Hi all, I've been trying to integrate Liquibase into a module and I'm seeing some odd behaviour. When I use Liquibase 4.x.x in the module I get an exception that there is no default logger available. However if I just build a standalone Java jar it works fine. My understanding is that Liquibase hooks into java.util.logging. Could it be that java.util.logging simply isn't available when running inside an Ignition module? ---

It isn't. Modules are supposed to use SLF4J or work with Ignition's LoggerEx framework. ---

Your module will probably need to include the [jul-to-slf4j bridge](https://www.slf4j.org/legacy.html#jul-to-slf4j).
