Subject Re: An error I can't manage to fix: java.lang.NoClassDefFoundError: org/apache/solr/search/QParserPlugin

This is pretty fragile, the Jetty work directories come and go.

I predict it will keep disappearing and/or you'll go through this same hassle
next time you re-install or move to a new machine or...

You *should* be able to just remove that directory entirely and still start w/o
copying the jar.

Are you absolutely sure you have a <lib> directive in your solrconfig.xml
file that paths to a directory that has your spatial jar in it?
