There currently doesn't appear to be a way to modify the loglevel when using the Ant integration tasks for liquibase as there is for from the commandline, i.e. '--logLevel <>'
I tried creating a prop file with the loglevel setting - this does not seem to work with the Ant tasks, although I'm not sure what the "current directory" means in that context.
There is already a logLevel ant property that allows setting what level liquibase logs at.
It appears from the documentation that the updateDatabase target should support an attribute logLevel
But when added I am getting
updateDatabase doesn't support the "logLevel" attribute
An example :
promptOnNonLocalDatabase="Warning : Altering remote DB"
Without logLevel it is working fine but since upgrading from Version 2.x there is a log point for every SQL query generated.
