Notes: You should execute the goal at the install phase, not the package phase. The origin jar file in install phase does not contain necessary dependencies in the file content. while the jar file in the install phase contains the necessary dependencies in it which is repackaged by spring boot plugin.

install

maven command
run mvn package install instead of mvn package, to copy the final jar to expected output directory.
