[Nubebuster]

When I add this project to my project and I try to compile, I get "Unsupported class file major version 60".

Am I doing something wrong?

By removing the relocation from my pom it now works. How do I correctly relocate without breaking it?

The version of maven-shade-plugin is lower than 3.3.0 and the filter section is missing.
