Crucible add-on failed to enable

[A P]

Hi. I tried to test my Crucible add-on via 'atlas-run' and it failed to be enabled with message

This add-on failed to enable. Refer to the logs for more information

But there are no error messages in atlas-run console. Then I tried to install plugin package to production Crucible server, but I also failed to enable plugin with no error log messages. Here you can read atlas-run log. Can anyone help with finding out the cause of error?

Take a look FECru server logs in directory: target/fecru/home/var/log/ 

It should be a information from plugin system stating why plugin can't be enabled.
