How to resolve JAR conflicts with maven-shade-plugin

I have two projects: jartest and jarprj. jartest depends on poi 3.17, whereas jarprj depends on poi 5.10. jartest encounters an error when dynamically loading jarprj. The error message is as follows:

java.lang.reflect.InvocationTargetException
    at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
    at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)

The issue may stem from a conflict between the versions of poi. I attempted to rename poi using the maven-shade-plugin, but the error persists. The error message is as follows:

jartest cannot upgrade its poi version, while jarprj requires poi 5.1.0. What methods are there to solve this? How can we resolve it using maven-shade-plugin?
