Get information about other branches from within a Jenkinsfile

问题

Jenkins Blue Ocean is running on the same local network as a linked Bitbucket Server instance. A multibranch project in Jenkins is able to create a branch for each branch of a linked Bitbucket repository on the local Bitbucket Server. But within the Jenkinsfile, I am not able to get information about the other branches.

What specific syntax needs to be added to the simplified Jenkinsfile below in order for the resulting console log to:
1. Print a complete list of all the branches in the remote repository, and
2. Filter the list to include only those branches whose titles contain a specific substring xyx?

This question asks about Bitbucket repository branch information within the Bitbucket object model, which should be accessible via the Bitbucket API or CLI.

Jenkinsfile

The simplified code fo the Jenkinsfile is as follows. Note that I have already tried a few approaches:

node {
    // Clean workspace before doing anything
    deleteDir()

    try {
        stage ('Clone') {
            def repoUrl = checkout(scm).GIT_URL
            sh "echo 'The repo URL is: ${repoUrl}'"
            def branch = checkout(scm).GIT_BRANCH
            sh "echo 'The name of the branch containing the commit for this build is: ${branch}'"
            sh "git remote show"
            sh "git remote show origin"
        }
    } catch (err) {
        currentBuild.result = 'FAILED'
        throw err
    }
}

The preceding Jenkinsfile is not isolating the intended information.

The Logs

The complete logs that result from running the preceding Jenkinsfile are as follows:
