Subject Re: Error when using IndexMergeTool
Date Fri, 25 Aug 2017 21:16:41 GMT
You classpath is not correct. Unless it's a typo,
:"C:solr/server/solr-webapp/webapp/WEB-INF/lib/lucene-misc-6.5.1.jar"
is wrong, it should be:
"C:/solr/server/solr-webapp/webapp/WEB-INF/lib/lucene-misc-6.5.1.jar",
note the slash before "solr".

If that's not just a typo you need to look further as to why the
classpath isn't being specified correctly.

Best,
Erick
