I'm building a .NET script in which I have a post build step executing a windows batch command:

fxcopcmd /file:HelloWorld\bin\HelloWorld.dll /out:fxcop-report.xml /s
exit 0

I have check the 'Violations' option and next to the fxcop XML filename pattern, I have placed 'fxcop-report.xml'

After the build I know there were 14 violations placed in the xml file, but I'm not seeing any results in the graph view of the violations, and when I click on the graph it doesn't even specify out that fxcop was picked up (see screenshot).

UPDATE: This only affects a maven 2/3 project. If I build a free-style project, I get the violations to show up.
