I keep getting this message:
29-Jul-2021 12:54:23.839 WARN [RMI TCP Connection(3)-127.0.0.1] org.hibernate.boot.internal.SessionFactoryOptionsBuilder. class org.hibernate.tool.schema.Action cannot be cast to class java.lang.String (org.hibernate.tool.schema.Action is in unnamed module of loader org.apache.catalina.loader.ParallelWebappClassLoader @1a92892d; java.lang.String is in module java.base of loader 'bootstrap') Ignoring
Why does it appear? How can I fix this?
Below is my entire project.
