no new changes

https://gerrit-documentation.storage.googleapis.com/Documentation/2.16.4/error-no-new-changes.html

With this error message Gerrit rejects to push a commit if the pushed commit was already successfully pushed to Gerrit in project scope. In this case there is no new change and consequently there is nothing for Gerrit to do.

If your push is failing with this error message, you normally don’t have to do anything since the commit was already successfully pushed. Still this error message may sometimes come as a surprise if you expected a new commit to be pushed. In this case you should verify that:

1. your changes were successfully committed locally (otherwise there is no new commit which can be pushed)

2. you are pushing the correct commit (e.g. if you are pushing HEAD make sure you have locally checked out the correct branch)
