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

    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.

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 When then opening those “outdated” index files it will throw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.

Additionally there is nothing wrong with your ServiceLoader and you don’t
need to unzip the webapp. In lucene-core.jar file the meta-inf classes are
always available and the exception you posted clearly shows that it *has* 3.
x and 4.0 and SimpleText codec. The IAE is simply caused by the outdated
index format which forces it to lookup a codec with the empty string as name
(which of course does not exist).
