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 When then opening those “outdated” index files it will throw this or similar exceptions.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.

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:
