Check your git repo before committing   gitrepo  git hooks commit-msg   if this file is not present in that location then you will get this error  missing Change-Id in commit message     To solve this just copy paste the commit hook in  git folder

Try this   git commit --amend   Then copy and  paste the Change-Id  I55862204ef71f69bc88c79fe2259f7cb8365699a at the end of the file   Save it and push it again

You might be an admin doing a one-off push directly into refs changes  lt change number gt    For example  once a commit without Change-Id landed into Subversion  you pull it out of Subversion using git-svn  and you d like to archive it as a Gerrit patchset into a Gerrit change    If so  you can go to project settings page  http    installation-path    admin projects  project-id   and temporarily change  Require Change-Id in commit message  value to False    Don t forget to afterwards change it back to Inherit or True

I got this error message too   and what makes me think it is useful to give an answer here is that the answer from  Rafal Rawicki is a good solution in some cases but not for all circumstances  example that i met   1 run  git log  we can get the HEAD commit change-id  2 we also can get a  HEAD  commit change-id on Gerrit website   3 they are different  which makes us can not push successfully and get the  missing change-id error    solution   0  git add     1 save your HEAD commit change-id got from  git log  it will be used later   2 copy the HEAD commit change-id from Gerrit website   3  git reset HEAD   4  git commit --amend  and copy the change-id from   Gerrit website   to the commit message in the last paragraph replace previous change-id   5  git push    you can push successfully now but can not find the HEAD commit from   git log   on Gerrit website too  6  git reset HEAD   7  git commit --amend  and copy the change-id from   git log   we saved in step 1  to the commit message in the last paragraph replace previous change-id   8  git push    you can find the HEAD commit from   git log   on Gerrit website they have the same change-id  9 done

Check if your commits have Change-Id      in their descriptions  Every commit should have them   If no  use git rebase -i to reword the commit messages and add proper Change-Ids  usually this is a SHA1 of the first version of the reviewed commit    For the future  you should install commit hook  which automatically adds the required Change-Id   Execute scp -p -P 29418 username your gerrit address hooks commit-msg  git hooks  in the repository directory or download them from  http   your gerrit address tools hooks commit-msg and copy to  git hooks

You need to follow below 2 steps instructions    Issue  remote  Hint  To automatically insert Change-Id  install the hook   1  gitdir   git rev-parse --git-dir     2  scp -p -P 29418  lt username gt  gerrit xyz se hooks commit-msg   gitdir  hooks   normally  gitdir     git   You need to update the username and the Gerrit link

This can also happen if you have this restriction      Please enter the commit message for your changes  Lines starting with     will be ignored  and an empty message aborts the commit    and you do like me  write a commit message starting with            I had the same error  but I already had the commit-msg and did the rebase and everything  Very silly mistake though  D

under my  git hooks folder  some sample files were missing  like commit-msg post-commit sample post-update sample   adding these files resolved my change id missing issue

User · Answer

It is because Gerrit is configured to require Change-Id in the commit messages   http   gerrit googlecode com svn-history r6114 documentation 2 1 7 error-missing-changeid html  You have  to change the messages of every commit that you are pushing to include the change id   using git filter-branch   and only then push

We solved this issue this morning by re-cloning repository and re-applying changes  This is the simplest way to re-sync your local copy with Gerrit  As always we created a backup first    Although there are a number of other wildly complicated solutions  its often advantageous to take a simple approach to avoid making things worse

User · Answer

If you need to add Change-Id to multiple commits  you can download the hook from your Gerrit server and run these commands to add the Change-Ids to all commits that need them at once   The example below fixes all commits on your current branch that have not yet been pushed to the upstream branch   tmp   mktemp  hook   readlink -f   git rev-parse --git-dir   hooks commit-msg git filter-branch -f --msg-filter  cat  gt   tmp     hook    tmp  cat  tmp    u   HEAD
