Thank you Duke for your help. We have already tried that solution
after a kindly advise from this mailing list. But we still having
the error. Actually the POM of the project is here http://lesimisped.free.fr/servo/pom2.xml. It reuses a project which uses Lucene, and the POM is this project is http://lesimisped.free.fr/servo/pom.xml. With a similar project which uses lucene 2.9 we didn't experienced such an issue. Hope that may help. Best regards, GD Le 20/08/2013 16:10, Duke DAI a écrit :

Maven Shade is used for assembling the project (P1) which depends on another project which uses Lucene (P2). P2 uses lucene.core, lucene.queryparser, lucene.analyzercommon. Please find enclosed a screen-shot of the services of the two Jar. We use to use previous versions of lucene (2.x) and we perform the same process of assembling without issue. Hope this could help. best regards, Amal 2013/8/16 Uwe Schindler <u...@thetaphi.de> Hi, Maven makes it even simplier to handle this! The problem may be (I amnotsure not sure, because I don’t know your setup): It seems that you are using the Maven Shade Plugin to merge all JARfilesinto one BIG JAR file. During this step, you may be missing to merge all the data correctly in your JAR files. Lucene JARs also contain metadataandother resources (in addition to class files) in the META-INF folders and those are generally not always merged by all those tools, so those mustbecopied and merged if multiple META-INF/services with same name exist.TheMaven-Shade-Plugin can do this for you, see:http://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.htmlEspecially:http://maven.apache.org/plugins/maven-shade-plugin/examples/resource-transformers.html#ServicesResourceTransformerIt is recommended to use the ServicesResourceTransformer option. Ideally, you should not change or transform JAR files of Lucene at all and not merge them, just ship them with your project as is. Please keep them separate, only for special use cases like autostarting double-click JAR files, merge them otherwise management gets crazy. In any case, please check your classpath: - Are the *unmodified* lucene-core.jar files in it? - Don't use crazy classloader hierarchies. Keep all Lucene code together in one classloader (so don't place Lucene JAR files outside your webapp, but the code using lucene inside a webapp). - If you create uber-JARS (which is a bad idea in general), use Maven-Shade plugin and configure it correctly. The Uber-JAR file must contain a "META-INF/services" folder with some org.apache.lucene.index.* files. ----- Uwe Schindler H.-H.-Meier-Allee 63, D-28213 Bremen http://www.thetaphi.de eMail: u...@thetaphi.de-----Original Message----- From: Amal Kammoun [mailto:kammoun.ama...@gmail.com] Sent: Friday, August 16, 2013 5:39 PM To: java-user@lucene.apache.org Subject: SPI class of type org.apache.lucene.codecs.Codec error Hi, We are working on a project which uses Lucene 4.2.1. Actually we arefacingan error message "java.lang. ExceptionInInitializerError". We are using Maven for assembling theprojectand we have a dependency between two projects. When we do the test with eclipse it works fine. However, when we incorporate our jar in aclientthat is tested outside Eclipse we got thejava.lang.ExceptionInInitializerError.We are doing workaround to overcome the issue since yesterday, we gotthesame issue with both versions of Lucene 4.2.0 and 4.2.1. Have you ever experienced such an issue with maven? Are the newer Lucene versions safer from such an issue? Here is the rest of the message error Caused by: java.lang. IllegalArgumentException: A SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene42' does not exist.Youneed to add the corresponding JAR file supporting this SPI to your classpath.The current classpath supports the following names. Thank you a lot in advance for your support.
