|  | = commit xxxxxxx: missing Change-Id in message footer | 
|  |  | 
|  | With this error message Gerrit rejects to push a commit to a project | 
|  | which is configured to always require a Change-Id in the commit | 
|  | message if the commit message of the pushed commit does not contain | 
|  | a Change-Id. | 
|  |  | 
|  | You can see the commit messages for existing commits in the history | 
|  | by doing a link:http://www.kernel.org/pub/software/scm/git/docs/git-log.html[git log,role=external,window=_blank]. | 
|  |  | 
|  | To avoid this error you should use the link:cmd-hook-commit-msg.html[commit hook] or EGit to | 
|  | automatically create and insert a unique Change-Id into the commit | 
|  | message on every commit. | 
|  |  | 
|  |  | 
|  | == Missing Change-Id in the commit message | 
|  |  | 
|  | If the commit message of a commit that you want to push does not | 
|  | contain a Change-Id you have to update its commit message and insert | 
|  | a Change-Id. | 
|  |  | 
|  | If you want to upload a new change to Gerrit make sure that you have | 
|  | configured your environment so that a unique Change-Id is | 
|  | automatically created and inserted on every commit as explained | 
|  | above. Now you can rewrite the commits for which the Change-Ids are | 
|  | missing and the Change-Ids will be automatically created and inserted | 
|  | into the commit messages. This is explained link:error-push-fails-due-to-commit-message.html#commit_hook[here]. | 
|  |  | 
|  | If you want to update an existing change in Gerrit by uploading a new | 
|  | patch set you should copy its Change-Id from the Gerrit Web UI and | 
|  | insert it into the commit message. How to update the commit message | 
|  | is explained link:error-push-fails-due-to-commit-message.html[here]. |
