00:19:28,370] WARN Variables cannot be used in the 'plugin.path' property,
since the property is used by plugin scanning before the config providers that
replace the variables are initialized. The raw value 'null' was used for plugin
scanning, as opposed to the transformed value 'null', and this may cause
unexpected results.
