Adding built in support for this was mentioned in Send status updates to hosted GitLab instances
@MartinStraub when we get to work on the built in support (meaning to do it without any Build Step) we’ll definitely support the self-hosted versions of the “big three” (GitHub, Bitbucket, GitLab).
Might take a bit more time for Bitbucket as the self hosted version of Bitbucket (Bitbucket Server) is quite a bit different compared to bitbucket.org, in fact it wasn’t even called Bitbucket initially, it was Atlassian Stash (https://www.atlassian.com/blog/archives/atlassian-stash-enterprise-git-repository-management), and even to this day these have separate API, webhook etc. formats, while GitHub and GitLab self-hosted have the same API & other formats as the .com hosted versions. In any case, a step for Bitbucket Server is definitely possible, similar to the existing GitHub Status (https://github.com/bitrise-steplib/steps-github-status) and GitLab Status (https://github.com/bitrise-steplib/steps-gitlab-status) steps. You can create a step if you have some time, it’s quite simple - a related recent blog post: https://blog.bitrise.io/how-to-create-and-share-your-own-bitrise-step
I just wanted to create a new feature request for this so it’s tracked. Are there any updates on this?
