From the stack trace (https://github.com/scoverage/scalac-scoverage-plugin/blob/1.1.0/scalac-scoverage-plugin/src/main/scala/scoverage/report/ScoverageXmlReader.scala#L57), this issue is related/caused by scoverage/scalac-scoverage-plugin#117.

Did you cleaned your project before first run with 1.1.0?

Thanks, @gslowikowski. git clean -xdf did the job.
