How to set local buffer variable from Eval: to .dir-local.el?

Question

Why does it work

((nil . ((compilation-directory . "/home/vava/code_directory/")
         (compilation-command . "rake"))
))

and is it not?

((nil . ((Eval . (setq compilation-directory "/home/vava/code_directory"))
         (compilation-command . "rake"))
))

What am I doing wrong here?

I installed enable-local-evalin .emacs.

Answer 1

Emacs Lisp is case sensitive: try the lowercase "eval":

((nil . ((eval . (setq compilation-directory "/home/vava/code_directory"))
         (compilation-command . "rake"))))

Also, the file name for local directory variables is -.dir-locals.el, not .dir-local.el, as in the title of the question.
