IntelliJ IDEA 14 and scratch files

[e1senh0rn]

I have IDEA 14 Ultimate, build 139.224. Cursive installed as a plugin, version 0.1.41.
When I go to Tools -> New Scratch File... and select Clojure, new scratch file appears.
I type

(println "hello")

and receive this exception:

[jstaffans]

👍 I would like to be able to use scratch files as well.

[lenaschoenburg]

👍 Even cooler If we could evaluate that in a scratch repl.

[cursive-ide]

I've investigated this, it appears to be a problem with the way scratch files are implemented. I've created an issue here.

[henryw374]

wrt evaluating scratch files, create a *.clj file in the scratches directory/area ... ie create via r-click->New-> clojure ns in the scratch area, instead of tools->new scratch

eval works from *.clj files!

[cursive-ide]

This exception is fixed, but unfortunately the problems with the way scratch files are implemented remain, which means that it's impossible to create scratch CLJS, CLJC or EDN files. But at least the Clojure ones should be more usable.
