org.codehaus.jackson versus com.fasterxml.jackson.core

Solution 1:

org.codehaus.jackson is an older version of Jackson.

com.fasterxml.jackson represents the new project and package.

The reason is, Jackson has moved from Codehaus to Github when releasing Jackson 2.

See here for details.

I would recommend removing org.codehaus.jackson references from your POM, re-building and looking for errors (not likely but possible).

If you find any, you can adapt the code using deprecated API to the newer Jackson version's API.
