Don't display *compilation* buffer in Emacs until the process exits with error or warning

Looks like you can achieve what you want through temporarily disabling display-buffer across compilation-start.

This is a combination of what sds said and something posted on the comments @ here

The comment there had a nasty problem with point jumping in the original source buffer that I appear to have worked out by also blocking set-window-point and goto-char. It feels like a dirty hack, but is working so far. YMMV!

(defun brian-compile-finish (buffer outstr)
  (unless (string-match "finished" outstr)
    (switch-to-buffer-other-window buffer))
  t)

(setq compilation-finish-functions 'brian-compile-finish)

(require 'cl)

(defadvice compilation-start
  (around inhibit-display
      (command &optional mode name-function highlight-regexp)) 
  (if (not (string-match "^\\(find\\|grep\\)" command))
      (flet ((display-buffer)
         (set-window-point)
         (goto-char)) 
    (fset 'display-buffer 'ignore)
    (fset 'goto-char 'ignore)
    (fset 'set-window-point 'ignore)
    (save-window-excursion 
      ad-do-it))
    ad-do-it))

(ad-activate 'compilation-start)

Now you should see that all compile buffers will only be shown if outstr doesn't return a successful finish status OR the invoked command started with "find" or "grep."

I edited @assem's answer to use cl-letf instead of flet.

(defun brian-compile-finish (buffer outstr)
  (unless (string-match "finished" outstr)
    (switch-to-buffer-other-window buffer))
  t)

(setq compilation-finish-functions 'brian-compile-finish)

(defadvice compilation-start
  (around inhibit-display
      (command &optional mode name-function highlight-regexp))
  (if (not (string-match "^\\(find\\|grep\\)" command))
      (cl-letf ((display-buffer   #'ignore)
                (set-window-point #'ignoreco)
                (goto-char        #'ignore))
        (save-window-excursion
          ad-do-it))
    ad-do-it))

(ad-activate 'compilation-start)

(provide 'only-display-compile-on-error)
