Cron in my custom module is not running

Question

I have created a cron group as below,

cron_groups.xml

<?xml version="1.0"?>
<!--
/**
 * path:
 * magento_home/app/code/vendor/module/etc/cron_groups.xml
 */
-->
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Cron:etc/cron_groups.xsd">
    <group id="sync_api">
        <schedule_generate_every>1</schedule_generate_every>
        <schedule_ahead_for>4</schedule_ahead_for>
        <schedule_lifetime>2</schedule_lifetime>
        <history_cleanup_every>10</history_cleanup_every>
        <history_success_lifetime>60</history_success_lifetime>
        <history_failure_lifetime>600</history_failure_lifetime>
        <use_separate_process>1</use_separate_process>
    </group>
</config>

And my crontab.xml as below

<?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="sync_api">

    <job name="custom_cronjob" instance="Ucs\Api\Sync\Test" method="execute">

        <schedule>*/5 * * * *</schedule>

    </job>

</group>

</config>

After adding this, I executed, upgrade, compile, cache:clean commands, Once it is done,

I've run a command as php bin:magento cron:run

Once all done, I checked cron_schedule and have found my next cron is not at all scheduled.

Also, in the admin stores->configuration->advance->cron tab I can see my sync_api tab. I have configured Generate Schedules Every as 1.

After all these tries, nothing works.

** Edit **

Obviously, I did cron run by group,

Even after doing that I haven't found the scheduler in cron_schedule table.

Answer 1

You have to run your cron group via below code:

php bin/magento cron:run --group="sync_api"

Also before do this,please clear the cache.

Please follow the below articles for setup custom crontab group at magento 2
