Unable to run OptaPlanner to optimize a school timetable example in Eclipse

Unable to run OptaPlanner to optimize a school timetable example in Eclipse - java

I trying to setup the TimeTable example from OptaPlanner (link here) from copying the needed dependency for Maven and all the relevant code. However, when I try to run it, error occur.
Side note, I trying to copy over the TimeTable to our existing Java Spring Boot version 2.4.5 project.
Below is the error:
Below is my project pom.xml:

Take a look at this suggestion from the stacktrace you pasted, I suspect that will fix it:

The right place of class path is
This is from different classes and from different project.
The question How to make library comes from maven instead of coming from java library. After clone new project from github.

#Jahongir ResponseEntity class is a part of spring web dependency So, you don't need to add httpClient to get this class.

WildFly doesn't read application.properties on SpringBoot project

I have a project with the structure below, It works when I use eclipse->Run As-> Spring Boot App, but if I run it on WildFly my application.properties is not readed. I know that, because when I execute in SpringBoot the url is http://localhost:8000/gigy/ and when I execute on WildFly the url is http://localhost:8080/springBootRestApi-0.0.1-SNAPSHOT/, I need to execute it on a server because I need to debug the program. I readed some similar posts but they did not work for me.
my application.properties
server.port=8000
server.contextPath=/gigy
logging.level.com.gigy=DEBUG

or

Thank you for your help.

So I figured out the package I need is servlet and not server. I don't know if the package was renamed tough.
Anyway thanks for the help!
