self-contained executable jar file that we could run in production. Executable jars (sometimes called “uber jars” or “fat jars”) are archives containing your compiled classes along with all of the jar dependencies to distribute a self- contained application. To solve this problem, many developers use “uber” jars. An uber jar packages all the classes from all the application’s dependencies into a single archive configure the spring-boot-maven-plugin to prevent the repackage goal from adding the dependency into the uber jar: org.springframework
