Thank you.

Answer 1

Check this answer: https://stackoverflow.com/a/4088861/5572007

You shouldn't use "-shaded" suffix. Quote: "[Shaded plugin] normally renames that jar to target/original-artifact-version.jar, and gives the shaded JAR the name target/artifact-version.jar". You can check your target folder for names of generated jar files.

Answer 2

Check that jar file corresponding to template really exists:

${project.build.directory}/${artifactId}-${version}-shaded.jar

You can replace this template to hardcoded full path to jar file and run build to verify all correct.
