Subject RE: Codec with name ‘Lucene40′ does not exist

Hi Lili,



The problem is another one: Lucene trunk has no stable index format as it is
not yet released. We changed the index format several times causing older
indexes not to be readable anymore (of course 3.x indexes are always
readable). When then opening those “outdated” index files it will throw
this or similar exceptions.



You have to completely delete your index and reindex. This is the backside
of using a trunk version.



Uwe

Subject: Codec with name ‘Lucene40′ does not exist



hi all

    when I run/debug solr in eclipse, an error occured.

   Caused by: java.lang.IllegalArgumentException: A SPI class of type
org.apache.lu

cene.index.codecs.Codec with name '' does not exist. You need to add the
corresp

onding JAR file supporting this SPI to your classpath.The current classpath
supp

orts the following names: [Lucene40, Lucene3x, SimpleText]

    I found this webpage http://blog.so8848.com/2011/11/55863.html

    It seems there is something wrong with ServiceLoader.

    So I use ant to build the whole project and unzip
/META-INF/services/org.apache.lucene.index.codecs.Codec into my source code
folder

    But it still failed.

    In eclipse's catalina base:
