Subject Recompilation of latest lucene seems to break update of Solr
Date Wed, 26 Jul 2006 13:19:34 GMT
Hello,

   jhust compiled the latest version of lucene (), updated the  
webapps/solr/WEB-INF/lib/ with the 3 jar files:
     lucene-core-2.0.1-dev.jar
     lucene-snowball-2.0.1-dev.jar
     lucene-highlighter-2.0.1-dev.jar
   Restarted solr, The Admin interface of solr is still running, but  
trying to send updates to solr gives me the following error:

   I read in the mailinglists of lucene that they changed the  
Fieldable into Field:

LUCENE-545 that was recently committed breaks backward compatibility  
with
Document.getField(),  a non-expert level API that is *very* widely used.

Something simple like
   Field x = mydoc.getField("x");
no longer compiles (and neither do other methods with Field in the  
signature).

Is this intentional?
If not, uses of "Field" in unit tests should not have been changed to  
Fieldable.


   Anybody an idea how to solve my problem. I jhust want to change  
some stuff in the lucene itself and replace the jar files on solr  
with the newly created (compiled) ones

   Thanks

   tom
