Troubleshooting "Unable to load authentication plugin 'caching_sha2_password'" Error

Eclipse users may encounter the error "Could not discover the dialect to use. java.sql.SQLException: Unable to load authentication plugin 'caching_sha2_password'." when starting their application.

Cause:

This error occurs because starting with MySQL 8.0.4, the default authentication plugin has changed from "mysql_native_password" to "caching_sha2_password."

Solution:

To resolve the issue, you can change the authentication plugin to "mysql_native_password" for specific users using the following ALTER USER command:

ALTER USER 'username'@'hostname' IDENTIFIED WITH mysql_native_password BY 'password';

For example, if your username is "student" and password is "pass123", you would run the following command:

ALTER USER 'student'@'localhost' IDENTIFIED WITH mysql_native_password BY 'pass123';

Remember to replace "username," "hostname," and "password" with the appropriate values.
