Hi GD, No idea why maven can't work, or the project structure is a little complex？
Also sure that lucene 2.9 has no problem with this because it does not depend on SPI. First you need to check the fat jar file and the file META-INF/services/o.a.l.codecs.Codec and its counterparts are there. If no, then the workaround is to have way to add all META-INF/services/xxx into your fat jar. If yes, the problem may be with classloader, classloader can't locate the SPI file within its context, I guess it's not this case. Hope this help. Best regards, Duke If not now, when? If not me, who?
