Innovative microservice packaging with WildFly Swarm

WildFly Swarm is a WildFly extension project that aims to facilitate Java EE applications with minimum dependencies in the form of an executable JAR, called Uberjar or flat-jar. This JAR is deployed on an embedded container derived from the WildFly application server. WildFly Swarm is an initiative around the microprofile that aims to optimize Enterprise Java for a microservices architecture.
To create a flat-jar from a web application, you simply have to use the WildFly Swarm Maven plugin to package your web application:

<plugin>
    <groupId>org.wildfly.swarm</groupId>
    <artifactId>wildfly-swarm-plugin</artifactId>
    <version>${version.wildfly.swarm}</version>
    <executions>
     <execution>
      <goals>
       <goal>package</goal>
      </goals&gt...
