Fix Gerrit Error: Missing Change-Id in Git Commit Messages

If you're working with Gerrit, you may have encountered the error message "missing Change-Id in commit message footer" when trying to push your changes for review. This error occurs because Gerrit requires a unique Change-Id for each change and it must be included in the commit message footer.

To fix this error, you need to add the Change-Id to your commit message. The Change-Id is a unique identifier that is generated by Gerrit and is used to track changes and reviews in Gerrit.

Here are the steps to add the Change-Id to your commit message:

1. Make sure you have the Change-Id hook installed in your local git repository. You can check this by running the command: grep -i change-id .git/hooks/commit-msg.
2. If the hook is not installed, you can download it from the Gerrit server by running the command: scp -p -P 29418 <username>@<gerrit-server>:hooks/commit-msg .git/hooks/.
3. Open your commit message file in an editor.
4. Add the following line to the end of your commit message footer: Change-Id: <generated-id>.
5. The <generated-id> is the unique identifier generated by Gerrit. You can find this by running the command: git log -1 --pretty=format:%s,%b | grep Change-Id.
6. Save and close the file.
7. Amend your commit by running the command: git commit --amend.
8. Push your changes for review: git push origin HEAD:refs/for/<branch>.

With these steps, you should be able to add the Change-Id to your commit message and avoid the "missing Change-Id in commit message footer" error in Gerrit.
