Re: [Artifactory-users] Problem with empty folders in remote repository caches

[Noam Y. T. <no...@jf...>]

Hi Ken,

First off, I'd recommend that you perform an upgrade of your Artifactory
instance as many improvements were introduced to recent versions.
In regard to the error you're facing, in what types of repositories do you
see this happening? Only in remote repository caches or also in ordinary
local repositories?
The error you see is printed when an XML artifact cannot be parsed and
resolved; this is most likely caused by corrupt POM files; have you made
sure that POM validation is performed (see that the "Suppress POM
Consistency Checks" checkbox is unchecked in the configurations of the
affected repositories)?

HTH,
Noam
