Hi, can you post final solution how you solve this problem?

I have copied solr-analysis-extras-7.3.0.jar to /contrib/analysis-extras/lib
folder and loaded it like this:

/<lib dir="${solr.install.dir:../../../..}/contrib/analysis-extras/lib"
regex=".*\.jar" /> /

but error have not gone...

I still see:
org.apache.solr.common.SolrException:org.apache.solr.common.SolrException:
Error loading class 'solr.OpenNLPExtractNamedEntitiesUpdateProcessorFactory'
