How to use the electron-builder-util/out/log.warn function in electron-builder-util

function createDownloadOpts(opts: any, platform: string, arch: string, electronVersion: string) {
  if (opts.download != null) {
    warn(`"build.download is deprecated — please use build.electronDownload instead`)
  }

  const downloadOpts = Object.assign({
    cache: opts.cache,
    strictSSL: opts["strict-ssl"]
  }, opts.electronDownload || opts.download)

  subOptionWarning(downloadOpts, "download", "platform", platform)
  subOptionWarning(downloadOpts, "download", "arch", arch)
  subOptionWarning(downloadOpts, "download", "version", electronVersion)
  return downloadOpts
}

function subOptionWarning (properties: any, optionName: any, parameter: any, value: any) {
  if (properties.hasOwnProperty(parameter)) {
    warn(`${optionName}.${parameter} will be inferred from the main options`)
  }
  properties[parameter] = value
}
