# Update a comment

`PUT /groups/{groupId}/artifacts/{artifactId}/versions/{version}/comments/{commentId}`

## Request

- The document declares no server URL.
- Auth: none declared

Updates the value of a single comment in an artifact version.  Only the owner of the
comment can modify it.  The `artifactId`, unique `version` number, and `commentId` 
must be provided.

This operation can fail for the following reasons:

* No artifact with this `artifactId` exists (HTTP error `404`)
* No version with this `version` exists (HTTP error `404`)
* No comment with this `commentId` exists (HTTP error `404`)
* A server error occurred (HTTP error `500`)

## Request body

## Response `204`

The value of the comment was successfully changed.
