Hey, so I'm trying to get the jackson library for JSON parsing included on my IntelliJ IDEA Spigot Plugin project, in order to store some persistent player data. However, I get this error: Error: (8,28) java: package org.codehaus.jackson does not exist What I did was: 1. Download jackson library, extract and put .jar file in a lib folder within the project for convenience. 2. right click .jar within intellij idea & click Add as library... I even get object completions pointing to the library as you can see in the following images :/ All seems fine but I get the error. What else do I need to do besides the steps I already followed in order to fully import this library?
