Dependencies not shading with Maven shade

Question

I'm making a minecraft plugin for use with a server. I have tried to get jackson-databind to work so many times, however (with the use of jar tf) I find that jackson is never included and this then causes an error when my plugin loads. Either way, here's my pom.xml:

How can I make it so that jackson is actually in the compiled jar? (If it's of any use, I'm using Intellij IDEA to do all of this, including the maven stuff)

I have tried changing downloading the jar files for jackson-core and databind and using the system scope to get them into the pom.xml and changing the JDK version various times. I have also tried mvn clean and mvn package to see what happens.
