Some refactorings are not working via TRAMP

[vlnn]

Expected behavior

When using Cider connected to nrepl running on ssh host, refactors of the clojure code should work.

Actual behavior

Some of the refactors are not working, returning errors.

Steps to reproduce the problem

On remote host:

lein new test-clj-refactor
cd test-clj-refactor
lein repl :start :port 11111

On local host:

1. Start doom emacs
2. Create new project with remote ssh dir as a root one SPC p a + /ssh:target-host:tmp/test-clj-refactor
3. Connect to this project with SPC p p
4. Open src/test-clj-refactor/core.clj
5. Connect to nrepl via ssh: SPC m c + target-host + 11111 (you should see successful message in new repl window)
6. In core.clj move cursor to any form (e.g. println one from the test) and press SPC m R t ef to extract the function. You should see the error as shown below. Other refactors may work (e.g. extract as def works OK).

Thanks!

I'll see what I can do.

btw, it looks like you could upgrade cider (which most recent snapshots have a superior TRAMP support: jump-to-definition will work more reliably) and the JDK (8 is being increasingly unsupported in the Clojure community - CIDER will certainly drop it)

[vemv]

Done and tried it myself with a local TRAMP connection.

New MELPA (stable and snapshot) releases will be available within 1-2 hours.
