This indicates your deployment is missing a JAR in the classpath at run time that was available at compile time. You’ll probably want to double check how you deployed your vert.x app.

3

The jackson-core 2.10.0 is in the bundled jar

4

The problem is why the cocuhbase is using com.fasterxml and not the dependency which is bundled in core-io ?

Hi Himanshu,

The problem is why the couchbase is using com.fasterxml and not the dependency which is bundled in core-io ?

Couchbase SDK 2.x doesn’t use com.fasterxml. That stack trace is coming from Vert.x, not the Couchbase SDK.

The missing class com.fasterxml.jackson.databind.deser.std.JdkDeserializers lives in the jackson-databind jar. Try adding that to your bundled jar as well as jackson-core.

Thanks,
David
