jena-serviceenhancer NoClassDefFoundError

Version

5.0.0-rc1

What happened?

I am trying to add the server enhancer plugin to fuseki server as described here:
https://jena.apache.org/documentation/query/service_enhancer.html

I downloaded the .jar file from here:
https://mvnrepository.com/artifact/org.apache.jena/jena-serviceenhancer/5.0.0-rc1

And placed it in /home/ubuntu/apache/apache-jena-fuseki-5.0.0-rc1/run/extra.

Getting the error attached below:

Downloading the Gauava .jre from here:
https://mvnrepository.com/artifact/com.google.guava/guava/33.0.0-jre

And placing it in run/extra resolved the issue.
