java.lang.NoClassDefFoundError: org/apache/commons/codec/digest/MurmurHash3 in Indexing Triplestore

[davidemerlitti]

I get this error (MurmurHash3 class not found) while performing triplestore indexing by invoking the command:

curl -XPOST localhost:9080/reindexing -H"Content-Type: application/json" -d '["broker:queue:triplestore.reindex"]'

Is the dependency on the org.apache.commons.codec.digest package missing?

The error only comes up for the following resource which contains blank nodes:

Is there any way to fix this?

Attached the fcrepo-camel-toolbox out.log file.

Inside the jar I'm using to execute fcrepo-camel-toolbox (fcrepo-camel-toolbox-app-6.1.0-SNAPSHOT-driver.jar) there is 'org/infinispan/commons/hash/MurmurHash3.class' and not 'org/apache/commons/codec/digest/MurmurHash3'.

Good question, I'll try to replicate the issue and see if we can resolve it for you.

@whikloj Thank you. My quick and dirty fix was to manually add the missing class into the jar. That was enough to make it work.
