Building WAR file of maven project with vaadin

I'm trying to build a WAR file for my maven project which I used vaadin framework inside. When I run project in eclipse with jetty:run project runs smoothly. But when I tried to create a WAR file and deploy it to Apcahe Tomcat 10 I get the 404 Not Found error. When I searched online nearly every solution about the index.jsp file but I don't have an index.jsp file in my project. Packaging WAR is added in my pom.xml file. In mavens site the proper maven directory shows as follows enter image description here

But my directory is not same with the one here. I don't have web.xml and index.jsp file. It's probably because of the vaadin framework but I cant find a way to deploy project. Can anyone help me about this problem?

Thank you.

my pom.xml file looks like this.

Solution

  • Thanks to @PiotrP.Karwasz I downgrade the tomcat version to Tomcat9 from Tomcat10 and that solved the problem.
