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:
application.war
application.war.original
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
