after upgrading from Jenkins 2.99 to 2.104 and Updating all of the Plugins including Multibranch Pipeline i noticed that "trunk" in all Multibranch Projects was missing.
Only branches and deleted branched existed.
We are still using Subversion as SCM and nothing changed here.
Include branches: "trunk,branches/,tags/"
I tried a few other selctors here without any success.
Multibranch log even stated trunk is there
"Will not remove trunk because it is new"
Any suggestions whats wrong here?
