here answer.

stackoverflow huge me, have benefited anwsers of members, today happy participate community answer , hope developers me have no choice of working joomla.

so here how build cron joomla.

as elin says, there no cron builded in have use unix cron. cron call php script. make script work need load joomla framework.

you can exemple in /cli

here cron

<?php  // initialize joomla framework const _jexec = 1;  // load system defines if (file_exists(dirname(__dir__) . '/defines.php')) {     require_once dirname(__dir__) . '/defines.php'; }  if (!defined('_jdefines')) {     define('jpath_base', dirname(__dir__));     require_once jpath_base . '/includes/defines.php'; }  // framework. require_once jpath_libraries . '/import.legacy.php';  // bootstrap cms libraries. require_once jpath_libraries . '/cms.php';  // load configuration require_once jpath_configuration . '/configuration.php';  require_once jpath_base . '/includes/framework.php';  /**  * cron job   *  */ class mycron extends japplicationcli {     /**      * entry point script      *      * @return  void      *      * @since   2.5      */         public function doexecute()         {  // code here             require_once jpath_base.'/administrator/components/com_mycom/helpers/xmlimporter.php';              echo "cron task start ";         echo "\n"; // use \n executing cron terminal.              $instance = propertyxmlimporter::instance();             $instance->execute_import();          echo "cron task end ";         echo "\n";         }     }  japplicationcli::getinstance('mycron')->execute(); 

now need schedule cron.

open terminal , type

> crontab -e 

if opened vi text editor can press zz or :q! exit type better text editor (on mac)

> export editor=nano 

then

> crontab -e 

and add line :

*/1 * * * * php /applications/mamp/htdocs/yourproject/path-to-the-cron/crontask.php 

you can check ok typing

> crontab -l 

*/1 * * * * cron schedule syntax, check here read : https://en.wikipedia.org/wiki/cron

in our case used */1 trigger every minitues test purpose. of course want change when it's working. in case want run everyday @ 3am. changed 0 3 * * *

important 1 : launch cron job every minute test purpose don't forget /1 ! ( */1 * * * * ) not same (1 * * * *) . waiste bit of time on 1 ;)

important 2 : if error while excecution cron on localhost "could not connect mysql." change configuration.php with

public $host = '127.0.0.1';

instead of public $host = 'localhost'; yes 1 bi**h ! lost few hours on ...

important 3 : code wrote above, if put cron in /cli. i'm not sure best place, remember adapt path cron location.

i hope !
