Running Queue jobs returns: ReflectionException: Method __PHP_Incomplete_Class::handle() does not exist

Hi, I've just come across the same issue in 5.4 on Forge and Envoyer. Did you find a solution?

I'm getting this error too, only in two particular jobs. Any solutions?

Yea, I'm getting this as well. Any solution yet?

Same

I also had this problem and found a fix. However, it turned out to be the result of multiple environments.

For example:

• I have a production and staging environment.
• The workers (Supervisor) on the server all use the same jobs table.

The problem is the workers--even after restarted to clear their cache--still only read the production environment's files so they truly cannot find the new Job class file.

The solution I cooked up was:

• Created a new migration for jobs_staging
• Updated /config/queue.php to add a new connection that looks at this new jobs table:

'staging' => [
    'driver' => 'database',
    'table' => 'jobs_staging',
    'queue' => 'default',
    'retry_after' => 90,
],

• Updated staging environment's .env file on the server and changed queue to use new connection: queue=staging
• Cleared the staging environment's config cache on the server: php artisan config:cache
• Updated Supervisor to include a new worker for staging:

[program:laravel-worker-staging]
process_name=%(program_name)s_%(process_num)02d
command=php /path/to/staging/current/artisan queue:work staging --daemon --sleep=3 --tries=3
autostart=true
autorestart=true
user=username_goes_here
numprocs=1
redirect_stderr=true
stdout_logfile=/path/to/log/supervisor/laravel-worker-staging.log

• Updated Supervisor: sudo supervisorctl reread
• Restated Supervisor: sudo supervisorctl restart

This fixed the problem for me.

It is a late post, but I too face the same issue and found the file name of the job file and the class name of the job is not matching.
