Java play 2.2.X application with findbugs4sbt does not generate Html report

[carestra]

Adding findbugs4sbt and configured with ReportType.Html
does not generate a Html report.
The play-consoles displays:
[play-findbugs4sbt] $ findbugs:findbugsReportType
[info] Some(-html)

The output directory (target/scala-2.10/findbugs/) has only the file "findbugs.xml"
For configuration see https://github.com/carestra/play-findbugs4sbt

The output file by default is "findbugs.xml," even if the output file type is HTML. This can be changed by modifying the findbugsReportPath key.
