System cron starts Magento 2 cron every minute:
$ crontab -l */1 * * * * /usr/bin/php /home/user/prj/mage2/bin/magento cron:run >> /home/user/prj/mage2/var/log/cron.log I see new line Ran jobs by schedule. is added every minute into the log.
This is my settings for my task:
<?xml version="1.0"?> <config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/crontab.xsd"> <group id="default"> <job name="my_own" instance="\Vendor\Module\Cron\Task" method="execute"> <schedule>...</schedule> </job> </group> </config> These settings run my job every 15 minutes in fact (my own message is added every 15 minutes into the log):
<schedule>* * * * *</schedule> <schedule>*/1 * * * *</schedule> This is my log:
... Ran jobs by schedule. Ran jobs by schedule. Ran jobs by schedule. My own job is started. Ran jobs by schedule. ... These are Magento 2 cron settings: 
How can I set <schedule> to run my task every 1 minute?
