    logger.info <<~EOL
      This has been deprecated and :CACHE_ROOT should not be in the config.build.cache_dir setting.
      The :CACHE_ROOT pattern has been removed from config.build.cache_dir automatically.

      To remove this warning, remove the :CACHE_ROOT. For example:

      config/app.rb

          config.build.cache_dir = "#{old_pattern}"

      Update it to:

          config.build.cache_dir = "#{pattern}"

    EOL

  path = "#{Terraspace.cache_root}/#{path}"
  path.gsub!(%r{/+},'/') # remove double slashes are more. IE: // -> / Useful since region is '' in generic expander
