About the version.
Nice, that is really handy. I didn’t pay attention obviously and had set a version number without -SNAPSHOT in it.
I like that feature!
About /apps
Clearly the AppFramework is looking into /apps, as we can see here. And this is where I placed my _app.json file indeed, alongside others that were working perfectly well until now. @darius’s example suggests that it should be in /apps too: /openmrs-module-reportingui/blob/master/omod/src/main/resources/apps/reports_app.json What made you think that the framework was trying to fetch /app, causing an error?
