Gradle can fail due to left-over Emacs back up files


(Howard Lewis Ship) #1

I’m seeing this failure in my build:

It seems to be due to a dangling file left behind by Emacs:

I think Gradle should recognize this and ignore the file (a link to non-existent file) and, at most, emit a warning. Perhaps it should even handle this as a special case, to support Emacs users?

It seems that ‘.#metric.clj’ is a symlink to a non-existent file. In fact it looks like some server coordinates. Does emacs encode the server connection to your nrepl process like this?
