[ aws . codecommit ]



Creates an unreferenced commit that represents the result of merging two branches using a specified merge strategy. This can help you determine the outcome of a potential merge. This API cannot be used with the fast-forward merge strategy because that strategy does not create a merge commit.


This unreferenced merge commit can only be accessed using the GetCommit API or through git commands such as git fetch. To retrieve this commit, you must specify its commit ID or otherwise reference it.

--repository-name (string)

The name of the repository where you want to create the unreferenced merge commit.

--source-commit-specifier (string)

The branch, tag, HEAD, or other fully qualified reference used to identify a commit (for example, a branch name or a full commit ID).

--destination-commit-specifier (string)

The branch, tag, HEAD, or other fully qualified reference used to identify a commit (for example, a branch name or a full commit ID).

--merge-option (string)

The merge option or strategy you want to use to merge the code.

Possible values:


--conflict-detail-level (string)

The level of conflict detail to use. If unspecified, the default FILE_LEVEL is used, which returns a not-mergeable result if the same file has differences in both branches. If LINE_LEVEL is specified, a conflict is considered not mergeable if the same file in both branches has differences on the same line.

Possible values:


--conflict-resolution-strategy (string)

Specifies which branch to use when resolving conflicts, or whether to attempt automatically merging two versions of a file. The default is NONE, which requires any conflicts to be resolved manually before the merge operation is successful.

Possible values:

  • NONE

--author-name (string)

The name of the author who created the unreferenced commit. This information is used as both the author and committer for the commit.

--email (string)

The email address for the person who created the unreferenced commit.

--commit-message (string)

The commit message for the unreferenced commit.

--keep-empty-folders | --no-keep-empty-folders (boolean)

If the commit contains deletions, whether to keep a folder or folder structure if the changes leave the folders empty. If this is specified as true, a .gitkeep file is created for empty folders. The default is false.

--conflict-resolution (structure)

If AUTOMERGE is the conflict resolution strategy, a list of inputs to use when resolving conflicts during a merge.

Shorthand Syntax:


JSON Syntax:

  "replaceContents": [
      "filePath": "string",
      "content": blob,
      "fileMode": "EXECUTABLE"|"NORMAL"|"SYMLINK"
  "deleteFiles": [
      "filePath": "string"
  "setFileModes": [
      "filePath": "string",
      "fileMode": "EXECUTABLE"|"NORMAL"|"SYMLINK"

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.


To create an unreferenced commit that represents the result of merging two commit specifiers

The following create-unreferenced-merge-commit example creates a commit that represents the results of a merge between a source branch named bugfix-1234 with a destination branch named master using the THREE_WAY_MERGE strategy in a repository named MyDemoRepo.

aws codecommit create-unreferenced-merge-commit \
    --source-commit-specifier bugfix-1234 \
    --destination-commit-specifier master \
    --merge-option THREE_WAY_MERGE \
    --repository-name MyDemoRepo \
    --name "Maria Garcia" \
    --email "" \
    --commit-message "Testing the results of this merge."

    "treeId": "389765daEXAMPLE"

For more information, see Resolve Conflicts in a Pull Request in the AWS CodeCommit User Guide.


commitId -> (string)

The full commit ID of the commit that contains your merge results.

treeId -> (string)

The full SHA-1 pointer of the tree information for the commit that contains the merge results.
