Update a submodule to the latest commit

Question

I have a project A which is a library and it is used in a project B   Both projects A and B have a separate repository on github BUT inside B we have a submodule of A   I edited some classes on the library  which is in the repo A  I pushed on the remote repo  so the library  repo A  is updated   These updates do not reflect on the  reference   the submodule  the submodule refers to a previous commit     what should I do in order to update the submodule on git

My project should use the  latest  for the submodule  On Mac OSX 10 11  git version 2 7 1  I did not need to go  into  my submodule folder in order to collect its commits  I merely did a regular   git pull --rebase    at the top level  and it correctly updated my submodule

If you update a submodule and commit to it  you need to go to the containing  or higher level repo and add the change there   git status   will show something like   modified     some path to your submodule   The fact that the submodule is out of sync can also be seen with  git submodule   the output will show    afafaffa232452362634243523 some path to your submodule   The plus indicates that the your submodule is pointing ahead of where the top repo expects it to point to   simply add this change   git add some path to your submodule   and commit it   git commit -m  referenced newer version of my submodule    When you push up your changes  make sure you push up the change in the submodule first and then push the reference change in the outer repo  This way people that update will always be able to successfully run  git submodule update   More info on submodules can be found here http   progit org book ch6-6 html

A few of the other answers recommend merging committing within the submodule s directory  which IMO can become a little messy   Assuming the remote server is named origin and we want the master branch of the submodule s   I tend to use   git submodule foreach  git fetch  amp  amp  git reset --hard origin master   Note  This will perform a hard reset on each submodule -- if you don t want this  you can change --hard to --soft

None of the above answers worked for me  This was the solution  from the parent directory run  git submodule update --init  cd submodule-directory  git pull  cd     git add submodule-directory   now you can git commit and git push

Enter the submodule directory     cd projB projA   Pull the repo from you project A  will not update the git status of your parent  project B      git pull origin master   Go back to the root directory  amp  check update   cd    git status   If the submodule updated before  it will show something like below       Not currently on any branch    Changed but not updated       use  git add      to update what will be committed       use  git checkout --      to discard changes in working directory            modified    projB projA  new commits      Then  commit the update     git add projB projA git commit -m  projA submodule updated      UPDATE  As  paul pointed out  since git 1 8  we can use  git submodule update --remote --merge   to update the submodule to the latest remote commit  It ll be convenient in most cases

Andy s response worked for me by escaping  path   git submodule foreach   git checkout master  git pull  cd     git add   path  git commit -m  Submodule Sync

Since git 1 8 you can do  git submodule update --remote --merge   This will update the submodule to the latest remote commit  You will then need to commit the change so the gitlink in the parent repository is updated  git commit   And then push the changes as without this  the SHA-1 identity the pointing to the submodule won t be updated and so the change won t be visible to anyone else
