/**
 * <p>Retrieves the details of a maintenance window task.</p>
 *          <note>
 *             <p>For maintenance window tasks without a specified target, you can't supply values for
 *      <code>--max-errors</code> and <code>--max-concurrency</code>. Instead, the system inserts a
 *     placeholder value of <code>1</code>, which may be reported in the response to this command.
 *     These values don't affect the running of your task and can be ignored.</p>
 *          </note>
 *          <p>To retrieve a list of tasks in a maintenance window, instead use the <a>DescribeMaintenanceWindowTasks</a> command.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
