No error notification when syncing projects and "lein" can't be found

It would be nice if a small Tooltip could be shown if project synchronization fails.

I just get this exception in idea.log which makes it clear what I need to do, but I was wondering why nothing seemed to happen for a while.

What was the fix to this? I am getting the same error but can't seem to resolve it.
