How to build jar file in Intelij Idea IDE?

Question

Java

Tell me how to build a jar file in this programming environment?
The result is not a jar file, but an application configuration file, only .ini Maybe someone is familiar with such a problem.
In general, I go into architecture, choose to build a jar file, choose main class, but there is no jar.

Well I do like in my question How to run jar from Intelij IDEA in Ubuntu 14.04? however, the jar itself does not start for me. If it starts up for you, please let me know.
