Given that

• the base name of a Multibranch Pipeline project is the name given by the user
• the branch name of a Multibranch Pipeline project is the complete name of the branch for which the run has been triggered,

e.g.:

• base name = mylibrary
• branch name = newexcitingstuff,

 

we have a variable for "mylibrary/newexcitingstuff" (JOB_NAME), a variable for "newexcitingstuff" (BRANCH_NAME), another variable for "mylibrary/newexcitingstuff" (JOB_BASE_NAME), but no variable for "mylibrary". I know that I can parse that from JOB_NAME, but I believe the variable should be introduced.
