Spring Boot - 2.3.4
LiquibaseProperties.java doesn't contain driverClassName property.
During LiquibaseAutoConfiguration instantiation, createNewDataSource method takes only url, username, password properties while relying on default driver classname for a given database type.
For our use case, we need to use MySQL 5.1 driver which doesn't have com.mysql.cj.jdbc.Driver class to load hence the only way to get around this issue is by creating your own LiquibaseDataSource bean.
It would be a nice to have feature to avoid creating this bean manually.
Thanks in advance

I wondered if we'd have the same problem with Flyway, but that doesn't appear to be the case. When Flyway is configured with a URL, username, and password it uses its own logic to figure out the driver class. With MySQL it'll try com.mysql.cj.jdbc.Driver first. If that class fails to load, it will fall back to com.mysql.jdbc.Driver. An alternative to providing a property would be for us to do something similar. Another option is to leave things as they are, requiring the creation of a @LiquibaseDataSource bean, as I suspect this is quite an unusual requirement.

@wilkinsona I'd like to work on this.

Thanks for the offer, @evgeniycheban. That'd be great. We've decided to go with @gurpreetsingh85's suggestion and add a driverClassName property to LiquibaseProperties and use it when creating the Liquibase-specific DataSource. Please let us know if you have any questions while working on the necessary changes.
