View AWS CodeCommit URL Helper on the plugin site for more information.
Once you install, set the URL of your Git Repository to the one you got from the AWS CodeCommit Console e.g. https://git-codecommit.us-east-1.amazonaws.com/v1/repos/sample-codecommit-repository, and under Behaviours, add "AWS CodeCommit URL Helper". Also, set the AWS Credential ID on it. Ignore the 403 error, as the plugin behaves only on runtime.
Note that Git binary might need some patching due to gnutls. Alternatively, set your git path to 'jgit' (Manage Jenkins | Configure | git | Git Installations | Path to git executable) in order to switch to the embedded jgit backend. (Ignore the warning on the missing binary)
The plugin detects all matching HTTPS codecommit Repository URLS and once found, adds a generated credential token when needed.
