Greetings all. I am encountering an odd situation I cannot fathom.
I am using JDK 17 and Wildly 28.
Said module is a dependency in a WAR's \WEB-INF\jboss-deployment-struncture.xml file. (module-info is also in effect, the project imports the jar's packages; compiles ok).
During deployment I'm getting errors I do not understand as the module is there (I've deployed JDBC drivers before so comfortable with that process).
What might I have missed?

DOH! My bad: the module.xml had an error and the server wasn't saying anything.
Had to get into jboss-cli in order to scan the module subsystem and see that it didn't exist.
