Hi there,
The carrot2 download links are broken. I have file a bug with them: > > http://issues.carrot2.org/browse/CARROT-653 > It's fixed now, thanks for the report! When Solr switches to Carrot2 v3.2.0 (https://issues.apache.org/jira/browse/SOLR-1804), which is LGPL-free, the extra build dependency on the remote resource will be gone too. Cheers, Staszek
