One Spring Boot project, deploy to both JAR or WAR

Question

Is there a way to have a single Spring Boot project be packagable into both JAR and WAR without changing the pom.xml or the application source?

I\'ve re

Answer 1

I managed to do it by adding

${packaging.type}

to the POM file and then setting different profiles for JAR and WAR:

  
    
      jar
      
        jar
      
    
    
      war
      
        war
      
      
        
          org.springframework.boot
          spring-boot-starter-tomcat
          provided
        
      
    
  

Now mvn package -P war produces a WAR and mvn package -P jar produces a JAR.

Another option is to create separate modules for JAR and WAR, but I didn't go that route.
