Can Bitbucket Server limit the size of message content in Slack plugins?


My customer is using the Slack plugin installed on their Bitbucket Server.

My client wants to limit the sending of too much content when an event occurs on Bitbucket.

So I found the "slack.addon.unfurl.file.max.lines" option in the path below, and entered slack.addon.unfurl.file.max.lines=3 in, but it does not apply.

Is the correct setting place or is the setting correct? Or I'm wondering if I need to set it up somewhere else.


Thank you.

Hey @Sung Hyun Ryu,


slack.addon.unfurl.file.max.lines should be set as an environment variable passed to the Bitbucket Server process. It should limit the size of repository file previews, when someone pastes a link to a source code in slack.

If that's not what you are looking for, there's also an option when configuring channel notifications for repositories. While creating or editing a connection between a channel and a repository, you can chose between Basic and Extended verbosity. Switching to Basic should reduce the amount of space notifications take in Slack.


Hope that helps. Cheers!
