Description

When i try to run the shade goal of the maven-shade-plugin:3.2.4, an exception gets thrown when it gets to the Minimizing jar... phase. The exception says:

 Error creating shaded jar: Unsupported class file major version 61 -> [Help 1]

I assume this means this build step doesn't support java 17? If so, I also assume this is a bug. Please tell me if that is not the case, or if I did something wrong.

Kind regards, mufinlive
