec` tasks also need
   ```suggestion
       outputs.cacheIf { true }
   ```
   otherwise only up-to-date checks work, but nothing would be cached. (`Exec` 
is annotated with `@DisableCachingByDefault`.)
