Flow 14 with Jetty embedded

Is there some example Maven project with Vaadin Flow 14 and Jetty embedded?
I found this one: [https://github.com/mvysny/vaadin14-embedded-jetty]
(https://github.com/mvysny/vaadin14-embedded-jetty) ,
but it creates a little strange Jar file. After start it with 'java -jar ’ it download and unpack many files/folders and
creates some files in start directory. How can i hide all this inside Jar?

Actually we need to create FAT JAR applications, that can be started on servers without internet connection and without
installed application servers. Spring Boot is also unwanted.

Hello Alexander, I’ve added the answer to the following github bug report, please let’s continue the discussion there: https://github.com/mvysny/vaadin14-embedded-jetty/issues/1

Is there no possible way to achieve simple JAR for starting with ‘java -jar’?
