Could not load codec 'Lucene62'. Did you forget to add lucene-backward-codecs.jar?

[Phil Ashworth]

Hi All

I've created a native java with lucene rdf4J 2.4.1 repository. 

It loads data through workbench fine and the lucene index seems to be created. index directory is created.

However clearing a context through workbench 

gives the error even though the operation seems to complete.

org.eclipse.rdf4j.repository.RepositoryException: org.eclipse.rdf4j.repository.RepositoryException: org.eclipse.rdf4j.sail.SailException: java.lang.IllegalArgumentException: Could not load codec 'Lucene62'. Did you forget to add lucene-backward-codecs.jar?

I also get the error now on loading data to the repository ( which didn't happen on first load) 

Once again the operation seems to complete as I see data. 

I have also looked back to 2.3.2 and I see the lucene-backward-codecs.jar seems to have been included in the rdf4J-server libs directory.

But it is not present in the 2.4.1 libs directory.

Can anyone tell me what is going on?

Cheers

Phil

Hi,

indeed, seems like the backwards-codecs jar aren't included anymore,.. 

Does downloading the codecs and putting the jar into the lib directory solve the problem ? 

http://central.maven.org/maven2/org/apache/lucene/lucene-backward-codecs/6.6.1/lucene-backward-codecs-6.6.1.jar

Best regards

I didn't try adding the codec. 

I could see the issue in the other post I put up. So I have had to bring all the repos up to the same level recreating everything which was a real pain.
