"java.lang.Exception: None or multiple repos" with BitBucket Notifier in Jenkins multi-branch pipeline

Question

I have a multi-branch declarative pipeline on Jenkins, which gets triggered by repo events from my Bitbucket cloud account and I'd like it to report the result back to Bitbucket.

My Jenkinsfile looks as follows:

pipeline {
    agent any
    stages {
        stage('Prepare Env') {
            steps {
                bitbucketStatusNotify(buildState: 'INPROGRESS')
                sh "npm i"
            }
            post {
                success {
                    bitbucketStatusNotify(buildState: 'SUCCESSFUL')
                }
                failure {
                    bitbucketStatusNotify(buildState: 'FAILED')
                }
            }
        }
    }
}

I discovered that the second and all consecutive commits to a pull request cause a condition when Jenkins build fails when notifying Bitbucket of the build result with a message: java.lang.Exception: None or multiple repos.

This is somehow coherent with one of the first lines in the log saying: Fetching changes from 2 remote Git repositories.

However, I actually only have one repository and no idea why Jenkins recognises it as multiple.

How I can make my build stop seeing multiple repos and succeed?

Short answer: Remove all the bitbucketStatusNotify calls. Notifications are implicit as it's a bitbucket job.

Long answer: After having spent 3 hours with the same error, we saw the problem is related to the "bitbucketStatusNotify" plugin.

The error you pointed "Fetching changes from 2 remote Git repositories" seems to be related to how jenkins manage the PR jobs, and it makes the bitbucketStatusNotify plugin fail.

As it's a bitbucket plugin job, the notifications to bitbucket are done automatically, so if you remove the bitbucketStatusNotify calls, it should work as expected
