3. Steps to reproduce

I reproduce the problem in a version of Sublime Text without plugins and user settings.

I install SublimeGrunt → I restart Sublime Text → I open any file in my project with Gruntfile.coffee file → Ctrl+Shift+P (⌘⇧p for Mac) → Grunt.

4. Expected behavior

I successful build my project in terminal:

D:\Kristinita>grunt build
Running "shell:generate" (shell) task
Done: Processed 0 articles, 0 drafts, 14 pages and 0 hidden pages in 10.53 seconds.

Running "move:favicons" (move) task
>> 10 files or directories moved, 0 failed.

Running "move:roothtml" (move) task
>> 3 files or directories moved, 0 failed.

Running "move:extra" (move) task
>> 7 files or directories moved, 0 failed.

Running "clean:0" (clean) task
>> 1 path cleaned.

Running "clean:1" (clean) task
>> 1 path cleaned.

Running "clean:2" (clean) task
>> 1 path cleaned.

Running "replace:replacehtml" (replace) task

Done.

5. Actual behavior

My build is not success, I get stack trace in Sublime Text console:

command: grunt
Traceback (most recent call last):
  File "D:\Sublime Text Build 3126 x64 For Debug\sublime_plugin.py", line 797, in run_
    return self.run()

    if data[self.chosen_gruntfile]["sha1"] == filesha1:
KeyError: 'D:\\Kristinita\\Gruntfile.coffee'
