Support for unstable is in my opinion really important. In our situation a build job should be indicated unstable when any warnings, e.g. inspect warnings from resharper, are introduced. As a developer I would like to be notified with a yellow unstable marker if I introduced any into the system.

When checking the console log I see the following information:

// code placeholder
[Pipeline] stage
[Pipeline]{ (Declarative: Post Actions)
[Pipeline] echo
UNSTABLE
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // withEnv
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Posting build status of SUCCESSFUL to Jenkins2 InstanceFinished: UNSTABLE

 However in Bitbucket Server I see a green successful indicating the build is OK.

Environment:

• Atlassian Bitbucket v6.10.2
• [Jenkins 2.236
  Multibranch Pipeline|http://eyeonair.nl/]
• Bitbucket Server Integration 1.1.0
