Lucene upgrade cause exception on startup #4

Closed olatignies closed 7 years ago

olatignies commented 7 years ago

java.lang.IllegalArgumentException: Could not load codec 'Lucene40'. Did you forget to add lucene-backward-codecs.jar?

Prevent from upgrading to new 20170131 version.

java.lang.IllegalArgumentException: An SPI class of type org.apache.lucene.codecs.Codec with name 'Lucene40' does not exist. You need to add the corresponding JAR file supporting this SPI to your classpath. The current classpath supports the following names: [Lucene54]

Found the solution, when you upgrade the Snomed release, you should clean the index folder before loading the new version. As the previous index was indexed with Lucene version 40, it just try to update the index, but this specific version is not available in the most recent version (migrated to version 5).

Hi @olatignies, yes that's a good catch! Thank you. I'll update the README.
