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
2
javaspring-bootjarwar
How are you building your war? Are you using Maven? Can you share your pom.xml? Are you using spring-boot-maven-plugin? – user2241537

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.

I assume that you're using the spring boot maven build plugin. This behavior is documented here: https://docs.spring.io/spring-boot/docs/current/reference/html/build-tool-plugins-maven-plugin.html
