Would be nice to see some tests around this if possible. Otherwise looks ok.

@mherman22 does this work if I pass invalid credentials using this command:

org.openmrs.maven.plugins:openmrs-sdk-maven-plugin:6.1.0-SNAPSHOT:setup -DdbUri=jdbc:mysql://localhost:3306/@DBNAME@ -DdbDriver=mysql -DdbUser=root -DdbPassword=wrongPassword

Fails with [ERROR] Failed to execute goal org.openmrs.maven.plugins:openmrs-sdk-maven-plugin:6.1.0-SNAPSHOT:setup (default-cli) on project openmrs-sdk: Failed to setup server: Failed to connect to database after 3 attempts. Please verify your credentials and try again. Invalid database credentials. Please check your username and password. Access denied for user 'root'@'localhost' (using password: YES) -> [Help 1]

And with that error, it should prompt the user for new credentials until they get it right(limitd to 3 attempts

Yeah. It would be better if we could avoid the whole error message and just output something like the following:

Database connection failed (attempt 1 of 3): Invalid database credentials. Please check your username and password.
