I am using submodule to control my plugin in MacVim.
When I tried to update the submodule using git update submodule
It comes out:
fatal: destination path 'bundle/ShowMark' already exists and is not an empty directory.
Clone of 'git://github.com/vim-scripts/ShowMarks.git' into submodule path 'bundle/ShowMark' failed
I tried my own solution:
remove the directory and then git update submodule
It works but the MacVim cannot run properly. MacVim cannot open any new/old files.
