How to change the remote repository for a git submodule

Question

I ve created a git repository with a submodule in it  I m able to tell the submodule itself to change its remote repository path  but I m not sure how to tell the parent repository how to change the remote repository path for the submodule   I wouldn t be surprised if I m somewhat out of luck and have to do things manually  as even deleting submodules isn t easy

With Git 2 25  Q1 2020   you can modify it  See  Git submodule url changed  and the new command  git submodule set-url  --   lt path gt   lt newurl gt      Original answer  May 2009  ten years ago   Actually  a patch has been submitted in April 2009 to clarify gitmodule role   So now the gitmodule documentation does not yet include      The  gitmodules file  located in the top-level directory of a git working tree  is a text file with a syntax matching the requirements -of linkgit git-config1     NEW     As this file is managed by Git  it tracks the  records of a project s submodules    Information stored in this file is used as a hint to prime the authoritative version of the record stored in the project configuration file    User specific record changes  e g  to account for differences in submodule URLs due to networking situations  should be made to the configuration file  while record changes to be propagated  e g   due to a relocation of the submodule source  should be made to this file    That pretty much confirm Jim s answer     If you follow this git submodule tutorial  you see you need a  git submodule init  to add the submodule repository URLs to  git config    git submodule sync  has been added in August 2008 precisely to make that task easier when URL changes  especially if the number of submodules is important   The associate script with that command is straightforward enough   module list        while read mode sha1 stage path do     name   module name   path       url   git config -f  gitmodules --get submodule   name  url      if test -e   path   git     then               unset GIT DIR         cd   path          remote   get default remote          say  Synchronizing submodule url for   name           git config remote   remote  url   url            fi done   The goal remains   git config remote   remote  url   url

A brute force approach   update the  gitmodules file in the supermodule to point to the new submodule url  add and commit the changes to supermodule  gitmodules  make a new clone of the supermodule somewhere else on your computer  making sure that the latest changes to the  gitmodules file are reflected in the clone   change your working directory to the new clone of the supermodule  run git submodule update --init path-to-submodule on the submodule   et voil    The submodule in the new clone of the supermodule is properly configured

In simple terms  you just need to edit the  gitmodules file  then resync and update   Edit the file  either via a git command or directly   git config --file  gitmodules -e   or just   vim  gitmodules   then resync and update   git submodule sync git submodule update --init --recursive --remote

What worked for me  on Windows  using git version 1 8 3 msysgit 0    Update  gitmodules with the URL to the new repository Remove the corresponding line from the  quot  git config quot  file Delete the corresponding directory in the  quot  git modules external quot  directory   quot  git modules quot  for recent git versions  Delete the checked out submodule directory itself  unsure if this is necessary  Run git submodule init and git submodule update Make sure the checked out submodule is at the correct commit  and commit that  since it s likely that the hash will be different  After doing all that  everything is in the state I would expect  I imagine other users of the repository will have similar pain when they come to update though - it would be wise to explain these steps in your commit message

Just edit your  git config file  For example  if you have a  common  submodule you can do this in the super-module   git config submodule common url  data my local common

You should just be able to edit the  gitmodules file to update the URL and then run git submodule sync --recursive to reflect that change to the superproject and your working copy   Then you need to go to the  git modules path to submodule dir and change its config file to update git path   If repo history is different then you need to checkout new branch manually   git submodule sync --recursive cd  lt submodule dir gt    git fetch git checkout origin master git branch master -f git checkout master
