How to use ansible to provision vim vundle plugin?

Question

I use vundle as plugin manager for vim. And I want to use ansible to automate vundle plugin installation.

But I just can't get ansible to do provision automatically:

- name: install vundle plugin
  shell: vim +PluginInstall +qall

above is the ansible playbook YML file for vim. When ansible start to run this task, it just goes on forever, it never ends and it never fails. Until I force it to stop by CTRL C.

If I run that command directly in the guest os, it works fine, vim shows up and finishes installation.

What's the problem here?

==========================================
Edit:

After read Roy Zuo's answer, and turn on verbose mode of vim, I tried the following command:

vim -E -s -c "source ~/.vimrc" +PluginInstall +qall -V

and below is the output:

It seems vim stopped when it can't find the plugin specified in .vimrc. Any idea how to continue?

You would want vim in this case to run in EX mode which avoids bringing up the visual interface which requires a tty for display. Try the following command instead.

vim -E -s -c "source ~/.vimrc" -c PluginInstall -c qa

Here -E tells vim to start in EX mode, and "-s" (only available in EX mode, help -s-ex) means we want it to run silently without any prompts or informative messages. Moreover, without sourcing your runtime file, EX mode does not know how to execute PluginInstall command.

 -s         Silent or batch mode.  Only when Vim was started as "ex" or
            when preceded with the "-e" argument.  Otherwise see -s,
            which does take an argument while this use of "-s" doesn't.
            To be used when Vim is used to execute Ex commands from a file
            instead of a terminal.  Switches off most prompts and
            informative messages.  Also warnings and error messages.
            The output of these commands is displayed (to stdout):
                    :print
                    :list
                    :number
                    :set      to display option values.

====================

As for your Solarized color scheme missing, since you are already with Vundle, it is easy to have the following in your vimrc.

Plugin 'altercation/vim-colors-solarized'

and you should make sure colorscheme solarized line come after it.
