Apache Tika : Settting classpath for opennlp models on tika-server - apache-tika

Question

I can't seem to set the classpath for the tika-server so that the opennlp models are detected correctly.
I've followed the instructions here:
https://wiki.apache.org/tika/TikaAndNER
(substituting app for -server, seen as that looked like it contained everything required)
I have created the following folder structure
tika
`-- tika-ner-resources
`-- org
`-- apache
`-- tika
`-- parser
`-- ner
`-- opennlp
|-- ner-location.bin
|-- ner-organization.bin
`-- ner-person.bin
Running:
java -classpath tika/tika-ner-resources -jar tika-server-1.18.jar --config /etc/tika-config.xml -enableUnsecureFeatures -h 0.0.0.0
and issuing
{{ curl -v -XPUT --data-binary #test.pdf http://localhost:9998/tika --header "Accept: text/plain" --header "Content-Type: application/pdf"}}
results in
INFO going to load, instantiate and bind the instance of org.apache.tika.parser.ner.opennlp.OpenNLPNERecogniser

The only thing that seems to work is re-packing the jar by adding the contents of the tika/tika-ner-resources directory (i.e. org/blah/blah/*.bin). The curl command then executes without any issues. I've also tried almost every combination of setting the classpath.
Does anyone have any ideas ?

For anyone else having issues, the following command worked for me by removing the -jar and manually specifying the TikaServerCli class
java -classpath tika/tika-ner-resources/:tika-server-1.18.jar
org.apache.tika.server.TikaServerCli --config /etc/tika-config.xml -enableUnsecureFeatures -h 0.0.0.0
