JIRA REST API - adding a comment with newline character(s)

Following the example on [https://developer.atlassian.com/display/JIRADEV/JIRA+REST+API+Example+-+Add+Comment], I cannot add a comment contailing a \n newline character. I always receive

POST returned a response status of 400 Bad Request

when attempting to add the comment either using the first or secont approach.

Removing newlines from a larger comment makes it significantly illegible - therefore my question - why is that happening?

Many thanks for any suggestions or ideas!

Try adding one more \ before \n to make \n escape, It worked for me, I added a slash before \n and executed.

Hope this helps.

Hi Nitram!

(1) the <br> does not work as it essentially gets excaped,

(2) the \\ (I've seen also \\\\ in one post) does not work either,

but finally

(3) escaping the \n by \\\\n (four slashes; in Java) DOES WORK!!!! :)

comment.replaceAll("\n", "\\\\n")

Many thanks for your insight!

(hope this thread becomes easily googleable for those having the same problem).


Try the following,

check whether your comment's renderer is wiki style renderer, If so try adding '\\' instead '\n', '\\' is used for line break in comments(when wiki style renderer is enabled).

Try this, may work but I dono, and I have not tried,

1) Try using <br> tags, or

2) Try encoding the new line char.

The above two suggestions may or may not work.

Hope this helps.

Both the suggestions doesn,t work for me, adding \\ too doesn't work for me.

PERL Code below worked

$update_comment =~ s/\n/\\n/g;

Just added one '\' in front of '\n' making it '\\n' worked.

not working with curl in bitbucket api for commit build status

@Muddassir Farooq Using `\\\\n` works with curl.

What worked for me is to replace the \r\n with \n.


issue.Description = description.Replace("\r\n""\n");
