git: how to merge commits from a remote to a different path?

问题

I have a git repository with remote foo.

foo is a web app, is contains some files and dirs directly in its root:

Rakefile
app
...
public
script

My main git repository is a larger system which comprises this web app. I want to pull the commits from foo, but I need the files to reside inside the web dir. So they should become web/app, web/public, etc.

I don't want to use foo as a submodule. I want to merge foo into the main repository and then get rid of it.

The up-to-date resources for subtree merging are:

• Git Book chapter6.7
• How to use the subtree merge strategy
• GitHub article "Working with subtree merge"

Cite from How to use the subtree merge strategy:

In this example, let’s say you have the repository at /path/to/B (but it can be an URL as well, if you want). You want to merge the master branch of that repository to the dir-B subdirectory in your current branch.

Here is the command sequence you need:

$ git remote add -f Bproject /path/to/B
$ git merge -s ours --no-commit Bproject/master
$ git read-tree --prefix=dir-B/ -u Bproject/master
$ git commit -m "Merge B project as our subdirectory"

$ git pull -s subtree Bproject master
