Common Mistakes

Using PipelineJob instead of MultiBranchPipelineJob

Using FreestyleProject which does not support multi-branch pipelines

The MultiBranchPipelineJob is the correct job type to create a multi-branch pipeline in Jenkins.

💡 Hint

Common Mistakes

Using FTP URL which is not supported for Git SCM

Using SSH URL without proper credentials setup

The HTTPS URL https://github.com/example/repo.git is the correct format for the Git repository URL in Jenkins multi-branch pipeline.

💡 Hint

Common Mistakes

Using GitBranchSource which does not exist

Using SCMSource which is abstract and cannot be added directly

The BranchSource class is used to add a branch source to a multi-branch pipeline job in Jenkins.

4fill in blank

hard

Fill both blanks to configure the multi-branch pipeline job to scan branches every 1 day and set the script path.

Jenkins

job.setTriggers([new [1](1)])
job.setScriptPath('[2]')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using SCMTrigger which triggers on SCM changes, not periodic scans

Setting script path to pipeline.groovy which is not the default

PeriodicFolderTrigger schedules branch scanning every day, and Jenkinsfile is the default script path for pipeline jobs.

5fill in blank

hard

Fill all three blanks to complete the multi-branch pipeline job creation with credentials and orphaned item strategy.

Jenkins

job.setSources([new BranchSource(new GitSCMSource('[1]').withCredentials('[2]'))])
job.setOrphanedItemStrategy(new [3](7))

Drag options to blanks, or click blank then click option'

CDiscardOldItemsStrategy

DKeepAllItemsStrategy

Attempts:

💡 Hint

Common Mistakes

Using KeepAllItemsStrategy which never deletes old branches

Forgetting to set credentials causing SCM access errors

The Git repository URL is set to https://github.com/example/repo.git, credentials ID is github-credentials-id, and DiscardOldItemsStrategy removes old branches after 7 days.
