(From emails with Kieth Chapman)
So I did some double checking, and I think I found the issue. The first email you sent has, sonar.resharper.report.path, singular. But the example online has, sonar.resharper.reports.path, plural. Didnâ€™t really occur to me at time, and since across Sonar the plugins use the plural typing (fxcop, gendarme, stylecop, gallio), I assumed it would be the same.
Modify plugin to support same property pattern (plural report name) as the other .NET plugins, since the target audience is the same and this will likely be a common point of confusion/misconfiguration
