Running Resharper Code Inspections with a Resharper Plugin (Download option)

I'm currently trying to run Resharper Code Inspection (Resharper CLT 2019.1.1) together with the XmlDocInspections plugin.

I am able to run the inspections with the plugin only if I copy the plugin nuget package into the folder where the Resharper CLT executable resides.

What I would like to achive is the usage of the "R# CLT Plugins" build step by using the "Download" option. What I did so far is:

1. Specify the plugin: Download ReSharper.XmlDocInspections/2.7.0.6690191

2. Add the nuget source

As my teamcity agent runs as system user its appdata environments points to C:\Windows\system32\config\systemprofile\AppData\Roaming, I added the package source to the NuGet.config under C:\Windows\System32\config\systemprofile\AppData\Roaming\NuGet:

<add key="jetbrains.com" value="https://resharper-plugins.jetbrains.com/api/v2/" />

That did not cause the plugin to be used. Did I miss any step? I also tried to use the "-x=ReSharper.XmlDocInspections" R# CLT parameter, but that did nothing either. Any ideas?

Thanks and regards
