java - Why spring boot generates jar or war file with .original extension?

Question

Why after building spring boot app, it generates two jar or war files with .original extension? I use spring boot maven build plugin. For example:

1. application.war
2. application.war.original

Answer 1

The answer is that you are using repackage goal in your spring-boot-maven-plugin. So, What it does?

Maven first builds your project and packages your classes and resources into a WAR (${artifactId}.war) file.

Then, repackaging happens. In this goal, all the dependencies mentioned in the pom.xml are packaged inside a new WAR (${artifactId}.war) and the previously generated war is renamed to ${artifactId}.war.original.
