How to make Spring Boot include the manifest file in its repackaged WAR?

I'm building a Spring Boot application using spring-boot-starter-parent version 2.1.0-RELEASE and need it to produce a deployable WAR file containing a MANIFEST.MF in the META-INF/ directory. I've set up the Maven WAR plugin to include the manifest in the build artifact:


However, the final build artifact doesn't include a manifest file. I noticed that Spring Boot performs a repackaging after the Maven WAR plugin packaged the WAR file in the first place:

[INFO] --- spring-boot-maven-plugin:2.1.0.RELEASE:repackage (repackage)

And indeed the artifact.war.original in the target directory does contain the manifest.

How do I make Spring Boot to include the manifest in the final WAR file as well?

#java #maven #spring
