i'm not very familiar with that wiki, but note the line in the example ant script...
<!-- SOLR_HOME must be set as an environment variable --> ... : --solr.xml <-- Where i can find this file? according to the wiki page... > First we will setup a basic directory structure (assuming we only want to > change some fields) and copy the attached build.xml and solr.xml: ...i addume it is refering to what you named build.xml ... if you name it solr.xml i think you would need to run "ant -f solr.xml mysolr.dist" ... but like i said, i'm not too familiar with that wiki, so i could be wrong. -Hoss
