I wanted to use my JobDSL in Jenkins 2.426.3 with Job DSL 1.87, but it failed because it could not find the packages.
This worked with Jenkins 2.375.3 and Job DSL 1.82.
I checked the job settings in the Jenkins UI and saw a parameter named 'Additional classpath' for the older version. This is missing from the newer version.

You can see them in the attached files.

Please fix this problem or provide me with a way forward.
