Tomcat "no method found" error on server startup

Matthew :

I'm currently working on a Spring dynamic web project. On Tomcat startup, I get the following error:

SEVERE: StandardWrapper.Throwable
java.lang.NoSuchMethodError: org.springframework.core.io.ResourceEditor.<init> 
(Lorg/springframework/core/io/ResourceLoader;)V

I have viewed several other questions regarding this issue, and the suggested problem is a dependency issue. I went and changed the version of springframework.core to a previous version, but this changed nothing.

How do I fix this problem? How do I diagnose an issue like this accurately in the future?

You have a mess in your dependencies. I see Spring Boot dependency. Are you trying to create Spring Boot project? If so, go to https://start.spring.io Also most important thing with Spring is to make sure that all base Spring libraries have the same version. To help you with that Maven BOM mechanism exists (btw. similar technique is used in Spring Boot): https://www.baeldung.com/spring-maven-bom
