Build war file from Vertx project using Maven - maven

Question

I've created a Vert.x project referring this. Also created a run configuration in eclipse referring this. The project successfully run as an application project in Eclipse and http://localhost:8080 is accesible.
As per the document it uses maven shade plugin to build a fat-jar (if I build it using Maven via terminal), which I only copy pasted, not understood much.
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.3</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<manifestEntries>
<Main-Class>io.vertx.core.Launcher</Main-Class>
<Main-Verticle>${main.verticle}</Main-Verticle>
</manifestEntries>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/services/io.vertx.core.spi.VerticleFactory</resource>
</transformer>
</transformers>
<artifactSet>
</artifactSet>
<outputFile>${project.build.directory}/${project.artifactId}-${project.version}-fat.jar</outputFile>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.5.0</version>
<configuration>
<mainClass>io.vertx.core.Launcher</mainClass>
<arguments>
<argument>run</argument>
<argument>${main.verticle}</argument>
</arguments>
</configuration>
</plugin>
</plugins>
Every examples says to create the jar file and run it on terminal. But I need to deploy this project into a tomcat server, as a WAR file. This server system is not accessible for me, so I must hand over the WAR to admin.
How can a WAR file be produced from this ? Please help!

Answer 1

A Vert.x application, although may be embedded into existing applications, is meant to be executed on its own (which may help you avoid many issues including ClassLoader ones).
Following the mentioned guideline, you should have created a Web API using Vert.x and which runs under the hood by an embedded server which prevents you from using Tomcat as a runtime container.
