I've developed a Java Application by mean a Maven Project with NetBeans 8.1.
This application run as it's expected on NetBeans environment, using "Run project".
But now, I want to run the application outside NetBeans ,(in production).
By mean "Clean and Build", I get the jar in the maven local repository. But when I try to run this jar, I get:
"no main manifest attribute, in DerquiSystemsManagerFrontEnd-1.0-SNAPSHOT.jar"

How can I get a runnable jar from a Maven Project in NetBeans?
(I do not know much about Maven.)

Thank you, in advance.
