Resharper CLT - inspectcode on .net core project

I've setup an TFS 2018 with the resharper plugin and downloaded the latest resharper clt. I've setup the code inspection in my build process and i got the following results when building my app:

inspectcode will be issued with this command: 

System.Management.Automation.ItemNotFoundException: Cannot find path 'C:\Data\Resharper\Reports\CodeInspection_92.xml' because it does not exist.

System.Management.Automation.ParameterBindingValidationException: Cannot validate argument on parameter 'Xml'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again. ---> System.Management.Automation.ValidationMetadataException: The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.

When trying to run the same from the command line I got the following results:

C:\Data\Resharper>inspectcode.exe "C:\agent\_work\9\s\myproject\myproject.csproj" /o:"C:\Data\Resharper\Reports\CodeInspection_92.xml"
JetBrains Inspect Code 2018.1.4

No files to inspect were found.

It seems like that when running in the build process the xml file can not be written (rechecked ntfs access rights) anyhow I got a completly different errormessage when running from cmd. Please help! Br, Mario
