Dynamically set API version in code from pom.xml. Great on CI where one is not manually tempering with versions.

<!-- Then in Code `getClass().getPackage().getImplementationVersion()`   -->
<!--  For Example to set API on Swagger do:

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .version(getClass().getPackage().getImplementationVersion())
                .build();
    }
