I've now found this earlier thread: http://mail-archives.apache.org/mod_mbox/lucene-solr-user/201701.mbox/%3ccakhkodqv-y59+7m86ogvf1feqj6ieiogp8trhl1mg5fuajl...@mail.gmail.com%3e in which the second message (from Shawn Heisey) says: > I actually do not know what the path for lib directives is relative to > when running SolrCloud.

So is this the definitive answer? As I suggested in my earlier message, the documentation in the user guide at https://lucene.apache.org/solr/guide/8_1/resource-and-plugin-loading.html strongly suggests that you _can_ use plugin JARs uploaded to a collection's znode.
