title: Spring Boot Maven Plugin keeps duplicate jars -- is there a fix?
body: <p>We are seeing very large jar files created by Spring Boot Maven Plugin and upon examining them we found that there are many duplicate jars inside of it due to the structure of our multi-module project. We were able to reduce the size by excluding jars in the plugin config section, but this is a tedious and error-prone approach.</p>
  
  <p>We did not find any options to de-dupe the output jar, but maybe we missed something. Any advice is appreciated.</p>
