IntelliJ 15, SpringBoot devtools livereload not working

Question

Having issues with the new LiveReload feature with Spring Boot devtools 1.3. It doesn't reload on class changes. I've seen it demo'd with IntelliJ @ Devoxx 2015. Is there some IDE setting I need to have enabled? I'm running via the IDE and not through Gradle. I tried enabling "Make project automatically" which doesn't seem to help.

It seems to load correctly and is looking in the correct path

I am guessing you are coding and expect DevTools to auto-magically figure out you have changed something in your project? Devtools does that by watching your classpath folder(s). When a .class file (or a resource) has changed, devtools take the appopriate action.

If you don't see anything, that's probably because you're just coding and not updating the classpath. You have to invoke Make Project to update the classpath. See the documentation
