I have used --logLevel=debug from command line with liquibase 3.6.1 and I don't see any debug output being generated. Has anyone used 3.6.1 and got this working?
Below is the output I get after executing liquibase command.
Starting Liquibase at Tue, 03 Jul 2018 14:07:10 EDT (version 3.6.1 built at 2018-04-11 08:41:04)
Liquibase: Update has been successful.
The issue has been reported https://liquibase.jira.com/browse/CORE-3220 and there's a pending PR for the fix: https://github.com/liquibase/liquibase/pull/770
Right now you can downgrade the liquibase core version to 3.5.5, it will resolve the issue, I had faced the same issue, after downgrading version to 3.5.5 the issue was resolved.
