Remove Guava dependency and update plugin configurations (#216)

Guava dependency was removed from multiple modules to simplify and reduce project dependencies. Necessary updates were made to tests to replace Guava utilities with standard Java library methods. Additionally, Maven plugin configurations were updated, including the Maven compiler plugin, to ensure compatibility with Java 11 and support for Lombok's annotation processing.
