MPLABX 5.15 Navigation, Autocomplete not working
I've created a new standalone Harmony project, which compiles and runs, but I can't use Navigation (Goto Declaration, etc.) to navigate to another source file and code autocomplete does not work. When I load up a Harmony demo app, everything works just fine so it seems to be a problem with my project, not MPLAB.
What do those functions rely on?
I've tried adding pretty much every source folder I can think of to Project Properties, General, Source Folders and I've cleared the cache folder.
I'm using MacOS 10.14.3, XC32 v2.15 (also tried 2.10). I also tried MPLABX 5.10 with the same results.
