Maven shade output not found - maven

Question

I'm using the Maven Shade plugin, but I can't find its output.
The log says it clearly : the Maven-shade-plugin has worked.
But in the end, the output of the plugin is not where it is supposed to be.
Why ?
Maven log:
--- maven-shade-plugin:2.0:shade (default) # zploger ---
Including log4j:log4j:jar:1.2.17 in the shaded jar.
Including zparkingb:utils:jar:1.5.0 in the shaded jar.
Including zparkingb:swing:jar:1.5.6 in the shaded jar.

Attaching shaded artifact.
And the pom/xml.
