Description

Most every attempt to use post.jar fails, but the simplest is:

java -jar post.jar -help

This gives the response:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/solr/util/CLIO
    at org.apache.solr.util.SimplePostTool.info(SimplePostTool.java:735)
    at org.apache.solr.util.SimplePostTool.main(SimplePostTool.java:167)
Caused by: java.lang.ClassNotFoundException: org.apache.solr.util.CLIO

This is true even though:

jar -tvf solr-core-9.0.0-SNAPSHOT.jar | grep CLIO
