I have 2 jobs. One is a regular freestyle job on Jenkins that is supposed to trigger another job which is a Multibranch pipeline job.
The issue is whenever I enter the name of the Multibranch job in the "Projects to Build column", I get an error - "x is not buildable". But the Multibranch job works perfectly well on its own and there are no problems with it.
Is "Build other projects" post build action (downstream project) not compatible with Jenkins pipelines? What am I missing here?
