How can I update git sub modules in SourceTree?
I couldn't find the answer myself, so I created a custom action. Go to Preferences, Custom Actions, and enter the following info: (This is on a Mac. Your path to the git executable may vary.)
Just double-click on the submodule or left-click and open the module
Once in the submodule, the UI is like any git repo , press on pull/fetch to update to the header. And voila.
Here is the windows version:
This command assumes the location of your sh.exe - depending on how you setup SourceTree it could be somewhere else.
/c %LOCALAPPDATA%\Atlassian\SourceTree\git_local\bin\sh.exe --login -i -c "git submodule update"""
Not sure whether it is a bug - but in the version of Sourcetree I am using (v1.6.14.0) I found that having the extra pair of quotations "" on the end was required - otherwise an extra quotation exists and the unbalanced statement then causes sh to bark:
cmd "/c %LOCALAPPDATA%\Atlassian\SourceTree\git_local\bin\sh.exe --login -i -c "git submodule update""
sh: unexpected EOF while looking for matching `"'
sh: syntax error: unexpected end of file
Completed with errors, see above.
The link provided by Isuru does include how to perform update (look for "Change the submodule commit which your repository is tracking")
In short, on the main repository,
- choose the submodules dropdown
- double click the submodule you want to update - you will switch focus to the submodule
- pull (latest) or checkout (specific commit) the required update
- go back to the tab for the main repository
- there will be an uncommitted change (which submodule commit to use) in the main repository
- commit and push the change
