Solr's source in subversion has moved within the ASF repository to to https://svn.apache.org/repos/asf/lucene/solr/ (Thanks Doug!)
The easiest way to change your working directories is to use "svn switch". For example, if you have the "trunk" of solr checked out, cd to that directory and execute svn switch https://svn.apache.org/repos/asf/lucene/solr/trunk Don't forget to change any SVN paths that may be configured in your IDEs too. -Yonik
