Unknow option javacomplete#complete when using vim to edit java files

Question

I have set omnifuc in my .vimrc file :

setlocal omnifunc = javacomplete#complete

Then the exception comes out when i editing any file :

E518: Unknown option: javacomplete#complete

Answer 1

Remove the space after the =. With this space vim is interpreting the javacomplete#complete as a vim option.

Here is an excerpt from vim's help on :set-args:

:se[t] {option}={value}

                           ...

                           White space between {option} and '=' is allowed and
                           will be ignored.  White space between '=' and {value}
                           is not allowed.
