Just a wild guess here, but...
Try doing one of two things:
1. change the package name to be something other than o.a.s....
2. Change your config to use solr.FacetCubeComponent
You might also try turning on trace level logging for the
SolrResourceLoader and report back the output.

I am trying to get a custom plugin to work properly. When I put

missing besides just dropping it into the directory?
Works:
{solr.home}/tomcat/webapp/solr/WEB-INF/lib/
Doesn’t Work:
{solr.home}/lib/
