The build flow job type does not initialize the project's workspace. However, this project supports options, like SCM, that require a workspace to be initialized. This means:

1. build-flow projects cannot use SCM
   • build-flow projects cannot be triggered by SCM changes if that trigger requires a workspace. Due to JENKINS-20767 all Git triggered projects currently require a workspace.
2. build-flow projects cannot use any post-build action that assumes a workspace. EG: archive artifacts
