Spring MVC - mvn package leads to "no main manifest attribute"

Hi,

I have a Spring MVC server generated using Swagger.. And normally, to start it we use mvn jetty:run.. But I'd like to create a JAR file that I can launch afterwards.. So, to do that, I use the command mvn package and it creates correctly the JAR file in the target folder.

But when I try to start it using the command java -jar swagger-spring-mvc-server-1.0.0.jar, I get this error: no main manifest attribute, in swagger-spring-mvc-server-1.0.0.jar.

If I'm right, this problem happens because the Main.class is missing.. But I didn't find any main classes in the generated code.

Does anyone knows if I'm doing something wrong?? Or if there's another way to get the JAR file? Thanks
