I think this can only occur when we're able to locate an SDK, but we have issues starting up the analysis server.

[nmccready]

This is correct and can be possibly closed. A better error would be missing SDK. Anyway installing the sdk via homebrew resolved this.

Just ran into this too. I still don't know what to do... I'm guessing it's something with my setup, but a better message would definitely help.

[devoncarew]

I'll improve the messaging. You can verify which sdk the plugin is using by running the command 'show sdk info' (from atom's command pallette). We try to auto-detect the sdk. If we can't you can add a path manually in the plugin's settings.

You'll want a 1.13 SDK if possible, to capture a bunch of fixes in the analysis server.
