java: package com.mysql.cj.jdbc does not exist Spring Boot Java

I’m very new to development, and I’m attempting to run an old project on my local machine. However, when I try to run it, I encounter the error message: “java: package com.mysql.cj.jdbc does not exist.” I have configured Java 1.8 in the Project Structure settings, as well as in the Edit Configuration, since it was the version used by the previous developer. Any guidance or assistance on this issue would be greatly appreciated.
