Description

Following this Spring MVC tutorial

https://www.djamware.com/post/5d9896d3abbb349ea4003e94/spring-boot-tutorial-build-an-mvc-java-web-app-using-netbeans

I created a Gradle Project using https://start.spring.io/

I downloaded the project as a zip and unzipped it into the Netbeans project folder, opened this as a project in Netbeans and built it.

The error occurred during the first run of the project.

Running a second time produced this error:
