I get this error when running my project as a Spring Boot App, my guess is that the solution might not be too complicated:
Log of the error:

I am aware that this does not do much yet, but I would like to run it and open http://localhost:8080 and see the result.
I have tried to look into the buildpath libraries as described in other threads like: disableRegistry() doesn't exist (org.apache.tomcat.util.modeler.Registry), but i would not want to mess with it too much as I am new to this, any help would be much appreciated, thanks!
You put two incompatible versions of tomcat-util among your dependencies:
tomcat-embed-core, which is a transitive dependency of spring-boot-starter-web,tomcat-jasper, which you added separately.You should use embed-tomcat-jasper instead, version 9.0.43. Maven tries to eliminate version conflicts as best as it can, but it doesn't know that tomcat-jasper and embed-tomcat-jasper are the same thing. Since spring-boot-starter-parent manages Tomcat's version, you can (and probably should) omit the version declaration:
<dependency>
<groupId>org.apache.tomcat</groupId>
<artifactId>embed-tomcat-jasper</artifactId>
</dependency>
