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>
</execution>
</executions>
</plugin>

The plugin autodetects dependencies (fractions) for your project and includes all the requirements...
