Resolution: Not A Defect
Centos 7 on local jenkins, Centos 6 on remote
Java 1.8 (open jdk)
When i try to import jenkins job from one instance (centos6.6) to another (centos7) (using plugin) i get error:
However, i thought the reason was on the remote jenkins instance, so i tried to import job on 3rd instance (centos6.6 too) and it succeeded.
I think the reason is in OS version difference.
Also i tried to copy job folders manually, then reload config, but still no succeeded, jobs are unseen.
