Jenkins artifacts are not deleted from s3 bucket when a pipeline job get deleted or a branch get deleted in a multi branch pipeline.

How to reproduce

• Use any git repo to create a jenkins multi branch pipeline named produce_bug using the Jenkinsfile below.
• Create a branch named testing
• Build the branch testing twice
• Assuming the build numbers are #1 and #2, artifacts will be uploaded to s3 to produce_bug/testing/1/ and produce_bug/testing/2/ folders

First test case: 

• delete build #1 using the jenkins button Delete build #1 
  • Directory produce_bug/testing/1/ is being deleted from s3
  • Works as expected 

Second test case: 

• Delete the branch testing

• • The job for the branch testing is being deleted from s3
  • The directory produce_bug/testing/ is not being deleted from s3
  • Does not work as expected! produce_bug/testing/ should be deleted from s3

Third test case: 

• Delete the multi branch pipeline produce_bug

• • The directory produce_bug ** is not being deleted from s3
  • Does not work as expected! produce_bug/ should be deleted

// Jenkinsfile
pipeline {
    agent any
    stages {
        stage("demo") {
            steps {
                writeFile file: 'f', text: 'some content here'
                archiveArtifacts 'f'
            }
        }
    }
