Notification Policy + Webhook (recommended workaround)
You can use a Spacelift notification policy with a webhook to override the commit status when a run is discarded. The approach:
Create a named webhook endpoint in Spacelift that points to your Bitbucket Server's build status API
Write a notification policy that fires when run.state == "DISCARDED" and POSTs a corrected status (CANCELLED) to Bitbucket, overwriting the FAILED status Spacelift already sent
Example policy (Rego v1):
rego
package spacelift
webhook contains wbdata if {
some endpoint in input.webhook_endpoints
endpoint.id == "bitbucket-build-status"
run := input.run_updated.run
run.state == "DISCARDED"
stack := input.run_updated.stack
wbdata := {
"endpoint_id": endpoint.id,
"payload": {
"key": sprintf("spacelift/%s/%s", [stack.id, run.type]),
"state": "CANCELLED",
"url": sprintf("https://your-spacelift-account.app.spacelift.io/stack/%s/run/%s", [stack.id, run.id]),
"name": sprintf("Spacelift - %s (discarded)", [stack.name]),
"description": "Run was discarded by user",
},
"method": "POST",
}
}
The webhook endpoint URL in Spacelift would be:
https://your-stash-instance/rest/api/latest/projects/{projectKey}/repos/{repoSlug}/commits/{commitHash}/builds
The tricky part here is that the commit hash is available in the policy input (input.run_updated.run.commit.hash) but you can't dynamically construct the webhook endpoint URL per-request — the endpoint is static. To work around this, you'd need a lightweight intermediary (a Lambda, a simple proxy, or a Bitbucket plugin) that receives the webhook from Spacelift, extracts the commit hash from the payload, and forwards the build status to the correct Bitbucket API path.
Problem
The status of discarded stack runs show as failed in VCS.
