Possible NPE when DataBound Object attribute is not Describable

See original GitHub issue

Your checklist for this issue

🚨 Please review the guidelines for contributing to this repository.

  • Jenkins version 2.200
  • Plugin version 1.32
  • OS Linux

Description

The DataBoundConfigurator#describe method can throw a NPE when the instance contain an attribute that is abstract and not of Describable class when BaseConfigurator#createAttribute is called.

This actually happens with FileCredentialsImpl#file. Which leads to export error:

credentials:
  system:
    domainCredentials:
    - credentials: |-
        FAILED TO EXPORT

Hmm best effort may be to log that the field is not exportable and should be reported to given plugin.

We should be able to log to administrator monitor for more visibility too? Then still export other fields? Although admittedly for FileCredential that would not work.

I believe FileCredential needs a fix.
