Since our SCM projects are usually quite large, I'd like to only "clone" what's necessary to perform an automated build of a project from within Jenkins. The commandline interface to PlasticSCM, allows the creation of partial workspaces with cm partial. Is this also possible using the Jenkins plugin? Thank you!
I'm afraid the Jenkins plugin doesn't use partial workspaces but regular ones.
If you enable the "Use update" setting, Jenkins will not delete the workspace at the end of each build and the full update will only be performed the first time.
Also, you could create your own "cloaked.conf" entering custom rules to avoid downloading the full branch content. This way, you can also select the files to download in a regular workspace. But this is not directly handled by the Jenkins plugin. https://www.plasticscm.com/documentation/gui/plastic-scm-version-control-gui-guide.shtml#ColumnsintheWorkspaceExplorer
