The maven shade plugin is creating a file called dependency-reduced-pom.xml and also artifactname-shaded.jar and placing them in the base directory.
See https://issues.apache.org/jira/browse/MSHADE-121, and also https://issues.apache.org/jira/browse/MSHADE-124.
There is an option to move the d-r-p to elsewhere, but you may not like the consequences.
You are wrong about the -shaded jar, it always ends up in target/ unless you move it elsewhere.
