Why is IDEA recompiling golang project when I simply restart a debug session

I've just started playing with IDEA support for go and one thing I noticed is that whenever I debug my app,
simply restarting the debug session causes a recompilation although nothing has changed in the code.

I've checked the debug config and there's no indication that a recompile/build is required before the debug starts

Anyone knows why this is or how to change this so it does not happen?

The compilation cycle is quick(ish) right now, but I can see that when the app grows, it'll take longer and seems counter productive.

Cheers,

Bonny
