Vaadin example app running in Embedded Jetty

vaadin-boot-example-maven's Issues

Experiment with jar-with-dependencies

Along the zip file, also create a jar-with-dependencies as described at https://www.baeldung.com/executable-jar-with-maven .

Akin to Spring Boot, the jar would contain other jars as dependencies packaged inside. That solves the limitations of uberjar (unpack all dependencies then zip it into one huge jar) which disallows duplicate resources (such as META-INF/MANIFEST.MF and service loader config files).

Fails to start from uberjar

When I try to run it using the uberjar it fails with this:

IllegalStateException: UI.getCurrent() is null. Have you called MockVaadin.setup()?

Hey, some test is failing for me, any ideas why?
I am using a modifed version of this example which you can find here: https://github.com/Osiris-Team/vaadin-boot-example-1jpm
However I compared the pom.xml files and they should be pretty similar still.
Can you reproduce this issue on the original vaadin-boot-example-maven repo?
