The purpose of this action is to backport commits between branches.

When a label following the convention backport-{branch} is added to a merged Pull Request, the action will try to cherry pick all the commits associated to the labeled Pull Request and open a new Pull Request to the target {branch} with the commits to apply.

If the backport is not possible due to conflicts, the action will make a comment in the original Pull Request that the backport failed, and it must be handled manually.

Required The GitHub Token used to create an authenticated client. The Github Token is already set by the Github Action itself. Use this if you want to pass in your own Personal Access Token.

          GIT_COMMITTER_NAME: ${{ env.GITHUB_ACTOR }}
          GIT_COMMITTER_EMAIL: [email protected]

The GIT_COMMITTER_NAME and GIT_COMMITTER_EMAIL are used for the name and email of the cherry pick committer. The action maintains the original committer author. These options are optional.

It is also possible to use the Backport Action directly from your local environment or with any other CI. Please refer to backport.java. This requires JBang to run the script.

The same rules apply. The target Pull Request require backport labels and the script will either create backport Pull Request or report issues.

jbang backport.java <token> <repository> <pullRequestNumber>
