@Mark thank you for the reply but i beg to differ.
Please understand that the issue is not what about a plugin reference in
the old versus in the newer version (whether you go for long term release
or weekly release)
My Jenkins job has a single "execute shell" that prints "Hi" message. so
plugin dependency is not the reason for the error.
You can replicate the issue on the said versions of Jenkins. Create a very
basic Jenkins DSL job in older version with no plugin dependencies. Then
copy the job to the newer stable Jenkins release. You will still see the
error I'm reporting.
