I merged the existing spring-boot-maven-plugin settings with the one provided in your docs.

The huge question is: Must the application be app and running on port 8080 prior to running the command above?

I made it work by removing:

                    <execution>
                        <id>pre-integration-test</id>
                        <goals>
                            <goal>start</goal>
                        </goals>
                    </execution>
                    <execution>
                        <id>post-integration-test</id>
                        <goals>
                            <goal>stop</goal>
                        </goals>
                    </execution>

and running the app on 8080, priror to running maven mvn -Pprod,war clean verify -DskipTests=true command.
