Vim-plug: Cannot load local plugin

[meain]

I added the directory in init.vim as

Plug '~/Documents/Projects/vim-test'

and ran :PlugInstall but it is not loading the plugin.

Folder structure is like a vim plugin structure

└── syntax
    └── test.vim

vim-plug can load the plugin directly from the directory without copying it, so there's no installation. If you do want it to be copied, you can write it in absolute path with file:// prefix.

Plug 'file:///Users/jg/foo/bar'

" or if you don't want to hard-code home directory
Plug 'file://'.expand('~/foo/bar')

This no longer works.

It works fine so far:

call plug#begin('~/.local/share/nvim/plugged')

" work fine
Plug 'file://'.expand('~/.local/share/nvim/plugged/my_plug') 

" not work!!!
Plug 'file://'.expand('~/dev_pluggins/my_plug') 

call plug#end()
