We are not able to get the rpm info from the remote repository and not handling it properly
This is the error on the log

This is because there is no metadata on rpm packages from remote repo (even in the cache)
So rpm info cannot be retrieved.
The bug is on the null pointer exception.

To get rpm info on the rpm packages, user can move the content of the remote repo cache to a configured local yum repository and to calculate the metadata for it.

Comment by Leigh Jenkin [ 27/Jan/16 ]

This metadata needs to be calculated even for remote repos. Its the rpms that contain the relevant metadata and needs to be extracted on adding to the cache.

Right now there is no functional difference between a remote yum repo and a remote generic repo.

[root@ip-10-0-20-22 ~]# rpm -qpRl http://my-instance/artifactory/jenkins-yum-cache/jenkins-1.642-1.1.noarch.rpm
config(jenkins) = 1.642-1.1
rpmlib(CompressedFileNames) <= 3.0.4-1
rpmlib(PayloadFilesHavePrefix) <= 4.0-1

Now it works for both local and cache artifacts:
