remove the <packaging>pom</packaging> from your pom.xml and then run mvn clean install
it should work
you have used packaging type pom , you should use the jar, The default packaging type is jar, If you don't have any it will use packaging as jar
The packaging type of a Maven project specifies the type of artifact the project produces. There are many built-in Maven packaging types (for example, jar, war, and ear).
A pom type is packaging a kind container of submodules, a submodule is represented by a subdirectory in the same directory
