As part of my personal education on multi-module Maven projects, I just completed a walk through a Liberty guide: https://openliberty.io/guides/maven-multimodules.html which teaches readers how to build a multi-module application for Open Liberty.

The finished application will be an excellent example that we can use as a reference in the development of multi-module Maven features and can eventually be used in LTI's automated testing. When I loaded the this project into the current LTI plug-in I was able to use it to start dev mode and observed the application being refreshed as I made changes to source in the editor.

Of course there's still work to do. LTI is including the EAR project in the dashboard and if you try to start dev mode from that project it currently fails. Should the EAR project be in that view at all? That's one of the questions we'll want to answer as we move forward.
