Problem building WAR in IntelliJ

Hello,

I am somehow not able to build a working WAR after reinstalling my pc.

When I launch tomcat I get the error 'Failed to load the bootstrap javascript: ./VAADIN/vaadinBootstrap.js?v=7.5.1'

This is how the WAR is set-up

But there is something faulty.

Here is a tree from the exploded WAR

Somehow I got 2 VAADIN outputs

And here is a tree from an older WAR (working)

Thanks in advance for your help.

Looks like you have completely empty /WEB-INF/lib folder inside your WAR. That could be the reason.
