BatchDescribeMergeConflicts

Returns information about one or more merge conflicts in the attempted merge of two commit specifiers using the squash or three-way merge strategy.

Request Syntax

{ "conflictDetailLevel": "string", "conflictResolutionStrategy": "string", "destinationCommitSpecifier": "string", "filePaths": [ "string" ], "maxConflictFiles": number, "maxMergeHunks": number, "mergeOption": "string", "nextToken": "string", "repositoryName": "string", "sourceCommitSpecifier": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

conflictDetailLevel

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

Type: String

Valid Values: FILE_LEVEL | LINE_LEVEL

Required: No

conflictResolutionStrategy

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 will be successful.

Type: String

Valid Values: NONE | ACCEPT_SOURCE | ACCEPT_DESTINATION | AUTOMERGE

Required: No

destinationCommitSpecifier

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

Type: String

Required: Yes

filePaths

The path of the target files used to describe the conflicts. If not specified, the default is all conflict files.

Type: Array of strings

Required: No

maxConflictFiles

The maximum number of files to include in the output.

Type: Integer

Required: No

maxMergeHunks

The maximum number of merge hunks to include in the output.

Type: Integer

Required: No

mergeOption

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

Type: String

Valid Values: FAST_FORWARD_MERGE | SQUASH_MERGE | THREE_WAY_MERGE

Required: Yes

nextToken

An enumeration token that when provided in a request, returns the next batch of the results.

Type: String

Required: No

repositoryName

The name of the repository that contains the merge conflicts you want to review.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 100.

Pattern: [\w\.-]+

Required: Yes

sourceCommitSpecifier

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

Type: String

Required: Yes
